A tellurylsulfide bond-containing redox-responsive superparamagnetic nanogel with acid-responsiveness for efficient anticancer therapy

A tellurylsulfide bond-containing biopolymer nanogel was first fabricated to achieve smart drug release. The reductive nanogel exhibited highly sensitive reduction-responsiveness, fast internalization, and efficient anticancer therapy. This approach displays a new potential of tellurylsulfide bond-containing nanocarriers for drug delivery.
