research pH-Responsive Nanogels from Bioinspired Comb-like Polymers with Hydrophobic Grafts for Effective Oral Delivery
This study demonstrates that pH-responsive nanogels designed with comb-like anionic polymers significantly improved oral delivery of the chemotherapy drug camptothecin, enhancing drug stability in acidic conditions and release in the intestines, with increased cellular uptake and cytotoxic effects against colorectal carcinoma cells.
