An engineered cascade-sensitized red-emitting upconversion nanoplatform with a tandem hydrophobic hydration-shell and metal-phenolic network decoration for single 808 nm triggered simultaneous tumor PDT and PTT enhanced CDT

Efficient Nd 3+ → Yb 3+ → Tm 3+ → Er 3+ cascade-sensitized red-emitting UCNP, with tandem hydrophobic hydration-shell and metal-phenolic network decorations, was designed to achieve single 808 nm triggered simultaneous tumor PDT and PTT enhanced CDT.
