Given that intricate toxicological profiles exist among different antibiotics and pose serious threats to the environment human health, synchronous analysis of multiple residues becomes crucial. Sensor arrays show potential achieve above purpose, but it is challenging develop easy-to-use high-sensitivity tools because state-of-the-art often require more than one recognition unit are monosignal dependent. Here we exquisitely designed a fluorescent nanoprobe (2-aminoterephthalic acid-anchored CdTe quantum dots with Eu3+ coordination, CdTe-ATPA-Eu3+) featuring triple emissions at same excitation as only element fabricate luminescent sensor array ratiometric calculations for identifying antibiotics. By taking tetracycline, chlortetracycline, doxycycline, oxytetracycline, penicillin G, sulfamethoxazole models, six species exhibited distinguishable motivation or/and quenching impacts on three CdTe-ATPA-Eu3+, which were employed indicators perform logical operation further combined pattern multitarget determination. Evidently, such design exhibits two advances: (1) triple-emission probe sole receptor requiring neither internal nor external adjustments, fabricated acts an extremely facile tool multianalyte detection; (2) offer excellent sensitivity reliability high-performance Consequently, accurate identification quantification individual their combinations various levels verified in both laboratory practical matrices. Our work provides new simultaneously detecting antibiotics, will inspire development advanced analysis.

Abstract As an ideal transition metal oxide, Co 3 O 4 is a P-type semiconductor with excellent electrical conductivity, non-toxicity and low cost. This work reports the successful construction of materials derived from metal-organic frameworks (MOFs) using surfactant micelle template-solvothermal method. The modified electrodes are investigated for their ability to electrochemically detect Pb 2+ Cu in aqueous environments. By adjusting mass ratios alkaline modifiers, morphological microstructures -X exhibit distinctive microspheres composed fiber stacks rods. results indicate that -1(NH F/CO(NH 2 ) = 1:0) has microsphere structure stacked fibers, unlike other two materials. -1/GCE used as active material electrode, it shows largest peak response currents , efficiently detects environment individually simultaneously. linear range simultaneous detection 0.5–1.5 μM, limits (LOD, S/N 3) 9.77 nM 14.97 nM, respectively. exhibits favorable electrochemical response, via -1 fibers. enhances number adsorption sites on material, thereby facilitating heavy ions (HMIs). presence oxygen vacancies (O V can also facilitate ions. electrode anti-interference ability, stability, repeatability. great practical significance detecting real water samples provides new approach developing high-performance oxide sensors MOFs.

Abstract Low‐cost, reliable, and efficient biosensors are crucial in detecting residual heavy metal ions (HMIs) food products. At present, based on distance‐induced localized surface plasmon resonance of noble nanoparticles, enzyme‐mimetic reaction nanozymes, chelation chelators, the constructed optical sensors have attracted wide attention HMIs detection. Besides, enrichment signal amplification strategy nanomaterials construction electrochemical aptamer sensing platforms, developed overcome plague low sensitivity, poor selectivity, inability multiplexed detection strategy. Moreover, along with an in‐depth discussion these different types biosensors, a detailed overview design application innovative devices principles was provided, including microfluidic systems, hydrogel‐based test strip technologies. Finally, challenges that hinder commercial also been mentioned. Overall, this review aims to establish theoretical foundation for developing accurate reliable technologies HMIs, thereby promoting widespread food.
