Nanoscale bottles protect fatty acid payloads

By Lisa McDonald / August 23, 2019

Fatty acids, although biodegradable and biocompatible, experience poor dispersibility and stability under physiological conditions, hindering their application as drug-carrying materials. Researchers at Georgia Tech and Shandong University created silica-based nanocapsules that safely carry drug-containing fatty acids to a targeted destination.
