An optical biosensor is a specialized analytical device that utilizes the principles of optics and light in bimolecular processes. Localized surface plasmon resonance (LSPR) phenomenon realm nanophotonics occurs when metallic nanoparticles (NPs) or nanostructures interact with incident light. Conversely, surface-enhanced Raman spectroscopy (SERS) an influential technique based on scattering, wherein it amplifies signals molecules they are situated near specific specially designed nanostructures. A detailed exploration recent ground-breaking developments biosensors employing LSPR SERS technologies has been thoroughly discussed along their underlying working mechanisms. chip created, featuring high-density deposition gold (AuNPs) under varying ligand concentration reaction duration substrate. ordinary description, visual illustration, provided for concepts such as sensogram, refractive index shift, (SPR), evanescent field, Rayleigh well electromagnetic enhancement chemical enhancement. both have advantages disadvantages, but widely used some over LSPR, like specificity, high sensitivity, multiplexing, versatility different fields.

Antimicrobial‐resistant Escherichia coli , especially those belonging to the serotype O157, are increasingly linked foodborne diseases with significant fatality rates worldwide. The food and medical industries have focused on E. O157:H7 due its ability produce toxins coupled low infectious dose. aim of this study was assess virulome, resistome, pathogenicity using whole genome sequencing. Three previously isolated strains from cattle feces were subjected sizes all three 5,117,276 bp, 5,039,443 5,034,351 bp. C + G contents 50.22%, 50.53%, 50.54%, while number contigs 110, 43, 42, respectively, for J32, J57, J69. Several virulence determinants (hemorrhagic pilus (HCP), eaeA, hemolysin, etc.) found in genomes these isolates. In addition, antibiotic resistance genes conferring aminoglycosides, tetracyclines, macrolides, fluoroquinolones, penams, carbapenems, cephalosporins, cephamycin, rifamycin, phenicols, monobactams, nitroimidazole genomes. Interestingly, isolates also harbored encoding disinfectants antiseptics, indicating their concern production sectors. This highlights public health concerns isolates, need constant surveillance.

Rapid and accurate detection of DNA from disease-causing pathogens is essential for controlling the spread infections administering timely treatments. While traditional molecular diagnostics techniques like PCR are highly sensitive, they include nucleic acid amplification many need to be performed in centralized laboratories, limiting their utility point-of-care settings. Recent advances CRISPR-based (CRISPR-Dx) have demonstrated potential specific detection, but sensitivity often constrained by slow trans-cleavage activity Cas enzymes, necessitating preamplification target acids. In this study, we present a CRISPR-Cascade assay that overcomes these limitations integrating positive feedback loop enables amplification-free pathogenic at atto-molar levels achieves signal-to-noise ratio greater than 1.3 within just 10 min. The versatility through bloodstream infection pathogens, including Methicillin-Sensitive Staphylococcus aureus (MSSA), Methicillin-Resistant (MRSA), Escherichia coli , Hepatitis B Virus (HBV) spiked whole blood samples. Additionally, introduce multiplexing OR-function logic gate, further enhancing rapid clinical Our findings highlight ability provide sensitive paving way advanced applications beyond.
