Paraquat (PQ) is a potent and widely utilized herbicide known for its effectiveness in controlling a broad spectrum of weeds. Its chemical properties make it an invaluable tool in agriculture, where it helps maintain crop yields and manage invasive plant species. However, despite its benefits in weed management, PQ poses significant risks due to its severe toxicity, which affects multiple organ systems in both humans and animals. The dual nature of PQ, as both a valuable agricultural chemical and a hazardous toxicant, necessitates a comprehensive understanding of its toxicological impacts and the development of effective detection and development strategies. This review aims to provide a comprehensive overview of PQ-induced toxicities, including neurotoxicity, lung toxicity, liver toxicity, kidney toxicity, and immunotoxicity. By synthesizing current knowledge on PQ health impacts, highlighting epidemiological trends, and exploring recent advancements in colorimetric and fluorimetric detection methods, this review seeks to contribute to the development of strategies for improving public health outcomes and enhancing our ability to manage the risks associated with PQ exposure. Addressing PQ toxicity through a multidisciplinary approach, incorporating toxicological, epidemiological, and technological perspectives, is essential for safeguarding health and promoting effective interventions.

Water-soluble and biocompatible protein carbon dots (P-CDs) were simply prepared from egg white by a rapid one-step neutralization heat reaction. Unexpectedly, the thus-fabricated P-CDs could present excitation-dependent tunable fluorescence that could be quenched specifically by Fe and Fe ions with obvious color changes. A high-throughput fluorimetric platform was thereby developed by coating the P-CDs onto a capillary array for detection of total iron ions in fish blood samples, with a linear concentration range of 0.

Oxazolidine is a new category of stimuli-chromic compounds that has unique intelligent behaviors such as halochromism, hydrochromism, solvatochromism, and ionochromism, all of which have potential applications for designing and constructing chemosensors by using functionalized-polymer nanocarriers. Here, the poly(MMA--HEMA) based nanoparticles were synthesized by emulsion copolymerizing methyl methacrylate (MMA) and 2-hydroxyethyl methacrylate (HEMA) in different copolymer compositions. The poly(MMA--HEMA) based nanoparticles were modified physically with tertiary amine-functionalized oxazolidine (as an intelligent pH-responsive organic dye) to prepare halochromic latex nanoparticles.

Herein, we report the synthesis of copillar[5]arene-based pyrene Schiff base 1 and its characterization by using 1H, 13C NMR, FT-IR and mass spectrometry. UV-vis absorption, steady-state fluorescence and time-resolved fluorescence are done to elucidate the photophysical behaviors of 1. To understand the electronic structure of 1, density functional theory (DFT) calculations are performed.

Hydrazine (NH) and hydrogen sulfide (HS) are environmental contaminants that adversely affect human health. Fluorescence-based detection methods for these analytes utilize their nucleophilicity and reducing ability. Therefore, fluorescent sensors capable of detecting and distinguishing hydrazine and HS are highly beneficial.

Mercury (II) ions (Hg) are a significant source of heavy metal contamination in groundwater, posing a serious threat to human health and the environment. Therefore, there is an urgent need for the development of a new detection technique with high sensitivity for monitoring Hg in contaminated groundwater. Here, we developed a signal amplifying MOF-based probe (NXS@ZIF-8) for on-site and ultrasensitive dual-channel portable detection of Hg in groundwater.
