The manganese doped zinc sulfide nanoparticles were synthesized by simple aqueous chemical reaction of manganese chloride, zinc acetate and thioacitamide in aqueous solution. Thioglycolic acid is used as capping agent for controlling the nanoparticle size. The main advantage of the ZnS:Mn nanoparticles of diameter ~2.73nm is that the sample is prepared by using non-toxic precursors in a cost effective and eco-friendly way. The structural, morphological and chemical composition of the nanoparticles have been investigated by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) with energy dispersion spectroscopy (EDS) and Fourier transform infrared (FTIR) spectroscopy. The nanosize of the prepared nanoparticles was elucidated by Scanning Electron Microscopy (SEM). FTIR result ensures that Thioglycolic acid is well bonded on the surface of ZnS:Mn NPs. The antifungal effects of Thioglycolic acid capped ZnS:Mn nanoparticles exhibited a potent antifungal activity against tested fungal strains, so deserving further investigation for clinical applications. The antifungal property of manganese doped zinc sulphide nanoparticles is attributed to the generation of reactive oxygen species due to the interaction of nanoparticles with water. Additionally, the presence of Zn and S in the zone of inhibition area leads to perturbation of fungi cell membranes resulting in growth inhibition.

Metal polyphenolic networks (MPNs) are becoming more and more attractive for nontoxic hair dyeing, but their coloring effect is not satisfactory because of the limited interfacial deposition and the absence of internal deposition. Moreover, there is a lack of understanding of the driving factors of the interfacial deposition of MPNs on hair. Herein, we develop a simple yet efficient strategy that transforms disulfide bonds of the hair into thiol groups by thioglycolic acid (TGA) to highly enhance the coloring effect of MPNs at a low temperature.

Detrimental effects of terminal heat stress could be mitigated by exogenous application of synthetic compounds by preserving cell membrane integrity and protecting against oxidative damage. A field experiment was conducted to test the application of seven synthetic compounds on wheat growth traits: (1) thiourea (20 mM and 40mM); (2) potassium nitrate (1% and 2%); (3) sodium nitroprusside (400 μg mL-1 and 800μg mL-1 ); (4) dithiothreitol (25 ppm and 50ppm); (5) salicylic acid (100 ppm and 200ppm); (6) thioglycolic acid (200 ppm and 500ppm); and (7) putrescine (4 mM and 6mM). These compounds were applied at the anthesis and grain-filling stages to enhance physio-biochemical traits and yield attributes of wheat (Triticum aestivum ) cvs GW-11 and GW-496 under terminal heat stress.

The immune system is essential for the defense against infections and is critically implicated in various disorders, including immunodeficiency, autoimmunity, inflammation and cancer. The current study includes a new design of palmitoylated derivatives of thioglycolic acids (PTGAs) capable of triggering innate immune responses. The new series were accessible through a three-step synthetic route, including N-palmitoylation, Claisen-Schmidt condensation and thia-Michael addition.

Due to its simple process and adaptability to large-area deposition, chemical bath deposition (CBD) is one of the preparation methods for the SnO layer in highly efficient "n-i-p" structured perovskite solar cells (PSCs). However, the residual thioglycolic acid (TGA) on the CBD-SnO surface affects the stability of PSCs and the carrier transport at the CBD-SnO/perovskite interface, hindering the further development of this method. This work demonstrates a method for the reutilization of surface groups to construct molecular bridges.
