Ultrasensitive detection of E. coli using bioinspired based platform

Bacterial infections are a leading cause of mortality worldwide, underscoring the urgent need for effective detection methods. This study introduces a novel approach that combines surface-enhanced Raman spectroscopy (SERS) with an electro-optic technique for bacterial detection. The method utilizes a metal-semiconductor substrate that, when activated by an external electric field, significantly amplifies the SERS signal intensity. We validated this approach through a proof-of-concept study, demonstrating that the SERS signal of Gram-negative
