Nanomonitors: Electrical Immunoassays for Protein Biomarker Profiling

Bothara M.G., Reddy R.K., Barrett T., Carruthers J., Prasad S., Portland State University, US

Robust diagnosis of a disease can be accomplished by reliable detection of multiple protein biomarkers. Traditional assay methods for protein detection such as enzyme-linked immunosorbent assay (ELISA) have several limitations – need for use of [...]

Nanomonitors: Electrical Immunoassays towards Clinical Diagnostics

Bothara M., Prasad S., Barrett T., Carruthers J., Portland State University, US

We present here the development and tetsing of a protein biosensor operating on electrical capacitance changes as a measure for idnetifying protein biomarkers that are indicators of vulnerale coronary vascular plaque. The prototype of the [...]

Nanoporous Alumina Membranes Based Microdevices for Ultrasensitive Protein Detection

Bothara M.G., Reddy R.K., Barrett T., Carruthers J., Prasad S., Portland State University, US

This research focuses on using the electrical and chemical properties of nanoporous alumina membranes to improve the sensitivity and performance of Si-based microdevices for protein sensing. The integration of nanoporous membranes with the microdevice results [...]
