Abstract

We developed a new oil-based delivery system for transdermal protein delivery, a gel-in-oil (G/O) nanosuspension, where gelatin-based hydrogel was coated with hydrophobic surfactants. The high entrapment efficiency of a model protein, phycocyanin (PC), into nano-sized gelatin hydrogel particles was achieved. Spectroscopic evaluation of PC suggested that the G/O nanosuspension could retain the functional form of PC in isopropyl myristate. In vitro skin permeation studies showed that the G/O nanosuspension facilitated the delivery of PC through the stratum corneum of Yucatan micropig skin.
