  6. Recent Advances in Biosensors for Detection of Chemical Contaminants in Food — a Review

    • Food Analytical Methods
    • In recent decades safety of food has played a pivotal role from raw material till it reaches the consumer. The food consumed may contain unwanted contaminants, which may impose severe health implications on the consumers. Instrumental techniques like HPLC, GCMS, LCMS, AAS, FTIR, and NIRS detect the contaminants, but the need for low cost, continuous, specific, real-time, and rapid contaminant detection method is required. To meet these essentials, a biosensor stands as a powerful tool.
