A two channel SPR for parallel or differential SPR measurements in liquids or in gases with wide angle range up to 17 degrees.

Rapid Screening - A Challenge

Surface Plasmon Resonance on thin metal layers is known for a long time and one of the most sensitive label-free methods for the measurement of the reaction dynamic of biological molecules on gold surfaces. A typical application of SPR is the field of biosensors, now employed in medicine, biotechnology and environmental monitoring.

As far as blood is concerned, it usually will take 12 hours of lab work to know whether a sample is safe.

This may be quite a long time for the case of blood donations, yet
it is far too long a time for organ transplantions.

However, until now there exists no fast AND sensitive method to know whether the donor is infected or not.
