A comparative study on micelles, liposomes and solid lipid nanoparticles for paclitaxel delivery.

The purpose of this work was to compare the in vitro and in vivo characteristics of LDV-targeted lipid-based micelles, liposomes and solid lipid nanoparticles (SLN) to provide further insights into their therapeutic potential for clinical development. Micelles, liposomes and SLN were prepared using LDV peptide amphiphiles and palmitic acid-derived lipids using solvent evaporation, thin-film hydration and microfluidic mixing respectively. Nanocarriers were characterized for their physicochemical properties, paclitaxel loading efficiency, in vitro release behavior, stability in biological media as well as in vivo antitumor efficacy in melanoma xenograft model.

Effect of ceramic filler content on the mechanical and thermal behaviour of poly-L-lactic acid and poly-L-lactic-co-glycolic acid composites for medical applications.

One main application of resorbable poly-L-lactic acid (PLLA) and poly-L-lactic-co-glycolic acid (PLGA) based materials is in medical implants. In this study composites were made from PLLA and PLGA with hydroxyapatite (HAp) respective beta-tricalcium phosphate (beta-TCP) fillers. The filler content and particle size were varied, and the thermal properties as well as the mechanical strength of the composites were investigated.
