The method solves the reversion of polarity by negation as well as the determination of polarity intensity. Last two problems require a word combination processing. The word combination processing needs a dynamic coefficient setting...
We present a new optical biosensor concept based on hydrogel waveguides with integrated fluorescent proteins developed as a platform for implantable sensors. In this prototype the sensor detects the presence or absence of calcium through changes in fluorescence resonance energy transfer (FRET) induced by conformational changes of a FRET protein. The protein is immobilized in a synthetic hydrogel matrix...
