1D Coordination Polymer Nanofibers for Low‐Temperature Photothermal Therapy

Near-infrared (NIR)-light-triggered photothermal therapy (PTT) usually requires hyperthermia to >50 °C for effective tumor ablation, which can potentially induce inflammatory disease and heating damage of normal organs nearby, while tumor lesions without sufficient heating (e.g., the internal part) may survive after treatment. Achieving effective tumor killing under relatively low temperatures is thus critical toward successful clinical use of PTT. Herein, we design a simple strategy to fabricate poly(ethylene glycol) (PEG)-modified one-dimensional nanoscale coordination polymers (1D-NCPs) with intrinsic biodegradability, large surface area, pH-responsive behaviors, and versatile theranostic functions.
