Artificial DNA Controls Sequenced Release of Drugs from a Capsule
August 13, 2019 | Terry Sharrer
The earliest controlled release drug dates from 1938, and relied on polymer coatings to survive gastric acids until the coating dissolved slowly in the intestines. In this piece, German scientists demonstrate how it is possible to encapsulate three different drugs in silver, iron oxide, and gold nanoparticles, which a hydrogel containing artificial DNA holds together until each drug is released in sequence over time.
