An acetylcholinesterase (AChE) purified from maize seedlings was immobilized covalently onto iron oxide nanoparticles (Fe(3)O(4)NP) and carboxylated multi walled carbon nanotubes (c-MWCNT) modified… Expand
Occurrence of an oxalate oxidase in Sorghum leaves
Abstract An oxalate oxidase found in the 15 000 g supernatant of 10-day-old sorghum leaves exhibited a pH optimum of 5 and a temperature optimum of 45° and was unaffected by Na + . The enzyme… Expand
A method for determination of xanthine in meat by amperometric biosensor based on silver nanoparticles/cysteine modified Au electrode
Abstract A method is described for construction of an amperometric xanthine biosensor based on covalent Immobilization of xanthine oxidase (XOD) onto citrate capped silver nanoparticles deposited on… Expand
Construction of an amperometric enzymic sensor for triglyceride determination
Abstract An amperometric enzyme sensor for determination of triglycerides (TGs) was constructed by mounting cellulose acetate (CA) membrane-bound commercial lipase (E.C.22.214.171.124), glycerol kinase (GK)… Expand
