Abstract
The rapid development of nanotechnology has resulted in the widespread use of nanoparticles (NPs) in various sectors due to their unique properties and diverse applications. However, the increased exposure of humans to NPs raises concerns about their potential negative impact on human health and the environment. The pathways through which NPs exert adverse effects, including inflammation and oxidative stress, are primarily influenced by their size, shape, surface charge, and chemistry, underscoring the critical need to comprehend and alleviate their potential detrimental impacts. In this context, the natural flavonoid quercetin is a promising candidate for counteracting the toxicity induced by NPs due to its anti-inflammatory and antioxidant properties. This review provides an overview of the existing literature on quercetin's protective effects against NPs-induced toxicity, highlighting its therapeutic benefits and mechanisms of action, focusing on its ability to alleviate oxidative stress, inflammation, and cellular damage caused by various types of NPs. Insights from both in vitro and in vivo studies demonstrate the effectiveness of quercetin in preserving cellular function, modulating apoptotic pathways, and maintaining tissue integrity in the presence of NPs. The potential of quercetin as a natural therapeutic agent against NPs-induced toxicity provides valuable insights for safer use of NPs in various daily applications.
