A paper titled “Characterization of physicochemical properties of ivy nanoparticles for cosmetic application” in the February 2013 issue of the Journal of Nanobiotechnology used our 300 kDa Biotech CE Dialysis Tubing to purify nanoparticles naturally occurring in English ivy. After filtering the nanoparticles, the ivy filtrate was dialyzed to purify and homogenize the particle size.

The scientists at the University of Tennessee sought the physiochemical properties of ivy nanoparticles as an alternative to the metal oxides currently used in sunscreens. They determined that the ivy nanoparticles has advantages over the traditional metal oxides.

Background: Naturally occurring nanoparticles isolated from English ivy (Hedera helix) have previously been proposed as an alternative to metallic nanoparticles as sunscreen fillers due to their effective UV extinction property, low toxicity and potential biodegradability.

The scientists continue their research into ivy nanoparticles, and “future studies will focus on isolation and identification proteins from ivy nanoparticles”. In 2016 the same team of researchers published an article highlighting ivy nanoparticles in adhesive applications.
