Phase and Defect Engineering of MoSe₂ Nanosheets for Enhanced NIR-II Photothermal Immunotherapy

Nano Letters, Journal Year: 2024, Volume and Issue: 24(25), P. 7764 - 7773

Published: June 12, 2024

Inducing immunogenic cell death (ICD) during photothermal therapy (PTT) has the potential to effectively trigger immunotherapy (PTI). However, ICD induced by PTT alone is often limited inefficient PTT, low immunogenicity of tumor cells, and a dysregulated redox microenvironment. Herein, we develop MoSe2 nanosheets with high-percentage metallic 1T phase rich exposed active Mo centers through defect engineering as an effective nanoagent for PTI. The in endows them strong performance, abundant endow high activity glutathione (GSH) depletion. MoSe2-mediated high-performance synergizing efficient GSH depletion facilitates release tumor-associated antigens induce robust ICD, thus significantly enhancing checkpoint blockade activating systemic immune response mouse models colorectal cancer triple-negative metastatic breast cancer.

In atomically thin two-dimensional (2D) materials, grain boundaries (GBs) are ubiquitous, displaying a profound effect on the electronic structure of host lattice. The random configuration atoms within GBs introduces an arbitrary and unpredictable local environment, which may hazard electron transport. Herein, by utilizing Pt single-atom chains with ultimate one-dimensional (1D) feature (width single atom length up to tens nanometers), we realized suture pathway at diversified transition metal dichalcogenides (TMDCs). Theoretical calculations reveal that construction sutures (SAS) prompts emergence states proximal Fermi level, effectively modulating transformation from semiconductivity metallicity. This underscores pivotal role SAS in reconfiguring pathway. Benefiting this, SAS-MoS2 emerges as excellent catalyst, exhibiting overpotential 41 mV 10 mA cm-2 Tafel slope 54 dec-1 hydrogen evolution reaction.
