Autoantibodies associated with risk of subclinical autoimmunity and immune-related adverse events from checkpoint immunotherapy
UNIVERSITY OF TEXAS SOUTHWESTERN MEDICAL CENTER
Immune checkpoint inhibitors have emerged as highly promising treatment for lung cancer. However, some patients develop immune adverse events. We collected serum from 78 patients treated with immune checkpoint inhibitors and determined autoantibody profiles against 125 autoantigens. In general, the greatest increases in autoantibody levels were among individuals with the highest baseline autoantibody levels. Elevated baseline levels of autoantibodies were associated with the development of immune-related adverse events, with 4 autoantibodies having significantly higher levels in the toxicity group (P<0.05). Immune-related adverse events were also more common among cases with greater post-treatment increase in antibody levels, with 10 antibodies significantly increased in toxicity group (P<0.05). These autoantibodies may potential markers for prediction of immune-related adverse events from immune checkpoint therapy.
Impedance spectroscopy with fish cell lines to create a biosensor on a chip for chemical impact monitoring
SWISS FEDERAL INSTITUTE OF AQUATIC SCIENCE AND TECHNOLOGY (EAWAG)
Fish are important indicator species for the aquatic environment, and millions of fish are sacrificed annually in toxicity experiments. One alternative is the use of fish cells; cell lines of different species and organs exist, can be cultured in the lab indefinitely, and employed in a variety of in vitro assays. One such assay is impedance sensing: cells are seeded on an electrode chip and resistance is measured in real-time, reflecting the health status of the cells. A decrease in resistance is an indicator for loss of cell viability as can be elicited, for example, by exposure to chemicals. We develop such setups for flow-through exposures and water quality monitoring.
Gate-coupling and Single-trap Effects for Sensitivity Enhancement in Nanowire Field-effect Transistor Biosensors
FORSCHUNGSZENTRUM JÜLICH, BIOELECTRONICS (ICS-8)
Nanowires are unique nanomaterial promising for many fundamental studies as well as for nano - and bioelectronics applications. We develop biosensors based on nanowires for the early detection of cardiovascular and Alzheimer’s diseases. Based on our comprehensive studies on transport and noise phenomena in the fabricated devices, we propose novel approaches on the basis of gate-couling and single-trap effectrs for the detection of the target biomarkers with enhanced sensitivity for advanced biosensing. The developed approach opens prospects for diagnosis of the diseases in real-time at the early stages when therapy can be effectively applied to restore the healthy state of the patient.
Bringing biological content into Biochip and Biosensor systems: Scaling of multiplexed diagnostic test production on Biochips and Biosensors using ultra-low liquid volume dispensing
Most rapid diagnostic tests work by capturing molecules on a solid surface. Surfaces can contain discrete binding sites for analytes carrying a specific capture molecule. The trend in the miniaturization of diagnostic test systems with the intention to increase throughput and decrease cost, requires precise handling of picoliter to nanoliter liquid volumes. Due to the possibility to use only picoliter amounts of reagents, test production costs can be significantly decreased. In addition, due to the smaller feature size of the analytes, introducing multiple other analytes onto the same test area can be easily achieved. A technology platform for seamless use from R&D to production, which delivers ultra-low volumes very accurately onto any surface, enables short development times. Sophisticated optical systems for online alignment, calibration and quality control of goods produced are important from the first development steps. www.scienion.com
An apparatus for instant DNA-identification using antenna-enhanced fluorescence
FRAUNHOFER INSTITUTE FOR PHYSICAL MEASUREMENT TECHNIQUES IPM
Single molecule detection via plasmonic amplification of fluorescence may become an alternative to PCR. We present a novel apparatus designed for the point-of-care, which can prepare, conduct and analyze plasmonic assays on a chip. In comparison to conventional PCR methods, the device benefits from a reduced technical complexity. This is reflected in the small sized low cost device, and a fast analysis. Additionally, the method can – in principle – also be applied to different targets like antibodies/antigens. A disposable cartridge is used to process the chemical reactions. Fluorescence signals from a microarray are detected in a miniaturized microscope with < 2 µm resolution. The technical realization and first results for amplified DNA-detection are subject to this presentation. Funded by BMBF, 03VP03892.
