Abstract

The Computer Screen Photo-assisted Technique (CSPT) utilizes a computer screen as a light source and a web camera as a detector for optical measurements. This provides a ubiquitous instrumentation for several bioanalytical situations. In the present contribution we first describe CSPT briefly, demonstrate the possibility to make optical fingerprinting of fluorescent color indicators and give a mini-review of our recent demonstration of CSPT based surface plasmon detection. Although we have no results yet specifically aimed at real biosensing, we point out the possibilities to make affinity based biosensing with CSPT.
