Nanotechnology is important for the development of new materials capable to improve the development of novel drug delivery systems. Such systems may result in more efficient therapeutic effects with reduced toxicity and extended time in the organism and increase in bioavailability, biocompatibility, and solubility of drugs. Here it was investigated the interaction between the triblock copolymer Pluronic F127 (F127) and a natural bioactive amphiphilic saponin (SAP), extracted from Glycyrrhiza gla...

: Carbendazim (MBC) is a fungicide widely used in agriculture which allows the high productivity of several cultures, a necessary condition considering the growing of the world population. Moreover, MBC has environmental impact mainly on the soil and water sources, and consequently, on animal and human lives. However, even though the toxicity of fungicides is well established, their action mechanism in cell membranes are not completely understood. Herein, we investigate the interaction of differ...

Abstract Global environmental concerns on the production, usage and disposal of multiple human-made products have encouraged the study and development of new more ecological materials based on or inspired by biomolecules that may ultimately replace the current existing options. These efforts include the development of sugar-based surfactants. They have been increasingly adopted in selected applications to replace conventional surfactants. Sorbitan ester is a good example of a sugar-based surfact...

Triblock copolymers, such as Pluronic F127 (F127), are pharmaceutically important amphiphilic compounds that self-assemble in aqueous solution either as discrete or entangled micelles, depending on their concentration and temperature, which may function as drug delivery vehicle. Herein, we have synthesized the antimicrobial peptide tritrpticin (TRP3), a tryptophan (Trp)- and arginine (Arg)-rich peptide, sequence VRRFPWWWPFLRR, with a broad spectrum of action against bacteria and fungi, to invest...

Abstract The interaction between polymer and lipid vesicles may result in stabilization and formation of highly ordered networks, which can mimic biological membranes and be used as drug delivery system. Here we used differential scanning calorimetry (DSC) and Langmuir–Blodgett (LB) techniques to describe the effect of the nonionic water-soluble poly(ethylene glycol), PEG 35 kDa, on vesicles or monolayers from the cationic dialkyldimethylammonium bromide, D n DAB ( n = 12–18). Based on DSC data,...
