This is from November, 2020 and might very well be in use already.
“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.”
“The Johns Hopkins researchers fabricated the devices with about 6,000 theragrippers per 3-inch silicon wafer. In their animal experiments, they loaded a pain-relieving drug onto the grippers. The researchers’ studies found that the animals into which theragrippers were administered had higher concentrates of the pain reliever in their bloodstreams than did the control group. The drug stayed in the test subjects’ systems for nearly 12 hours versus two hours in the control group.”
According to Johns Hopkins University, Theragrippers are actually administered with a cotton swab.
In other words, any kind of swab test can easily be contaminated with these nano particles, delivering whatever they want into your body. For example, the same sh*t that are in the vaccines. Do not get tested!
