“…Recently, some novel trends in this field have emerged, with the most popular being the fabrication of complex systems with stimuli‐responsive POSS‐hybrid polymers and biomolecules, including peptide, DNA, biotin, and other photosensitizers. Owing to the flexibility of incorporation with biomolecules and desirable self‐assembly behavior, POSS‐hybrid polymers have been produced for some novel biomedical applications, including gene vectors, target drug release systems, and PDT agents . All POSS‐hybrid polymers involved in this section are listed in Table 3 by order of appearance.…”

Polyhedral oligomeric silsesquioxane (POSS)‐hybrid polymers have been successfully employed as functional inorganic–organic hybrid materials for various applications due to their well‐determined structures. The past 6 years has witnessed growing interest in the rational design and synthetic approaches for POSS‐hybrid polymers, driven by the adoption of controlled living radial polymerization and click chemistry. This review addresses developments in the precise manipulation of POSS building blocks via atom transfer radical polymerization, reversible addition–fragmentation chain transfer, and click chemistry. Not only are the structures of POSS‐hybrid polymers tunable in terms of chemical composition, molecular weight, and polydispersity, but they are also controllable in sequential and hierarchical chain topology. Finally, some representative cutting‐edge applications of POSS‐hybrid polymers, including biomedical and energy‐related materials, fabrication of nanostructures, and functional surface coating materials, are highlighted.

“…The biocompatibility and nontoxicity of POSSs has attracted extensive research on their potential applications such as cytocompatibility [ 58 , 59 ], construction of capillary beds [ 60 ], and antithrombogenicity [ 61 , 62 ], etc. Ata and coworkers incorporated methacryloisobutyl POSS (MAPOSS) into hydrogel to improve hemocompatibility and lower platelet adhesion on the hydrogel surface.…”

“…Ata and coworkers incorporated methacryloisobutyl POSS (MAPOSS) into hydrogel to improve hemocompatibility and lower platelet adhesion on the hydrogel surface. Results indicated that the presence of POSS could help to reduce the platelet adhesion and improve cytocompatibility and red blood cell compatibility because of the hydrophobicity and the mushroom-like surface topography [ 62 ].…”

Understanding the mechanism of molecular self-assembly to form well-organized nanostructures is essential in the field of supramolecular chemistry. Particularly, amphiphilic copolymers incorporated with polyhedral oligomeric silsesquioxanes (POSSs) have been one of the most promising materials in material science, engineering, and biomedical fields. In this review, new ideas and research works which have been carried out over the last several years in this relatively new area with a main focus on their mechanism in self-assembly and applications are discussed. In addition, insights into the unique role of POSSs in synthesis, microphase separation, and confined size were encompassed. Finally, perspectives and challenges related to the further advancement of POSS-based amphiphilics are discussed, followed by the proposed design considerations to address the challenges that we may face in the future.

“…Due to their unique properties such as high affinity for water, biocompatibility and tissue‐like properties, hydrogels are used widely in biomedical applications for soft tissue regeneration and drug delivery . In the last decade, polyhedral oligomeric silsesquioxanes (POSS), due to their biocompatibility, high structural stability and ease of surface functionalization, have been used to synthesize a broad range of organic–inorganic hybrid hydrogels using a variety of organic functional groups . POSS nanoparticles with a symmetric cubic cage‐like nanostructure can be incorporated in the structure of hydrogels via chemical and physical crosslinking.…”

[7][8][9][10][11][12][13] POSS nanoparticles with a symmetric cubic cage-like nanostructure can be incorporated in the structure of hydrogels via chemical and physical crosslinking. For example, Zhang and co-workers 14 synthesized thermo-responsive hybrid poly(N-isopropylacrylamide) hydrogels by -ray irradiation with octamethacrylate POSS as a crosslinking agent, and investigated their swelling/deswelling properties.…”

The synthesis is reported of novel hybrid hydrogels based on ethylenediaminetetraacetic acid dianhydride and poly(ethylene glycol) (PEG) with octa‐aminopropyl polyhedral oligomeric silsesquioxane hydrochloride salt (OA‐POSS) as a nano‐crosslinker under solvent‐free conditions. The molecular weight of PEG was varied between 600 and 1000 Da. The synthesized hydrogels were characterized using various techniques. Further, the swelling behavior and antibacterial activity of the hydrogels and release kinetics of metronidazole (MTZ) as a model drug from them were evaluated. Experimental results demonstrate that hydrogels with tunable properties can be synthesized by varying the PEG molecular weight and type of crosslinker (hybrid or organic). Among the synthesized hybrid hydrogels, that crosslinked by OA‐POSS with long PEG chains (1000 Da) showed the highest swelling degree (2000%), drug encapsulation efficiency (88%) and extent of MTZ release (96%). © 2018 Society of Chemical Industry
