摘要：
Escherichia coli (E.C.) bacterium detection in drinking water is a global issue since it can cause dangerous illnesses in the human body. In this work, an SPRN biosensor with prism, silver, MXene, and analyte is suggested theoretically for the rapid and accurate identification of E.C. in drinking water. Many different prisms are investigated: BK7, N-FK51A, SF10, and 2S2G. It is demonstrated that the structure with the prism N-FK51A corresponds to the highest sensitivity; hence, it is taken into consideration for additional studies. Since an MXene layer has a stronger light-matter interaction and a larger surface area, it enhances the surface-biomolecules adsorption. To increase sensor sensitivity, the thickness of the silver layer and the number of MXene layers are adjusted. With a bi-layer of MXene, and 50 nm silver, the SPRN biosensor can acquired a sensitivity of about 212.54 degree/RIU. We believe the suggested sensor will be beneficial for application in the field of microbe identification and has a simple construction to make fabrication easier.
