Smart DNA nanogel coated polydopamine nanoparticle with high drug loading for chemo-photothermal therapy of cancer

A smart deoxyribose nucleic acid nanogel coated polydopamine nanosphere hybrid was designed for chemo-photothermal therapy of cancer. The nanohybrid showed good colloid stability, narrow size distribution, high drug loading, good biocompatibility, and high photothermal conversion efficiency, and could release the drug on desired tumor sites.
