This review article describes the synthesis, properties and some applications of star-shaped polymers. The arms constituted of homo- or co-polymers of different polymers are also reviewed. Methods of synthesis of various types of star-shaped polymers, including “arm first” and “core first” procedures,  is given as an introduction along with some details. Then, the synthesis of star polymers (including miktoarm stars) with strictly defined as well as with varying number of arms and having cores formed from small and/or large molecules: branched, cross-linked, etc., is described. Interest in star-shaped and branched systems based on poly (ethylene oxide) (PEO) is mainly motivated by their potential applications in the biomedical and pharmaceutical areas. The properties and applications of PEO stars are also reported, such as drug carriers, surface modifiers, hydrogels, components of membranes, and also have some biomedical applications. Their potential applications as components of different types of complexes, hydrogels, networks, and ultrathin coatings are indicated.

Background: Molecularly Imprinted Polymers (MIPs), a type of biomimetic materials have attracted considerable interest owing to their cost-effectiveness, good physiochemical stability, favorable specificity and selectivity for target analytes, and long shelf life. These materials are able to mimic natural recognition entities, including biological receptors and antibodies, providing a versatile platform to achieve the desirable functionality for various biomedical applications. Objective: In this review article, we introduce the most recent development of MIPs to date. We first highlight the advantages of using MIPs for a broad range of biomedical applications. We then review their various methods of synthesis along with their latest progress in biomedical applications, including biosensing, drug delivery, cell imaging and drug discovery. Lastly, the existing challenges and future perspectives of MIPs for biomedical applications are briefly discussed. Conclusion: We envision that MIPs may be used as potential materials for diverse biomedical applications in the near future.
