Abstract: Abstract When amperometric biosensors drift, their sensitivity drops with time: the same difference in detected concentration value Δ C results in lower sensor output current Δ I as the measurement/monitoring time progresses. This limitation affects… read more here.

Abstract: There are limited data on amperometric biosensors (ABSs) for L-arginine (Arg) determination based on oxidases that produce hydrogen peroxide (H2O2) as a byproduct of enzymatic reaction, and artificial peroxidases (POs) for decomposition of H2O2. The… read more here.
