Smart triblock dendritic unimolecular micelles as pioneering nanomaterials: Advancement pertaining to architecture and biomedical applications.

Recent interest in triblock dendritic unimolecular micelles has opened a new spectrum for its ubiquitous application in biomedical sciences specially drug delivery. Unimolecular dendritic micelles have brought significant attention due to their high encapsulation efficiency, high-functionality, and site specific confinement capabilities. During the last decade, the number of publications in this field has increased drastically, reinforced by the fact that several clinical trials are underway using micelles for drug delivery. This review unveils the most recent advancement on the synthesis and applications of cutting-edge unimolecular micelles using dendritic and star-shaped molecules emphasizing on triblock copolymers. The major biomedical applications covered in this manuscript are drug/gene/bio-macromolecules delivery to the site of interest, as contrast agents in bio-imaging, and cancer targeted theranostics using stimuli-responsive mechanism.
