NIR-absorbing dye functionalized hollow mesoporous silica nanoparticles for combined photothermal–chemotherapy

Multifunctional hollow mesoporous silica nanoparticles were constructed by firstly loading with doxorubicin and then capping with disulfide linked β-cyclodextrin followed by complexation with adamantane functionalized indocyanine dye, showing improved anticancer efficacy through combined photothermal–chemotherapy.
