Published: Jan. 26, 2024

Abstract Highly selective and sensitive quantitative detection of ofloxacin (OFX) at ultralow concentrations in aqueous media development new afterglow materials remains a challenge. Herein, 2D water‐stable lanthanide metal–organic framework (NIIC‐2‐Tb) is proposed, which exhibits high selectivity towards OFX through the luminescence quenching with lowest limit (1.1 × 10 −9 M ) reported to date fast response within 6 s. In addition, luminescent by NIIC‐2‐Tb not affected typical components blood plasma urine. The excellent sensing effect further utilized prepare composite functional carrageenan hydrogel material for rapid meat real time first discovery impressive MOF‐based hydrogels. This study only presents novel Ln‐MOF Ln‐MOF‐based films OFX, but also demonstrates color‐tunable afterglow, expands application anti‐counterfeiting.

Published: April 24, 2024

Abstract The development of novel photosensitizers (PSs) with aggregation‐induced emission (AIE) properties has emerged as a crucial advancement in the field photodynamic therapy (PDT). However, versatile applications AIE PSs are limited by low encapsulation efficiency and inadequate target tissue permeability. Biomimetic technology stands out promising strategy to overcome these challenges, aiming enhance tumor penetration efficacy, their association antitumor immune responses. In this review, recent advancements biomimetic for PDT immunotherapy summarized. We start introducing strategies involving based on cell membranes extracellular vesicles combined application immunotherapy. then discuss preparation nanoparticles. Finally, we briefly outline challenges prospects associated PSs.

Machine Learning-Assisted Eu(III)-Functionalized HOF-on-HOF Composite-Based Sensor Platform for Precise and Visual Identification of Multiple Pesticides

Analytical Chemistry, Journal Year: 2024, Volume and Issue: 96(35), P. 14248 - 14256

Published: Aug. 21, 2024

Precise and rapid identification of pesticides is crucial to ensure a green environment, food safety, human health. However, complex sample environments often hinder precise identification, especially for simultaneous differentiation multiple pesticides. Herein, we first synthesize Eu(III)-functionalized HOF-on-HOF composite (Eu@PFC-1@MA-TPA) then utilize principal component analysis (PCA) machine learning (ML) algorithm achieve the 2,6-dichloro-4-nitroaniline (DCN) thiabendazole (TBZ) their mixtures. Eu@PFC-1@MA-TPA displays high quantitative ability, which can distinguish single DCN TBZ as low 1 μM mixtures at 5 through PCA. In addition, hydrogel film Eu@PFC-1@MA-TPA/AG fabricated monitor in drinking water, tap river apple juice with sensitivity. Furthermore, based on obvious fluorescence color variance pesticides, achieves visual situ imaging detection More importantly, construct an intelligent artificial vision platform integrating DenseNet algorithm, identify concentrations types within s over 98% accuracy. This work develops method combining visualized sensor ML algorithm.
