Food is a necessary source of energy, but it also serves as pathway for transmitting infectious pathogens, making food safety matter great concern. Rapid, accurate, and specific detection methods foodborne viruses are crucial. Surface-Enhanced Raman Scattering (SERS), due to its superior sensitivity characteristic fingerprint spectra, holds enormous potential. However, the limitations SERS, requires conditions achieve specificity. In order enhance specificity accuracy nucleic acid based on we have developed CRISPR-Cas12a-mediated SERS technique identify target DNA, harnessing targeting recognition capability CRISPR-Cas12a ultra-sensitive tags successfully addressing SERS' lack capability. This system includes gold/nickel foam substrate (Au-NFs) reporter (ssDNA-ROX). The phenomenon colloidal gold/silver nano-aggregation magnesium ions, which commonly encountered in CRISPR-SERS, was simultaneously solved using AuNFs. qualitative quantitative analysis DNA drinking water performed by monitoring intensity change ROX molecules. results showed that sensor detected within 30 min limit (LOD) 8.23 fM. expected become one alternative rapid high

CRISPR/Cas systems have become integral parts of nucleic acid detection apparatus and biosensors. Various such as CRISPR/Cas9, CRISPR/Cas12, CRISPR/Cas13, CRISPR/Cas14 CRISPR/Cas3 utilize different mechanisms to detect or differentiate biological activities nucleotide sequences. Usually, CRISPR/Cas-based are combined with polymerase chain reaction, loop-mediated isothermal amplification, recombinase amplification transcriptional technologies for effective diagnostics. Premised on these, many biosensors been developed acids viral bacterial pathogens in clinical samples, well other applications life sciences including biosecurity, food safety environmental assessment. Additionally, showed better specificity compared molecular diagnostic methods. In this review, we give an overview various methods highlight some advances their development components. We also discourse operational challenges advantages disadvantages systems. Finally, important considerations offered the improvement testing.

Rapid and accurate diagnosis is crucial for managing the global health threat posed by multidrug-resistant bacterial infections; however, current methods have limitations in either being time-consuming, labor-intensive, or requiring instruments with high costs. Addressing these challenges, we introduce a wireless electrochemical sensor integrating CRISPR/Cas system electroconductive polymer dot (PD) nanoparticles to rapidly detect pathogens from human sputum. To enhance properties, synthesized copper-ion-immobilized PD (PD-Cu), followed conjugation of deactivated Cas9 protein (dCas9) onto PD-Cu-coated Si electrodes generate dCas9-PD-Cu sensor. The integrated isothermal amplification can specifically target nucleic acids bacteria, such as antibiotic resistance genes kpc-2 mecA. exhibits sensitivity, allowing detection ∼54 femtograms acids, based on measuring changes resistivity through capture dCas9. Furthermore, sensing platform was established using Bluetooth module microcontroller unit smartphone. We demonstrate feasibility diagnosing pneumonia patients' sputum samples, achieving 92% accuracy. study presents versatile biosensor that overcome conventional diagnostics clinic.
