Electrospun biocomposite nanofibers for urea biosensing

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.
