Nano-Based Strategies Aiming at Tumor Microenvironment for Improved Cancer Therapy

Molecular Pharmaceutics, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Malignant tumors pose a considerable threat to human life and health. Traditional treatments, such as radiotherapy chemotherapy, often lack specificity, leading collateral damage normal tissues. Tumor microenvironment (TME) is characterized by hypoxia, acidity, redox imbalances, elevated ATP levels factors that collectively promote tumor growth metastasis. This review provides comprehensive overview of the nanoparticles developed in recent years for TME-responsive strategies or TME-modulating methods therapy. The focus on designing synthesizing can interact with achieve precisely controlled drug release. These activate release under specific conditions within environment, thereby enhancing efficacy drugs while reducing toxicity cells. Moreover, simply eliminating cells does not fundamentally solve problem. Only comprehensively regulating TME make it unsuitable cell survival proliferation we more thorough therapeutic effects reduce risk recurrence. regulation aim suppress metastasis modulating various components TME. only improve treatment outcomes but also have potential lay foundation future personalized cancer therapies.

Photocatalytic Degradation of Synozol Navy Blue Dye by Ni‐Cu‐Ag Dopped ZnO: An Insight Into Photoluminescence, Scavenging, Mechanism and Kinetic Aspects

Microscopy Research and Technique, Journal Year: 2025, Volume and Issue: unknown

Published: March 31, 2025

ABSTRACT Cost‐effective, sustainable, and eco‐friendly strategies are crucial for treating organic pollutants in industrial wastewater. ZnO is a promising photocatalyst due to its affordability, environmentally benign nature, ability fully mineralize pollutants. However, limited effectiveness under visible light major drawback. Ni doping helps reduce charge carrier recombination, enhancing the photocatalytic activity of ZnO. Ni‐Cu co‐doping increases saturation magnetization by creating intrinsic defects, though it can lead nanocluster formation on catalyst surface. Ag further improves performance preventing aggregation prolonging lifetimes. In this study, Ni‐Cu‐Ag@ZnO nanoparticles were synthesized via sol–gel method used as degradation Synozol navy blue dye. Characterization techniques like FTIR, SEM, XRD, EDX, BET, UV, PL confirmed nanocomposite structure morphology. The achieved 88% photodegradation efficiency optimal conditions (a contact time 50 min, an initial dye concentration 75 ppm, dosage 0.03 g, acidic medium with pH 2). rate constants, k 1 (2 × 10 −2 min −1 ) suggest that ordinary follows pseudo‐first‐order kinetics. Scavenging tests enhanced was driven generation OH • radicals, addition hydrogen peroxide playing key role electron–hole recombination. This indicates quantity hydroxyl radicals their adsorption determining extent degradation. study highlights potential nanocomposites wastewater treatment opens new avenues enhancement other catalysts consideration.
