BIOSENSOR DEVICE FOR THE DETERMINATION OF CAFFEINE IN FOOD SAMPLES

摘要

The development and application of new caffeine detection methods remains an active area of investigation, particularly in food and clinical chemistry. Significant research and development activity has been devoted to preparing compact analytical devices comprising a bioactive sensing element integrated with a suitable transuding system, also known as biosensors, for determination of various inorganic, organic and biological substances. The main advantages of these devices are their specificity, sensitivity and simple preparation, and the fact that no other reagents besides a buffer and a standard are usually required. Keeping all the above factors in view work was done to develop a biosensor for the estimation of caffeine in food and beverage samples.
