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,

Emulsion polymerization was optimized to synthesize polystyrene nanoparticles (NPSt) with tailored sizes by adjusting pH and azobisisobutyronitrile (AIBN) content. An NPSt sample prepared 20 mg AIBN at 8 showed the smallest size (88 nm) narrowest distribution (24 nm peak width). XRD patterns indicated semi-crystalline nature for this sample. The involvement of synthesized in nitrogen (N) cycle enhanced our understanding transformations response microbial populations environment. In vitro experiments revealed compatibility tested PGPR strains, no inhibition zones observed. Furthermore, carrot growth soil containing 400 mg/kg significant changes biomass or shoot height compared control soil. This demonstrates samples had negative effects on bacterial communities. Overall, study synthesis NPSt, evaluated environmental impacts cycling PGPR, found toxicity up concentration. insights contribute nanomaterial interactions agricultural systems, highlighting need consider nanoparticles.

Hazards associated with highly dangerous pollutants/contaminants in water, air, and land resources, as well food, are serious threats to public health the environment. Thus, it is imperative detect or decontaminate, risk-control strategies, possible harmful substances sensitively efficiently. In this context, due their capacity be specifically designed for various types of hazardous compounds, synthesis use molecularly imprinted polymers (MIPs) have become widespread. By molecular imprinting, affinity sites complementary shape, size, functionality can created any template molecule. MIPs' unique functions response external factors attracted researchers develop a broad range MIP-based sensors increased sensitivity, specificity, selectivity recognition element toward target compounds. Therefore, paper comprehensively reviews very recent progress MIPs smart polymer applications sensing decontamination compounds (e.g., drugs, explosives, biological chemical agents) fields from 2020 2024, providing rapid tool investigating latest research status.
