Electrochemiluminescent sensor for clinical analysis based on Carbon Nanotube electrodes

Sanginario A., Demarchi D., Giorcelli M., Castellino M., Politecnico di Torino, IT

Presented application is based on the use of carbon nanotubes (CNTs) for biomolecular analysis using electrochemiluminescence (ECL) detection technique. For this purpose we have grown self standing cylinder-shaped blocks of Multi wall CNTs (MWCNTs) by [...]

Non-labeled DNA Biosensor Post-Processing Signals Analyses

Afuwape S.A., National University, US

The evolution of DNA biosensors should match commercial emergency of Nanotechnology in this genomic era. The ubiquitous oligonucleotide microarray ‘lab–on-chip’ is limited by high cost and man-power. However, emerging portable non-label DNA biosensors are yet [...]

Phosphate recognition using multilayer charged thin films containing zirconium (Zr) ions for biochip applications

Lee M., Kim J.H., Kim N., Kim S-H, Kim J.H., Kim N., Kim S-H, Shin C.-J., Koh K., Kim J.H., Kim N., Kim S-H, Ajou University, KR

The phosphate residue plays an important role as not only the structural component of DNA and lipid but also the activation signal of protein in the cellular signaling pathways. Therefore, the selective recognition for the [...]

Nanospring™ Enhanced Enzyme-linked Immunosorbent Assay for Increased Sensitivity and Early Detection

Beaux M.F., Cantrell T., Prakash T., Corti G., McIlroy D.N., Norton M.G., GoNano Technologies, Inc., US
