Abstract
The invention provides a high-sensitivity non-enzymatic glucose sensor and a preparation method thereof. The high-sensitivity non-enzymatic glucose sensor is formed by sintering a gold and bovine serum albumin film on the surface of fluorine-doped tin oxide conductive glass. The specific operation comprises the steps that a chloroauric acid solution is taken and added into a bovine serum albumin solution, the pH value is adjusted to be alkaline after stirring, ascorbic acid is added, centrifugation and washing are conducted after sufficient reaction, and obtained precipitates are dispersed in deionized water and placed in a low-temperature environment for aging for use. Taking the fully aged prepared solution, dropwise adding the fully aged prepared solution on fluorine-doped tin oxide conductive glass to form round liquid drops, drying, sintering at high temperature, and finally naturally cooling to room temperature to obtain the high-sensitivity non-enzymatic glucose sensor. The sensor has the advantages of being large in detection linear range, high in sensitivity, low in detection limit, good in stability and the like.
