| 英文摘要 | in the present paper the ultrafine and highly dispersed platinum nanoparticles ( average size 3 nm) were used for the construction of a glucose biosensor in a simple method. an excellent response to glucose has been obtained with a high sensitivity (137.7 mu a mm(-1) cm(-2)) and fast response time (5 s). the biosensor showed a detection limit of 5 mm (at the ratio of signal to noise, s/ n = 3) and a linear range form 0.2 to 3.2 mm with a correlation coefficient r = 0.999. the apparent michaelis - menten constant (k(m)) and the maximum current were estimated to be 9.36 and 1.507 ma mm(-1) cm(-2), respectively. in addition, effects of ph value, applied potential and the interferents on the amperometric response of the sensor were investigated and discussed. |
