Preparation and electrochemical behavior of L-glutamate electrochemical biosensor.
Copyright policy )Preparation and electrochemical behavior of L-glutamate electrochemical biosensor.
Using the nano-porous pseudo carbon paste electrode (Nano-PPCPE) as the working electrode, mixing L-glutamate oxidase (L-GLOD), catalase (Cat) and bovine serum albumin (BSA) with phosphate buffer (PB, pH = 7.4), followed by cross-linking with glutaraldehyde, a novel L-glutamate electrochemical biosensor was successfully formed. It was demonstrated that the modified nano-PPCPE exhibits a high selectivity and sensitivity in comparison with the modified CPE. The L-glutamate biosensor showed a linear range from 5 x 10(-7) M to 1 x 10(-5) M with the detection limit of 2.5 x 10(-7) M.
