Abstract: The present invention relates to a biosensor chip (100) for the detection of toxins in food and a method thereof. The biosensor chip (100) comprises a flexible substrate (102); a conductive layer (104) deposited on the flexible substrate (102); a bio-receptor (106) coated on the conductive layer (104) through a cross-linker (110); an analyzer (112) connected to the biosensor chip; and an operating device (114) to view the output. The length of the conductive layer (electrode) (104) is in range of 0.4 cm to 4 cm; angle between the two arms (116, 118) of the conductive layer (104) is in the range of 35°-65°; width of the conductive layer (104) is in range of 100 ?m-1000 ?m; and width between the two consecutive conductive layers (104) is in range of 100 ?m-1000 ?m, ensuring easy deployment of the biosensor chip (100) for rapid screening and quantification of toxins in food products.

Abstract: The sensor chips, processes and devices enable ultra-sensitive detection/determination, evaluation and quantitative measurement of analytes and are useful for high throughput and miniaturized assays, which enable a user to perform multiple, accurate, experiments in parallel with minimum amount of reagents resulting in low waste generation. The method enables screening of fluid samples to meet regulatory standards. The device comprises a pitted chip having a silicon-based substrate, optionally provided with an integrated heating element, a biosensor and a receptor immobilized on a cross linking element fixed to an inert metal layer in the chip. The analyte is detected up to 5 parts per trillion of the fluid sample and quantitatively measured up to 10 parts per trillion of the fluid sample by the device of the present disclosure.
