Abstract
AbstractBiocompatible nanoparticles have attracted considerable attention as cellular antioxidant agents for the improvement of new therapeutics for several and diverse oxidative stress related disorders. Here, it is shown that the biocompatible cell membrane@gold nanoparticle displays catalase‐mimic behavior by decomposing H2O2. This interesting behavior can be used for cell protection against induced oxidative injury by reactive oxygen species (ROS). So, after characterizing this novel biocompatible nanostructure, the protective effect of cell membrane@AuNPs pretreatment in front of a well‐defined oxidative stress‐inducing chemotherapy drug, doxorubicin (Dox) is assessed. Doxorubicin pretreatment significantly reduces the intracellular ROS production. Similarly, a reduction in the levels of DNA oxidative damage, as measured with the AO/EB staining, is also observed. Obtained results would support that this novel nanostructure can show how a pharmacological agent can be used against oxidative stress‐mediated diseases.
