The selectivity features of a biological functionalized carbon nanotubes complex towards blood

Cortes P., Fagan D., Olszewki A., Radetic M., Abdallah G., Youngstown State University, US

The present work has studied the selectivity process of a biological complex based on Carbon Nanotubes and a specific amino-acid sequence for interacting specifically with blood. In this work, Human Serum Albumin (HSA) has been [...]

Diamond-based Biosensors with an Impedimetric and Label-free Read-out

Vermeeren V., Bijnens N., Grieten L., Wenmackers S., Vanden Bon N., Haenen K., Wagner P., Michiels L., Hasselt University, BE

Healthcare and diagnostics are moving towards molecular medicine. Hence, a lot of research is being performed on biosensors. However, rarely one has reached the commercialization phase because of the expensive infrastructure required for signal read-out. [...]

Towards rational de novo design of peptides for inorganic interfaces

Biggs M.J., University of Edinburgh, UK

Proteins at inorganic interfaces occur across science, technology and nature – protein arrays, prostheses such as stents and artificial heart valves, biomimetic assembly of nanoparticles, and anti-freeze proteins are just a few examples from many. [...]

Parallel two channel near and far field fluorescence microscopy

Verdes D., Rabe M., Seeger S., University of Zurich, CH

We report a new two channel fluorescence microscopy technique for surface-generated fluorescence. The realized fluorescence microscope allows high resolution imaging of aqueous samples. The core element of the instrument is a parabolic mirror objective that [...]

Specific and Non-specific adsorption of Proteins on Solid Interfaces

Rabe M., Zimmermann J., Verdes D., Seeger S., University of Zurich, CH

We present a comprehensive mechanistic study of the non-specific adsorption of β-Lactoglobulin on a solid interface by comparing the adsorption kinetics of this protein to theoretical predictions of reported models. Important experimental observations were increasing [...]

Multi-plex biomolecular detection using Bio-nanotransduction

Branen J.R., University of Idaho, US

Bio-nanotransduction is a biological detection scheme that is based on biological recognition (Bio) and the production of biological nano-signals which allows the change of recognition event into universal signal molecules (nanotransduction). A single sample can [...]
