Summary: We report a selective and precise colorimetric detection method for lead (Pb) heavy metal in water, utilizing the aggregation and self-assembly mechanisms of glutathione (GSH)-functionalized gold nanoparticles (GNPs). The aggregation of GNPs in the presence of Pb2+ due to the chelation of GSH ligands leads to a substantial shift in plasmon wavelength, causing a red-to-blue colorimetric or visual change, enabling instant determination of lead content in water.

Summary: A novel colorimetric/fluorescent probe (AgNPs-GSH-Rh6G2) was prepared by linking silver nanoparticles (AgNPs) with rhodamine 6G derivative (Rh6G2) using glutathione (GSH) as a linker molecule. The probe exhibited significant fluorescence change and colorimetric response upon addition of copper ions. A colorimetric/fluorescence dual-mode detection method was developed based on this phenomenon to selectively detect copper ions. The probe showed good sensitivity with linear ranges of 0.10-0.45 mM for fluorescence detection and 0.15-0.65 mM for colorimetric detection, and the detection limits were 0.18 μM and 24.90 μM, respectively. The dual-mode probe also demonstrated satisfactory results in detecting copper ions in sediment samples.

Summary: This study investigated the colorimetric detection of four antibiotics used in cattle in raw milk using aptamer-conjugated gold nanoparticles. The influence of milk matrix on the activity of the nanoaptasensors was analyzed and a preanalytical strategy was developed for the detection of antibiotic-contaminated raw milk samples. The results showed that the colorimetric signals could be detected in spiked samples at concentrations as low as 0.25-fold the maximum residue limits (MRLs) according to European and Chilean legislation. Overall, this methodology holds potential for the analysis of antibiotic residues in raw milk.

Summary: In this study, a direct colorimetric technique using functionalized 18 beta-glycyrrhetinic acid peptide silver nanoparticles (GAP-AgNPs) was developed for the detection of Ba2+ ions in laboratory tap and river water. The GAP-AgNPs showed selectivity and sensitivity towards Ba2+, leading to a noticeable color change. The nanoparticles exhibited stability at high temperatures, different electrolyte concentrations, and pH values. The findings suggest that GAP-AgNPs can serve as a selective and sensitive sensing probe for Ba2+ in various water samples.
