Biodegradable, bile salt microparticles for localized fat dissolution.

ABSTRACT: Bile acids are proposed as therapeutic agents for various diseases, including liver diseases and obesity. However, oral or subcutaneous administration of a solubilized version of these drugs has limited efficacy and imposes unwanted side effects. Here, we describe a gold-templating method for fabricating stable, bile salt-cholate or deoxycholate-microparticles. The gold ions' reduction at the oil-water interface in a double emulsion solvent evaporation process enables a gold-bile salt interaction and the formation of bile salt particles. We demonstrate that composite microparticles release cholate/deoxycholate into solution via a surface erosion process. We illustrate these particles' capability to lyse adipocytes, both in vitro and in vivo, with minimal side effects, contrary to the Food
