Researchers develop drug delivery method using proline, found in chicken feathers, to potentially limit chemotherapy side effects, targeting tumors more directly.

Researchers have developed a drug delivery method using proline, an amino acid found in chicken feathers, to potentially limit chemotherapy side effects and repair enzymes. The new approach involves designing a cage made of biologically compatible peptides, which can transport drugs with high precision. This method may help target chemotherapy drugs more directly at tumors, reducing harm to healthy cells.
