Nano biosensors have emerged as powerful analytical tools at the forefront of biosensing technology, offering unparalleled sensitivity and specificity in detecting biochemical substances at nanoscales. Comprising a bio-receptor sensing element and a transducer component, nano biosensors convert biological and biochemical signals into quantifiable physical signals using optical, electronic, thermal, or magnetic methods. The effectiveness of these sensors is contingent upon the precise attachment of the biological component to the transducer, ensuring stability and selectivity in analyte detection. By incorporating nanomaterials, nano biosensors enhance stability, sensitivity, and catalytic activity, revolutionizing biosensing capabilities. This article elucidates the working principles, classification, and applications of nano biosensors, emphasizing their pivotal role in diverse fields such as agriculture and biomedical diagnostics. From detecting soil pathogens to diagnosing severe diseases like cancer and diabetes, nano biosensors offer unprecedented opportunities for precise and efficient detection, marking a significant advancement in biosensor technology.
