Transdermal insulin delivery is a promising method for diabetes management, providing the potential for controlled, sustained release and prolonged insulin effectiveness. However, the large molecular weight of insulin hinders its passive absorption through the stratum corneum (SC) of the skin, and high doses of insulin are required, which limits the commercial viability. We developed ethosome (ET) and -ethosome (TET) nanovesicle formulations containing a biocompatible lipid-based ionic liquid, [EDMPC][Lin], dissolved in 35% ethanol.

This experimental study reports the thermodynamic influence of three different amino acids on methane hydrate in oil-dominated systems, namely, glycine, proline, and alanine. To thoroughly examine the effect of selected amino acids on methane (CH) hydrate formation compared to the commercial inhibitor monoethylene glycol (MEG) in the presence of oil, the hydrate liquid-vapor equilibrium (H-Lw-Lo-V) curve is used to measure amino acid aqueous solutions. All experiments are performed at a concentration of 10 wt % by using the isochoric T-cycle technique in a high-pressure reactor cell at the selected range of pressures with temperatures of 4.
