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