A universal platform for nucleic acid based point-of-care diagnostics
FRAUNHOFER INSTITUTE FOR PHYSICAL MEASUREMENT TECHNIQUES IPM
We developed a novel platform based on polymerase chain reaction (PCR). By combining microfluidic integration and a fully automated processing unit, we achieve an overall processing of about 45 minutes. The microfluidic elements are combined into a disposable disk with no active elements which has all reagents prestored. All active components, particularly the rotation unit, the heating unit, and the fluorescence readout module are integrated into a fully automated device designed for the point-of-care. The functional units of the platform will be presented. Special emphasis is given on the fast thermocycling based on a non-equilibrium approach with direct infrared liquid heating. The platform has been tested with assays for resistant pathogens. Funded by BMBF, 031A586C.

The mycotoxin detection by graphene-based aptasensor
We report an on-chip aptasensor for ochratoxin A (OTA) toxin detection that is based on a graphene field-effect transistor (GFET). Graphene-based devices are fabricated via large-scale technology, allowing for upscaling the sensor fabrication and lowering the device cost. The sensor assembly was performed through covalent bonding of graphene’s surface with an specific to OTA aptamer. Fast (within 5 min) response to OTA was demonstrated with a detection limit of 4 pg/mL. We demonstrated the regeneration of sensor with time constant of the sensor only 5.6 s, meaning fast sensor regeneration for multiple usages. The high reproducibility of the sensing response was demonstrated via using several recycling procedures as well as various GFETs. The developed platform opens the way for multiplex sensing of different toxins using an on-chip array of graphene sensors.
The Power of a Micropump
INSTITUT JEAN LAMOUR/UNIVERSITÉ DE LORRAINE
Knowledge of the electromagnetic properties of cells can provide early signals of disease or abnormal conditions in the human body for medical applications. In combination with microfluidic devices, impedance spectroscopy can be a powerful tool for sorting, analyzing, counting and discriminating cells. Thus we propose a microfluidic biosensor combined to a matrix-shaped structure of electrodes. It allows different configurations of measurement such as single cell, agregat of cells or tomography. From the results already obtained, we show a good sensibility to detect a single sample of 10 µm and a backer yeast culture difference.
Online Monitoring of The Power of a Micropump
In this talk, a bulk Si-based micropump based on an electrostatic driving principle called nanoscopic electrotstatic drive (nano E-drive or just NED) will be presented. A comparison to commercially available micropumps will be given as well as first characterization results. Furthermore, the same actuation principle can be used to create valve components which can be merged with the micropumps. An outline includes possible fields of application.
Mechanical Contribution of stromal cells to the formation of human vasculature
UNIVERSITY COLLEGE LONDON
This is a project which is on the role of stromal cells in the formation and stabilization of human blood vessels. To address that we employed a microfluidic platform consisted of 3 channels. Also we recruited GFP-endothelial cells and normal human lung fibroblasts. By mono-culturing and co-culturing ECs, also applying chemical inhibitors and si-RNA approach to perturb some genes belonging to mechanotransduction pathways, we could show that fibroblasts contribute mechanically to the human vessel formation.
Microfluidic drop reactors for fabrication in drug delivery
UNIVERSITY OF BIRMINGHAM
Microfluidics provide the opportunity of formation and manipulation of monodisperse drops of submillimetre size with possibilities for drug encapsulation. Drops can be further solidified in tailored way to guarantee the prescribed drug release profile. The main problem in microfluidic production of solid particles is channel clogging. Here we suggest a combination of flow microfluidics with drop microreactors which enables avoidance of this problem. As an example we use the synthesis of alginate gel particles by drop coalescence allowing isolation of a gelated alginate particle inside the drop of calcium chloride moving inside the continuous oil phase. The properties of alginate particles can be controlled by mass transfer inside the combined drop, being a function of process parameters.
Amino acids and their derivatives as platforms for photonic integrated circuits
HOLON INSTITUTE OF TECHNOLOGY
Bioinspired peptide nanostructures have gained much attention in recent years in the field of nanotechnology and are considered as a new frontier in materials science. These bioorganic materials are self-assembled into nanoarchitectures of different morphology and size, and have crystalline structure. Optical waveguiding phenomena in bioinspired nanostructures can be used to revolutionize emerging fields of precision medical trials and health monitoring In this talk, I will present various types of bioinspired materials and show how these materials can be used as raw materials for photonic integrated devices. I will focus on optical waveguiding property in Histidine-based back-to-back trapezoid microstructure, and show top-down approach to construct various types of optical devices based on derivatives of Phenylalanine amino acid.
