NEWARK, Del., Nov. 11 (UPI) -- U.S. scientists say they developed a squishy gel that when compressed -- like at a painful knee joint -- releases anti-inflammatory medicine.
Xinqiao Jia, Chandran R. Sabanayagam and colleagues at the University of Delaware said in the past few decades, researchers have been developing a variety of "smart" hydrogels that can release medications over several days rather than in a single burst.
