Delivering Actives via Solid Lipid Nanoparticles and Nanostructured Lipid Carriers: Part I

By: Johann W. Wiechers, PhD, JW Solutions, and Eli…

This first of a two-part series on SLNs and NLCs describes the differences between the two types and their delivery capabilities. The terms solid lipid nanoparticles and nanostructured lipid carriers are not very useful to distinguish these two delivery systems since both are solid, both are lipids, both are nanoparticles, and both are carrier systems. The only real difference between the two is the purity of the single lipid used in SLNs or multiple lipids used, i.e. one solid and one liquid, in NLCs. This factor has an enormous impact on the crystallinity of the lipid phase, which subsequently influences the loading capacity of the system for encapsulated active ingredients or API.

Au Naturale Nanoparticle Sun Protection

By: Katie Schaefer, C&T magazine

In 1876, Charles Darwin observed the secretion of yellow matter from the rootlets of ivy. Little was known about the material until 2008, when Mingjun Zhang, PhD, an associate professor of biomedical engineering at the University of Tennessee, and his research team found nanoparticles in the yellow matter.

Skin Toxicology—The Future May Be Orange

By: Johann Wiechers, PhD, JW Solutions

Here, industry expert Johann Wiechers, PhD, discusses the frequent use of percentages by toxicologists to calculate skin penetration. To relate this discussion to modern day events, Wiechers describes the skin penetration of orange paint, used by fans of the Dutch national football team.
