This work designs a class of biocompatible PEG‐chitosan@CDs hybrid nanogels by integrating nonlinear poly(ethylene glycol) (PEG), chitosan, and graphitic carbon dots (CDs) into a single nanoparticle for two‐photon fluorescence (TPF) bioimaging, pH and near‐infrared (NIR) light dual‐responsive drug release, and synergistic therapy. Such hybrid nanogels can be simply prepared from a one‐pot surfactant‐free...
An efficient nanomedical platform that can combine two-photon cell imaging, near infrared (NIR) light and pH dual responsive drug delivery, and photothermal treatment was successfully developed based on fluorescent porous carbon-nanocapsules (FPC-NCs, size ∼100 nm) with carbon dots (CDs) embedded in the shell. The stable, excitation wavelength (λ ex )-tunable and upconverted fluorescence from...
