<p>Nanotechnology has resolved the inherent limitations of traditional therapy. The use of multifunctional micelles nanoparticles (MMNs) to deliver drug products is a groundbreaking delivery process as it has replaced what was the limitation of delivery. Furthermore, researchers have been able to formulate an innovative, flexible drug delivery system that is able to navigate many of the limitations of traditional drug delivery techniques. The benefits of drug solubility, protection from drug degradation, and the ability to deliver to specific cells, or specific tissues by surface modification can reduce systemic toxicity of toxicants and improve therapeutic effects. This review summarizes the latest developments in MMNs for the treatment of several conditions like cancer, cardiovascular disease, neurological disorders, and how they are allowing patients who were non-responsive due to resistance, regain responsiveness and improve existing drug congeners. A critical discussion of the potential challenges of MMN clinical delivery, scalable production of MMNs, regulatory approval, and overall potential adverse effects has been discussed.</p> Graphical Abstract <p></p>
