Abstract
Based on surface plasma resonance (SPR), a novel optical chemical sensor was developed. Traditionally, wavelength modulation SPR sensing method adapted tungsten lamp as the light source with an expensive and complicated apparatus. The device presented here is a relatively simple and inexpensive one. It was designed using a white LED with a 5 V battery as the light source. The percentage bound of 8 antibiotics with BSA was studied by this setup. The results were compared with the reliable percentage bound data obtained by standard equilibrium dialysis and a relative good agreement was achieved.
