what is the formula of Rf?
Rf = distance moved by spot / distance moved by solvent
what is a biosensor?
a device which responds to the presence of a specific analyte by producing an electrical signal proportional to the concentration of the analyte
what are the 3 components of a biosensor?
receptor
transducer
electronics
what is the receptor part of the biosensor?
composed of immobilised, biologically sensitive material (biocatalyst)
what is the most important role of the biocatalyst?
its role in the transmittance of an energy impulse proportional to the reaction of the biocatalyst with the measure analyte
what does the receptor require?
intimate contact with a suitable transducing system
what is a transducer?
an electrical device which converts the effects of the biocatalystical reaction into forms which can be electronically amplified, store and displayed
what are some examples of things which can be transduced by a transducer into electronic output signals?
changes in pH
ionic concentration
light emission
