Pathogens and their metabolites in food present significant risks to both human health economic development. Rising living standards increasing awareness of safety have driven the demand for sensitive rapid detection methods. Lanthanide-doped upconversion nanoparticles (UCNPs), with exceptional optical properties, emerged as a promising platform developing biosensors detect pathogenic bacteria metabolites. The integration UCNPs point-of-care testing (POCT) has garnered considerable attention its portability immediacy, highlighting future biosensing, particularly applications requiring quick accurate diagnostics. This review explores recognition elements design principles commonly used UCNP-based examines various applications, including lateral flow assays, microfluidic systems, photoelectrochemical devices, smartphone-integrated platforms. Despite advancements, challenges remain applicability commercialization biosensing technology. Future research should focus on enhancing sensitivity specificity, scalable cost-effective production methods, integrating advanced digital technologies enable broader adoption. Addressing these challenges, establishing regulatory frameworks, considering sustainability will be crucial fully realizing potential biosensors.

ABSTRACT The issue of pharmaceutical residues in the environment has become increasingly severe, with detection sulfonamide antibiotics emerging as a research hotspot environmental monitoring. Herein, we present method for detecting sulfadiazine based on silicon quantum dots (SiQDs)‐based fluorescent molecularly imprinted sensor. SiQDs, synthesized using an aqueous phase method, exhibit remarkable properties, such broad excitation spectrum, tunable emission wavelengths, and high fluorescence stability, offering significant advantages detection. By integrating amino‐functionalized silica nanospheres (NH 2 ‐SiO ) tetraethyl orthosilicate, SiQDs were surface‐functionalized to construct SiQDs@NH @MIPs composite materials. modified polymers not only exhibited selectivity affinity target molecule SDZ, but also demonstrated excellent stability resistance interference complex environments. Experimental results revealed that sensor displayed strong linear correlation within concentration range 40–100 μmol·L −1 , limit 0.036 ng·mL demonstrating sensitivity selectivity. In real sample applications, recovery rate ranged from 97.88% 100.74%, relative standard deviation less than 5.37%. These findings emphasize wide potential applications this sensor, especially water quality monitoring, protection,

Опубликована: Май 7, 2025

The rapid and cost-effective detection of food contaminants such as toxins pathogens is a major challenge key concern for safety. To this end, innovative, fast, cost-effective, easy-to-use sensors must be developed at the point where produced, distributed, consumed. Therefore, timely response to can improve human health reduce economic burden. However, affordable sensor technologies with specificity, sensitivity, speed are required, which used by non-specialized personnel enable high throughput analysis. In respect, advances in development nanoparticle-based sensors, i.e., nanosensors, have shown potential provide much-anticipated versatile sensors. addition, multiplex detection, ability detect multiple targets simultaneously, another strategy facilitated will further improvements performance that important developing effective monitoring. This review summarizes nanosensors sensing samples respect hazardous contaminates reported over past few years. special attention paid providing reader promising design principles current sensitivity selectivity practical requirements, thereby inspiring new ideas advanced systems.
