Spatiotemporally Synchronous Oxygen Self‐Supply and Reactive Oxygen Species Production on Z‐Scheme Heterostructures for Hypoxic Tumor Therapy

Advanced Materials, Journal Year: 2020, Volume and Issue: 32(11)

Published: Feb. 5, 2020

Abstract Photodynamic therapy (PDT) efficacy has been severely limited by oxygen (O 2 ) deficiency in tumors and the electron–hole separation inefficiency photosensitizers, especially long‐range diffusion of O toward photosensitizers during PDT process. Herein, novel bismuth sulfide (Bi S 3 )@bismuth (Bi) Z‐scheme heterostructured nanorods (NRs) are designed to realize spatiotemporally synchronous self‐supply production reactive species for hypoxic tumor therapy. Both narrow‐bandgap Bi components can be excited a near‐infrared laser generate abundant electrons holes. The heterostructure endows @Bi NRs with an efficient ability potent redox potentials, where hole on valence band react water supply electron conduction produce species. overcome major obstacles conventional process exhibit promising phototherapeutic effect, supplying new strategy elimination.

Recent advances in multifunctional nanomaterials for photothermal-enhanced Fenton-based chemodynamic tumor therapy

Materials Today Bio, Journal Year: 2022, Volume and Issue: 13, P. 100197 - 100197

Published: Jan. 1, 2022

Photothermal (PT)-enhanced Fenton-based chemodynamic therapy (CDT) has attracted a significant amount of research attention over the last five years as highly effective, safe, and tumor-specific nanomedicine-based therapy. CDT is new emerging nanocatalyst-based therapeutic strategy for in situ treatment tumors via Fenton reaction or Fenton-like reaction, which got fast progress recent because its high specificity activation by endogenous substances. A variety multifunctional nanomaterials such metal-, metal oxide-, metal-sulfide-based nanocatalysts have been designed constructed to trigger within tumor microenvironment (TME) generate cytotoxic hydroxyl radicals (•OH), efficient killing cells. However, still required enhance curative outcomes minimize side effects. Specifically, efficiency certain CDTs hindered TME, including low levels hydrogen peroxide (H2O2), overexpression reduced glutathione (GSH), catalytic efficacy reactions (pH 5.6-6.8), makes it difficult completely cure cancer using monotherapy. For this reason, photothermal (PTT) utilized combination with efficacy. More interestingly, heating during PTT not only causes damage cells but can also accelerate generation •OH reactions, thus enhancing efficacy, providing more effective when compared Currently, synergistic PT-enhanced both PT properties made enormous theranostics. there no comprehensive review on subject published date. In review, we first summarize treatment. We then discuss potential challenges future development nanocatalytic clinical application.
