A Self-Therapeutic Upconversion Polyphenolic Nanoreactor for NIR-Assisted Multifaceted ROS Generation and Dual Chemotherapy

Conventional chemotherapy with drug-loaded hybrid nanosystems is restricted by limited drug delivery, poor loading content, internal accumulation, or premature drug release. Drug-derived nanoreactors acting as self-therapeutic agents are considered a promising approach to address these challenges. Herein, we report a...

Orthogonal upconversion mimicking Nd-Mn heterometallic nanocomposite for dual NIR responsive self-amplifying photodynamic/chemodynamic therapy.

Shallow tissue penetration of excitation light remains the most persistent barrier to effective photodynamic therapy (PDT), compounded further by tumour hypoxia and elevated glutathione (GSH). Herein, we report a rationally engineered core-shell nanoplatform comprising a Mn-centred porphyrinic metal-organic framework c...
