An amperometric biosensor based on laccase, from Trametes versicolor (LTV), was developed and optimized for monitoring the phenolic compounds content in tea infusions. The fungal enzyme was immobilized by entrapment within polyvinyl alcohol photopolymer PVA-AWP (azide-unit pendant water-soluble photopolymer) onto disposable graphite screen-printed electrodes (SPE). Sensitivity optimization in terms...
This paper presents the construction of an amperometric biosensor for the highly sensitive detection of the organophosphorus insecticide dichlorvos, based on the inhibition of acetylcholinesterase (AChE). The sensitivity of three AChEs from different sources were tested and compared: AChEs from Electric eel (Ee) and genetically engineered (B394) and wild type (B1) from Drosophila melanogaster (Dm)...
