New micromaterial releases nanoparticles that selectively destroy cancer cells

Researchers have developed micromaterials made up only of proteins, capable of delivering over an extended period of time nanoparticles that attack specific cancer cells and destroy them. The micromaterials mimic natural secretory granules found in the endocrine system and were proven effective in mouse models of colorectal cancer.

The new micromaterials developed by researchers are formed by chains of amino acids known as polypeptides, which are functional and bioavailable in the form of nanoparticles that can be released and targeted to specific types of cancer cells, for selective destruction.
