Disposable paper-based electrochemical biosensor employing g-C 3 N 4 /carbon dots and toll-like receptor for ultrasensitive detection of Gram-negative bacteria
Abstract
. Furthermore, the biosensor demonstrated good stability, reproducibility and ability to attain a satisfactory low LOD in the spiked tap and pond water samples. Moreover, the simple disposability of the paper electrodes lowers the cross-contamination issues and ensures the safety of the environment. Collectively, this work introduces a sustainable, low-cost, and portable biosensing platform that effectively integrates a nanomaterial for enhanced transduction with receptor-based specificity, offering significant potential for early diagnosis of waterborne bacterial contamination and advancing public health protection through POC applications.
