Research progress on self-assembled nanodrug delivery systems

Abstract

In recent years, nanodrug delivery systems have attracted increasing attention due to their advantages, such as high drug loading, low toxicity and side effects, improved bioavailability, long circulation time, good targeting and controlled drug release efficiency. Self-assembly technology has developed rapidly in recent decades and plays an important role in the research and development of nanoscience. The combination of nanometer drug delivery and self-assembly technology can realize the self-delivery process of drugs. The facile synthesis process and strong biological affinity can both effectively enhance the therapeutic efficacy and reduce the toxicity of drugs. This combination of technologies has received wide attention in the field of nanobiomedicine. In this review, we summarize the research progress and applications of different types of self-assembled nanodrug delivery systems (amphiphilic block copolymer-based self-assembled drug delivery system, carrier-free nanodrugs, peptide-based self-assembled delivery system, metal-polyphenol self-assembly and natural small-molecule self-assembled nanodrug delivery systems), which are expected to have potential therapeutic value in the field of biomedicine in the future.
