Experimental study of sensitivity enhancement in SPR biosensors by use of zinc oxide intermediary layers

Chiu N.-F., Dutt S., Evoy S., Lin C-W, Nelson-Fitzpatrick N., Singh A., National Taiwan Normal University, TW

We report a novel design for the intermediary layer of surface plasmon resonance (SPR) devices that use high refractive index and high-transmittance zinc oxide (ZnO) dielectric layers to enhance the signal quality and improve the [...]

Chromatographic Purification of Bacteriophages for Improved Surface Capture of Bacteria – Towards a General Approach

Arya S., Evoy S., Glass N., Naidoo R., Singh A., National Institute for Nanotechnology, University of Alberta, CA

We report in this study the largest surface capture density of E Coli using the wild-type T4 bacteriophage; whereby higher surface capture density can enable higher sensitivities for surface-based biosensors. This was possible due to [...]

SiCN nanomechanical resonators for array-based biosensor applications

Evoy S., Guthy C., Singh A., Tanha J., University of Alberta, CA

Rapid, sensitive and inexpensive analysis of biological molecules is of great importance to many biomedical applications, such as disease detection and monitoring, drug discovery, detection of pathogens, etc. Mechanical resonators have been demonstrated as highly [...]
