are ubiquitous algae and occasional pathogens of humans and animals. While rare, the infection is often fatal and treatment options are limited to antifungals with low efficiency. Here, using growth curve assays, we demonstrate that five pathogenic species of () were fully inhibited by 50-100 μg/mL of herbicide glyphosate, suggesting novel pathways that can be considered for anti-algal drug development.

People are continually and simultaneously exposed to various non-persistent pesticides as these chemicals are ubiquitously distributed in the environment. Toxicological studies have indicated the associations between non-persistent pesticides and liver fibrosis in vitro and in vivo. However, epidemical study on the deleterious effect of non-persistent pesticides on the risk of liver fibrosis is rather limited.

The combination of auxin-mimicking herbicides from different chemical groups offers an alternative for controlling fleabane ( spp.) in soybean pre-sowing, but care is needed to avoid phytotoxicity. This study evaluated the effectiveness of auxinic herbicide mixtures in controlling spp.

These herbicides give rise to a number of key metabolites, with 3-methyl phosphinicopropionic acid (MPPA), -acetyl glufosinate (-acetyl GLUF), aminomethyl phosphonic acid (AMPA), -acetyl aminomethyl phosphonic acid (-acetyl AMPA), -acetyl glyphosate (-acetyl GLY), -methyl glyphosate (-methyl GLY) as the major metabolites obtained from GLUF and GLY. Extensive use of these herbicides may lead to their increased presence in the environment, especially aquatic ecosystems.

This study introduces an innovative electrochemical biosensor, engineered through the functionalization screen-printed electrode (SPE) with a coordination complex comprised of 4-mercaptobenzoic acid (4-MBA) and copper ions (Cu), achieving precise quantitative determination of glyphosate. Electrodepositing gold nanoparticles (AuNPs) onto the electrode surface, forming a self-assembled monolayer (SAM) of 4-MBA via thiol-gold interactions, and immobilizing Cu via coordination bonding with the monolayer, finalizing the electrochemical biosensor construction as Cu/4-MBA/AuNPs/SPE. The successful modification of the biosensor interface is confirmed through scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and electrochemical characterization.
