results low concentrations of agnps and short incubation times can have the maximum positive impact on the peroxidase activity, and in the present study the highest activity was seen at a concentration of 40 mg/l and two hours of incubation time. conclusions this study suggests that changes of enzyme activity can occur as a result of the effect of silver nanoparticles on enzyme conformation, in...

The considerations are discussed that make continuous monitoring of reaction-progress curves superior to fixed-incubation methods in the determination of enzyme activity. Provided that they are used with caution and their limitations are appreciated, fixedincubation methods continue to fulfill a useful, though diminishing, role in clinical enzymology because of their adaptability to existing pa...
