Free and sol-gel immobilized alkaline phosphatase-based biosensor for the determination of pesticides and inorganic compounds
Alkaline-phosphatase (ALP) catalyses the hydrolysis of 1-naphthyl phosphate to fluorescent 1-naphthol ( λex = 346 nm, λem = 463 nm). This enzymatic reaction was investigated in presence ofExpand

P-phenol derivatives as enhancers of the chemiluminescent luminol-horseradish peroxidase-H2O2 reaction: substituent effects
Abstract We studied the substituent effects of ten p-phenol derivatives and aniline on the chemiluminescence from the luminol-horseradish peroxidase-H2O2 system. The enhancer effects of someExpand

Horseradish peroxidase sol-gel immobilized for chemiluminescence measurements of alkaline-phosphatase activity
Naphthyl phosphate is a pro-enhancer of the luminol-H2O2-horseradish peroxidase reaction. Alkaline-phosphatase hydrolyses the phosphate group and produces 2-naphthol. This compound is an enhancer ofExpand
