Concern is growing that an innovative nanotech device developed at Johns Hopkins University may be used to secretly deliver the COVID19 vaccine to those people who are “vaccine hesitant.”
Certainly, the technology is real, but is there any merit to such a claim?
Patrick Smith (November 25, 2020) writing for hub.jhu.edu explains:
Inspired by a parasitic worm that digs its sharp teeth into its host’s intestines, Johns Hopkins researchers have designed tiny, star-shaped microdevices that can latch onto intestinal mucosa and release drugs into the body.
David Gracias, a professor in the Whiting School of Engineering, and gastroenterologist Florin M. Selaru, director of the Johns Hopkins Inflammatory Bowel Disease Center, led a team of researchers and biomedical engineers that designed and tested shape-changing microdevices that mimic the way the parasitic hookworm affixes itself to an organism’s intestines.
Called “theragrippers” these tiny devices are made of metal and a thin, shape-changing film. They are coated in heat-sensitive paraffin wax and each is no bigger than a speck of dust (see image below).