Artificial leukemic bone marrow on a chip
KARLSRUHE INSTITUTE OF TECHNOLOGY
We have developed a model of a leukemic bone marrow for the in vitro evaluation of chimeric antigen receptor-T- cell (CAR) specificity and potency. The model is based on a polymer microcavity array that is arranged on a chip which is then inserted into a bioreactor housing. For the establishment of the model we used human mesenchymal stromal cells and the ALL line Nalm-6. After 24 h of co-culture we added 3rd generation chimeric antigen receptor (CAR)-T-cells (effector:target-ratio = 10:1) and cultivated the chip for 72 h. With this model we were able to show that CAR-T-cells attack leukemic cells in their niche and that after 72 h only 12% of the leukemic cells could be detected.
PAcrAm™-Biosense: a single-step biofunctionalization for highly sensitive diagnostics
Until today selective and targeted functionalization in biochips and IVD-devices remains challenging. Particularly the bio-functionaltion of sensing devices, specifically reactive to a target moiety, while preventing any non-specific interactions with the sensing interface. In this contribution we will present PAcrAm™-Biosens, a novel biosensing surface-functionalization routine that is able to improve selectivity, reduce non-specific binding and provide stable multimodal surface function for surface-bound in-vitro diagnostics. Combining non-fouling polymers with reaction-specific azides (N3), we demonstrate the excellent performance of the PAcrAm™-Biosense coating in targeted binding of functionalized biomolecules. Thereby, PAcrAm™-Biosens combines the unique features of providing both low non-specific binding and targeted specific binding in a single dip-and-rinse coating applied from aqueous solutions, compatible with state-of-the-art production processes. www.susos.com
Novel approaches for developing of self-assembled protein microarrays for non-contact printers robots
CANCER RESEARCH CENTER. UNIVERSITY OF SALAMANCA-CSIC
Understanding the dynamic of the proteome is a critical challenge because it requires high- sensitive methodologies in High-Throughput (HT) formats in order to decipher its modifications and complexity. HT experimental proteomics techniques are essential to provide valuable functional information of the proteins, peptides and the interconnections between them. Hence, Nucleic Acid Programmable Protein Arrays ( NAPPA), as a proteomics technology has been successfully employed in several research areas towards innovative diagnostic and therapeutic applications. Here, it is presented a novel approach to design and developed self-assembled protein arrays in a non-contact printer with outstanding advantages which have been successfully applied in study host-pathogen interactions and serum profiling for biomarker discovery in auto-immune and tumoral diseases.
Organ on a chip for modeling tumorigenesis and primary ovarian cancer metastasis
UNIVERSITY OF ILLINOIS AT CHICAGO
Ovarian cancer is the 5th leading cause of cancer related death in women. It is now recognized that a large percentage of high grade serous ovarian cancers arise in the fallopian tube and colonize the ovary as the primary metastatic step. Since one of the largest tumor masses tends to be found in the ovary after diagnosis, this raises the possibility that the ovary contributes to tumor spread and aggressiveness. One of the risk factors associated with ovarian cancer is the lifetime number of ovulations. Few models are currently available that allow the process of ovulation and the development of ovarian cancer to be studied. To address this gap, we propose to create in vitro models of the fallopian-ovarian interaction within a normal ovulation context to examine key aspects of the ovarian microenvironment during tumor initiation and progression.
Precise Contactless Spotting for Lab-on-Chip Applications
MICRODROP TECHNOLOGIES GMBH
Lab-on-chip devices as small microfluidic devices equipped with microchannels carry out diagnostic tests by enabling reactions between patient samples and reagents. The devices deliver test results with very small sample volumes in a short period of time. For production of lab-on-chip devices a precise, fast material deposition method is needed. Typically, the devices are produced at high numbers under high throughput conditions. The substrates may be made of different materials but all have a structured surface like channels. Deposition or Spotting of reagents onto the chip is a demanding task and requires filling of small cavities and microchannels with a high accuracy. This can be done with a microspotting platform based on in inkjet technology. The flexibility of this technology allows solutions adapted to the specific customer needs. It is demonstrated how high accurate the volume of spotted reagents and precise of placement is achieved under high throughput production conditions. www.microdrop.de
