For the first time, researchers have shown that a nonbiological molecule called a plastic antibody can work just like a natural antibody. In animal tests, the plastic particles bind to and neutralize a toxin found in bee stings; the toxin and antibody are then cleared to the liver, the same path taken by natural antibodies. Researchers are now developing plastic antibodies for a wider range of disease targets in hopes of broadening the availability of antibody therapies, which are currently very expensive.
