Comparison of drug release from poly(lactide-co-glycolide) microspheres and novel fibre formulations.

Intraperitoneal cisplatin delivery has recently been shown to benefit ovarian cancer patients. Cisplatin-containing poly(lactide-co-glycolide) (PLGA) microspheres have been proposed for cisplatin delivery. The drug loading of cisplatin containing microspheres produced elsewhere is 3-10%w.

Objective assessment of nanoparticle disposition in mammalian skin after topical exposure.

The use of nanoparticles as formulation components of topical drug delivery systems for the skin has been widely investigated in the literature. Because of the conflicting conclusions resulting from these studies concerning the ultimate disposition of the nanoparticles employed, the research presented in this paper has been designed to evaluate objectively the fate of such structures when administered to mammalian skin. Confocal microscopy images of skin exposed to nanoparticles have therefore been assessed by quantitative statistical analysis.
