Effective bacterial detection is crucial for health diagnostics, particularly the of pathogenic species like Escherichia coli (E. coli), which responsible up to 90% urinary tract infections (UTIs), especially crucial. Current methods are time-consuming, often delaying diagnosis and treatment. This study introduces an innovative approach rapid E. using porous silicon (PSi) substrates combined with Surface Imprinted Polymers (SIPs) photoluminescence-based (PL-based) detection. The PSi/SIP offer high sensitivity, selectivity, a low limit (LOD) without need natural recognition elements. These substrates, fabricated via metal-assisted chemical etching (MACE) PDMS-based imprinting, demonstrate reliable repeatability fast Real-time experiments in phosphate-buffered saline (PBS) urine showed consistent stair-like quenching PL signal increasing concentrations, achieving theoretical LODs approximately 13 ± 2 CFU/mL PBS 17 3 urine. exhibited excellent differentiating from other such as Cronobacter sakazakii (C. sakazakii) Listeria monocytogenes. sensitivity reproducibility along ease use capabilities resulting sensor, highlight potential this novel platform point-of-care (PoC) applications clinical diagnostics.

This review explores the development, technological foundations, and applications of biosensor technologies across various fields, such as medicine for disease diagnosis monitoring, food industry. However, primary focus is on their use in detecting contaminants pathogens, well environmental monitoring water quality assessment. The classifies different types biosensors based bioreceptor transducer, highlighting how they are specifically designed detection emerging (ECs) pathogens water. Key innovations this technology critically examined, including advanced techniques systematic evolution ligands by exponential enrichment (SELEX), molecularly imprinted polymers (MIPs), self-assembled monolayers (SAMs), which enable fabrication sensors with improved sensitivity selectivity. Additionally, integration microfluidic systems into analyzed, demonstrating significant enhancements performance speed. Through these advancements, work emphasizes fundamental role key tools safeguarding public health preserving integrity.
