Carbon nanomaterials have flourished for cancer therapy for decades. However, their practical applications on clinical bases still pose a challenge to address the dilemma of metabolism in vivo. In this study, an attempt is made to design a degradable carbon-silica nanocomposite (CSN) with immunoadjuvant property, which could undergo an enzyme-free degradation process into small particles (∼5 nm) and facilitate its clinical application. CSN harbors photothermal and photodynamic properties and as an immunoadjuvant would help to generate tumor-associated antigens and mature dendritic cells (DCs). Potent antitumor effects have been achieved in both 4T1 and patient-derived xenograft tumor models with tumor inhibition efficiencies of 93.2% and 92.5%, respectively. We believe that this strategy will benefit the possible clinical translation and carbon-silica-nanomaterial-based cancer therapy.
