Development of next-generation microfluidic systems for enhanced, faster, and cost-effective immunoassays for tissue diagnostics - Ac electrothermal flow & Acoustofluidics

The application of microfluidics in the field of surface-based assays and more specifically, the spatial molecular profiling of tumor tissues has gained a lot of interest, especially with the increased interest in personalized medicine and targeted therapy ...

Efficient AC electrothermal flow (ACET) on-chip for enhanced immunoassays

Martinus Gijs, Diego Gabriel Dupouy, Muaz Salama Abdelmonem Draz

Biochemical reaction rates in microfluidic systems are known to be limited by the diffusional transport of reagents, leading often to lowered sensitivity and/or longer detection times in immunoassays. Several methods, including electrically powering electr ...

How specific are the conformation-specific α-synuclein antibodies? Characterization and validation of 16 α-synuclein conformation-specific antibodies using well-characterized preparations of α-synuclein monomers, fibrils and oligomers with distinct structures and morphology

Hilal Lashuel, Somanath Jagannath

Increasing evidence suggests that alpha-synuclein (α-syn) oligomers are obligate intermediates in the pathway involved in α-syn fibrillization and Lewy body (LB) formation, and may also accumulate within LBs in Parkinson's disease (PD) and other synucleino ...

Memristive Biosensors based on Full-size Antibodies and Antibody Fragments

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki, Sébastien Naus

For the first time memristive biosensors developed by the incorporation of scAbs (single-chain antibody fragments) enabling label-free detection of free Prostate Specific Antigen (fPSA) for early-stage detection of prostate cancer (PC) are reported. In add ...

Bioluminescent Antibodies for Point-of-Care Diagnostics

Kai Johnsson, Rudolf Griss, Alberto Schena, Qiuliyang Yu, Lin Xue

We introduce a general method to transform antibodies into ratiometric, bioluminescent sensor proteins for the no-wash quantification of analytes. Our approach is based on the genetic fusion of antibody fragments to NanoLuc luciferase and SNAP-tag, the lat ...

Image processing on reconfigurable hardware for continuous monitoring of fluorescent biomarkers in cell cultures

Julien Michel Ghaye

Fluorescence microscopy is a widespread tool in biological research. It is the primary modality for bioimaging and empowers the study and analysis of multitudes of biological processes. It can be applied to fixed biosamples, that is samples with frozen bio ...

Diagnostic microchip to assay 3D colony-growth potential of captured circulating tumor cells

Matthias Lütolf, Stefan Kobel, Samy Gobaa

Microfluidic technology has been successfully applied to isolate very rare tumor-derived epithelial cells (circulating tumor cells, CTCs) from blood with relatively high yield and purity, opening up exciting prospects for early detection of cancer. However ...

Controlled synthesis of fluorescent silica nanoparticles inside microfluidic droplets

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker, Ioannis Lignos

We study the droplet-based synthesis of fluorescent silica nanoparticles (50–350 nm size) in a microfluidic chip. Fluorescein-isothiocyanate (FITC) dye is first chemically linked to aminopropyl triethoxysilane (APTES) in ethanol and this reaction product i ...

Labelling cell structures and tracking cell lineage in zebrafish using SNAP-tag

Kai Johnsson, Sambashiva Banala, Mako Kamiya

We present a method for the specific labelling of fusion proteins with synthetic fluorophores in Zebrafish. The method uses the SNAP-tag technology and O-6-benzylguanine derivatives of various synthetic fluorophores. We demonstrate how the method can be us ...

Chronic delivery of antibody fragments using immunoisolated cell implants as a passive vaccination tool

Rolf Gruetter, Maria del Carmen Sandi Perez, Patrick Aebischer, Maurizio Molinari, Maria Isabel Cordero Campana, Jean-Charles Bensadoun, Nicolas Bouche, Veronica Setola, Osiris Marroquin Belaunzaran

BACKGROUND: Monoclonal antibodies and antibody fragments are powerful biotherapeutics for various debilitating diseases. However, high production costs, functional limitations such as inadequate pharmacokinetics and tissue accessibility are the current pri ...
