Since the 1980s, surface enhanced Raman scattering (SERS) has been used for rapid and sensitive detection of biomolecules. Whether a label-free or labeled assay is adopted, SERS demonstrated low limits in variety biological matrices. However, analysis confined to laboratory due several reasons such as reproducibility scalability, both which have discussed at length literature. Another possible issue with lack widespread adoption that its application point use (POU) testing only now being fully explored advent portable spectrometers. Researchers are investigating how can be output on POU platforms lateral flow assays, wearable sensors, volatile organic compound (VOC) human healthcare monitoring, favorable results rival gold standard approaches. obstacle faces interpretation wealth information obtained from platform. To combat this, machine learning shown provide quick accurate generated data, leading discrimination many clinically relevant This review will discuss advancements combined strength bring produce powerful platform monitoring.

Chloramphenicol (CAP), an aminoalcohol antibiotic, exerts its action on bacterial ribosomes, thereby obstructing protein synthesis. However, the use of CAP in husbandry may lead to excessive accumulation animal-derived food products. This presents potential risks consumer health. study developed a novel dual-amplification fluorescence detection method by integrating enzyme-assisted solid-phase microextraction (SPME) with Fe3O4@Au NP-based DNA nanowalker for food. The combination quartz rod-based SPME biosensor and effectively eliminated matrix interference, enabling conversion enhancement signals through two cyclic amplification processes. strategy demonstrated high sensitivity limit 28.1 aM as well wide linear range from 0.1 fM 1 nM (with R2 > 0.99). also demonstrates robust stability accuracy detecting trace amounts both authentic prepared positive samples.
