Data from University of Bath Advance Knowledge in Drug Delivery Systems

February 19, 2014

By a News Reporter-Staff News Editor at Biotech Week -- New research on Drugs and Therapies is the subject of a report. According to news reporting originating from Bath, United Kingdom, by NewsRx correspondents, research stated, "Stimulated Raman scattering microscopy was used to assess the permeation of topically applied drugs and formulation excipients into porcine skin. This chemically selective technique generates high-resolution 3D images, from which semi-quantitative information may be elucidated."

Our news editors obtained a quote from the research from the University of Bath, "Ibuprofen, applied as a close-to-saturated solution in propylene glycol, was directly observed to crystallise in/on the skin, as the co-solvent permeated more rapidly, resulting in precipitation of the drug. Coherent Raman scattering microscopy is also an excellent tool, in conjunction with more conventional confocal fluorescence microscopy, with which to image micro/nanoparticle-based formulations."

According to the news editors, the research concluded: "Specifically, the uptake of particles into thermal ablation transport pathways in the skin has been examined."
