Novel nanogels hold promise for improved drug delivery to cancer patients

Researchers at The University of Texas at Austin have developed new guidelines for fabricating nanoscale gel materials, or nanogels, that can deliver numerous therapeutic treatments to treat cancer in a precise manner. In addition to enabling the delivery of drugs in response to tumors, their nanogels can target malignant cells (or biomarkers), degrade into nontoxic components and execute multiple
