Self-assembly of differently charged trimesic based lithocholic amphiphiles and their assessment on antimicrobial and biostimulant properties.

Biosurfactant based biostimulants plays a vital role in agriculture filed by enhancing the soil quality, promote plant growth, and eliminate plant pathogens, and increasing nutrient uptake. This manuscript describes the synthesis of trimesic based lithocholic ester functionalized amphiphiles (TMLCEA) with oppositely charged head groups using thiol-yne click chemistry, which is an effective and simple approach. The trimesic based lithocholic ester functionalized zwitterionic penicillamine (TMLCEPA), cationic cysteamine·HCl (TMLCECy), and anionic thiomalic acid (TMLCETM) exhibited hierarchically self-assembled microstructures from below to above the CMC.

Eco-friendly synthesis of N- cholyl mercapto histidine capped silver nanoparticles and its sensing of mercury (II) ions and photo catalytic degradation of methyl orange.

In this report, we have developed highly water soluble and stable silver nanoparticles (Ag NPs) utilizing N-Cholyl Mercapto Histidine (NCMH) as a reducing and stabilizing agent with near the primary critical micellar concentration (CMC) under ambient sunlight irradiation. Moreover, The NCMH was firstly synthesized by demonstrating the reaction between cholic acid and 2- Mercapto Histidine through a simple acid amine coupling approach. The primary and secondary CMC of NCMH surfactant was measured by pyrene (1 × 10 M) as a fluorescent probe, and values were found to be 3.

Direct sunlight induced room temperature synthesis of anticancer and catalytic silver nanoparticles by shrimp shell waste derived chitosan.

The use of marine waste derived chitosan (CS) for the synthesis of nanomaterials is considered as one of the effective routes for bio-waste management and recovering functional products. Herein, CS capped silver nanoparticles (Ag NPs-CS) with potential anticancer and dye pollutants adoption properties have been synthesized photochemically under direct sunlight. To obtain, CS, shrimp shell waste was subjected to a serious of standard demineralization, deproteinization and deacetylation processes.
