Abstract: A nicotinic acid sensor based on molecular imprinting technology was fabricated by in situ photopolymerization. After the template was extracted, incubation and measurements were carried out directly. The response of the sensor was linear, with nicotinic acid concentrations in the range of 0.05 - 5mmol/L. Due to the imprinting effect, the sensor exhibited high selectivity for the template compared to closely related analogs such as benzoic acid and isonicotinic acid. Scanning electron microscope images showed no obvious difference between the imprinted electrode surface and the non-imprinted one. This sensor was also used to determine nicotinamide in a Wahaha soft drink sample
