One-step photo synthesis of protein-drug nanoassemblies for drug delivery.

Upon controlled UV illumination, disulfide bonds in bovine α-lactalbumin (BLA) are selectively broken, leading to self-assembly of the BLA and doxorubicin (DOX) molecules into nanoparticles via hydrophobic interactions and intermolecular disulfide bonds. Such protein-drug nanoparticles have synergistic anticancer activity in vitro and tumor-homing specificity in vivo, which are of great potential for systemic drug delivery in cancer therapy.
