The Eco-Friendly Preparation of Se, Zn, and Ag MONPs and Their Current Medical Applications and Drug Delivery for AD Diseases.

In recent decades, significant progress has been made in the field of nanotechnology that enabled researchers to promote and create nanoshaped compounds with attractive physicochemical properties. These materials were used in different biomedical applications, because of the superior quality of nanoparticles and nano-oxide materials compared with their bulky counterparts in the fields of medicine and healthcare. This gives a push to this line of science toward making a great progress. Despite the positive benefits associated with nanofield usages, nanomaterials have cytotoxic effects which are directly associated with their physiochemical properties. Therefore, proper control of factors governing nanoparticle synthesis can improve biocompatibility and minimize toxicity, which would enable researchers to achieve more suitable outcomes. In our review, we focus on the significant progress in the field of MONPs, covering their synthesis and applications, as well as the methods of preparations and their chemical or physical qualities. In addition to their antibacterial effectiveness, MONPs also exhibit biological effects, like antitumor, anticancer, proregenerative, and drug delivery properties. The last part of this review highlights the use of oxide nanoparticles for drug delivery in brain illness therapy and their potential in the treatment of brain diseases.
