Notes:
Electroanalytical flow-through measurements with L-lactate- and β-D-glucose-biosensors using reference sera showed that only by an ion-impermeable but gas-permeable PTFE membrane separating enzyme membrane and electrochemical measuring cell, the high selectivity of oxidases can fully be utilized. For clinical-chemical serum analysis biosensors with O2-detectors are to be preferred which are at least equivalent to photometric comparing methods. Too high values found in measurements using H2O2-detectors are caused by undesired reactands being anodically converted. At O2-sensitive enzymatic L-lactate- and β-D-glucose-biosensors, inevitable biological fouling by O2-consuming microorganisms can be controlled by the use of glutardialdehyde.
