Novel biomaterial delivers medication directly to fish gut

A novel biomaterial developed at the Federal University of São Paulo (UNIFESP) in Brazil can help solve two problems at once. As a bioparticle, it can act as a drug carrier, delivering medication directly to the gastrointestinal tract of fish in order to circumvent resistance to conventional antibiotics, for example. In addition, it is administered orally in powder form and is highly palatable to fish, increasing the probability of effective treatment while at the same time reducing the waste and pollution inherent in the medication of these animals.
