TLDR
In this paper, the authors presented an innovative technique for enzyme immobilization using nanocomposite fibers of urease and polyvinylpyrrolidone (PVP).Abstract:
Urease E.C.3.5.1.5 acts as a catalyst in the hydrolysis of urea to ammonia and carbon dioxide. Presence of this enzyme can increase the rate of reaction by 10 14 . Urea levels are vital in medical diagnosis, environmental and bioindustrial analysis. This paper presents an innovative technique for enzyme immobilization. Nanocomposite fibers of urease and polyvinylpyrrolidone (PVP) were prepared by the electrospinning technique. The non-woven mat formed has potential as a urea biosensor. Its advancements over prior technology are faster response time, sensitivity to lower concentrations of urea, and a more versatile design.read more
