Advancements in research on the precise eradication of cancer cells through nanophotocatalytic technology

Frontiers in Oncology, Journal Year: 2025, Volume and Issue: 15

Published: April 1, 2025

The rapid development of nanotechnology has significantly advanced the application nanophotocatalysis in medical field, particularly for cancer therapy. Traditional treatments, such as chemotherapy and radiotherapy, often cause severe side effects, including damage to healthy tissues drug resistance. In contrast, nanophotocatalytic therapy offers a promising approach by utilizing nanomaterials that generate reactive oxygen species (ROS) under light activation, allowing precise tumor targeting minimizing collateral surrounding tissues. This review systematically explores latest advancements highly efficient nanophotocatalysts treatment, focusing on their toxicological profiles, underlying mechanisms cell eradication, potential clinical application. Recent research shows nanophotocatalysts, TiO2, In2O3, g-C3N4 composites, along with photocatalysts high conduction band or valence positions, ROS irradiation, which induces oxidative stress leads apoptosis necrosis. These cellular interacting key biological molecules DNA, proteins, lipids, triggering cascade biochemical reactions ultimately result death. Furthermore, strategies S-scheme heterojunctions vacancies (OVs) have been incorporated enhance charge separation efficiency absorption, resulting increased generation, improves photocatalytic performance targeting. Notably, these exhibit low toxicity cells, making them safe effective treatment modality. also discusses challenges associated therapy, limitations penetration need improved biocompatibility. findings suggest technology holds significant precision paving way safer more strategies.
