Continuous accumulation of Al3+ in the human body and unintended leakage UO22+ have posed a great threat to health global environment; thus searching an efficient probe for detection is importance. Herein, we designed synthesized two hydrolytically stable Eu3+- Tb3+-functionalized MOF materials Eu@MOF-808-TDA Tb@MOF-808-TDA via thiodiglycolic acid (TDA) intermediates by postsynthetic modification method. Among them, was applied construct numerical recognition systems multiples three four combination fluorescent signals, hierarchical cluster analysis, logical gates. In addition, exhibits good selectivity sensitivity UO22+. The limit calculated be 0.085 ppm 0.082 aqueous solutions, which lower than or close that latest reported Ln-MOFs. Moreover, shows excellent hydrolytic stability luminescence pH range 4-11, further providing solid evidence practical application Tb@MOF-808-TDA. More importantly, mixed matrix hydrogel PVA-Tb@MOF-808-TDA prepared achieve visual Al3+, broadens potential real-world sensing applications.

Most of the metal ions are carcinogens and lead to serious health concerns by producing free radicals. Contamination drinking water sources with heavy metals has a harmful impact on environment human health. The most commonly used zinc (Zn), copper (Cu), (Pb), tin (Sn), cadmium (Cd), chromium (Cr), iron (Fe), mercury (Hg), etc. easily absorbed living things via spread throughout food chain, posing threat humans, plants, animals. Hence, fast accurate detection become critical issue. Among various arsenic, cadmium, lead, considered be highly toxic. To detect these ions, colorometric, fluorometric electrochemical biosensors interfaces such as nanomaterials like especially nanoparticles including gold, silver, have been developed. these, promising, owing their strong adsorption, electron transfer kinetics, biocompatibility, which very apt for biosensing applications. coupling techniques enhanced sensitivity, limit detection, robustness sensors. In this review, reduction toxicity or removal toxic from summarized. Also, different types sensors employed in highlighted.

Gold nanoparticles (AuNPs) were prepared by using a green approach that employed orange (citrus sinensis) peel water extract (OPE) as reducing agent. In this case, the organic compounds present in able to reduce Au(III) Au(0) and, at same time, act capping agent, functionalizing surface of AuNPs, stabilizing them solution. This “green” valorizes waste resourceful material and makes synthetic process AuNPs more environmentally sustainable, safe, economically feasible than traditional methods. The obtained gold (AuNPs@OPE) characterized FT–IR, DLS, SEM analysis, UV–Vis spectroscopy; latter showed characteristic plasmon resonance (SPR) band 530 nm, typical spherical nanoparticles. AuNPs@OPE then tested colorimetric sensors for heavy metals water, showing an affinity selectivity toward Pb2+. fact, presence Pb2+, added cation favors aggregation process, form clusters due interactions between Pb2+ carboxyl/hydroxyl groups on AuNPs@OPE, increasing size nanostructure. is accompanied change color from pink violet, with formation second, new SPR band, higher wavelength, relative aggregate formation. assay was different times addition ions LOD values 13.31 µM 0.05 after 15 min 90 min, respectively. proposed also analyzing drinking samples demonstrating reliability use real samples.
