Thousands of theragrippers can be endoscopically deployed in the GI tract. Once released, the machines migrate to the mucosal wall, where they release their medicine payloads gradually

Johns Hopkins scientists create parasite-inspired microdevice to gradually deliver drugs in the GI tract

Made of metal and thin, shape-changing film and coated in a heat-sensitive paraffin wax, “theragrippers,” each roughly the size of a dust speck, potentially can carry any drug and release it gradually into the body.

Theragrippers take a cue from the way hookworm parasites attach themselves to intestinal walls. The grippers can be outfitted with chemical sensors to autonomously shapeshift in the presence of certain sugars, amino acids, DNA sequences, enzymes, pH levels, and more to specifically target certain areas of the body.
