一般說明

Escherichia coli (E.coli) is a non-spore forming, Gram-negative, rod-shaped facultative anerobe, which is found in the human gastrointestinal tract. It belongs to the family of Enterobacteriaceae. E.coli is chemoorganotrophic and grows at 37°C. Pathogenic E.coli strains is associated with diarrhea, septicemia, meningitis and urinary tract infections. It inhibits the colonization of the gut by harmful bacteria. E.coli acts as an indicator of fecal contamination.

其他說明

A mutant which is rich in alkaline phosphatase.

We are reporting an original supramolecular architecture based on a rationally designed new nanohybrid with enhanced peroxidase-like activity and site-specific biorecognition properties using avidin-functionalized multi-walled carbon nanotubes (MWCNTs-Av) and Ru nanoparticles (RuNPs). The nanohybrid-electrochemical interface was obtained by drop-coating of

We develop a low-background electrochemical biosensor for one-step detection of uracil DNA glycosylase (UDG) based on the host-guest interaction and iron-embedded nitrogen-rich carbon nanotube (Fe-N-C) that mimics enzyme-mediated electrocatalysis to achieve signal amplification. In this work, Fe-N-C is initially immobilized

Owing to their high surface area, stability, and functional groups on the surface, iron oxide hydroxide nanoparticles have attracted attention as enzymatic support. In this work, a chemometric approach was performed, aiming at the optimization of the horseradish peroxidase (HRP)
