Synthesis of disulfide-based biodegradable bridged silsesquioxane nanoparticles for two-photon imaging and therapy of cancer cells

Chem Commun (Camb). 2015 Aug 7;51(61):12324-7. doi: 10.1039/c5cc03736k.

Abstract

Biodegradable bridged silsesquioxane (BS) nanomaterials for two-photon-excited (TPE) imaging and therapy of breast cancer cells were described. A versatile synthesis was developed to design monodisperse tetra-alkoxysilylated diamino-diphenylbutadiene or Zn-porphyrin-based nanospheres of 30 to 50 nm.
