Abstract
Polyrotaxanes (PRXs) containing acetylated α-cyclodextrins exhibit a temperature-dependent phase transition in aqueous solutions across their lower critical solution temperature (LCST) of approximately 26.6 °C. To gain insights into the interactions of acetylated PRXs (Ac-PRXs) with biological components, thermoresponsive supramolecular surfaces were prepared by coating tissue culture polystyrene (TCPS) surfaces with Ac-PRX triblock copolymers, and their surface properties across the LCST were evaluated. The wettability and protein adsorption of Ac-PRX-coated surfaces changed significantly between 10 and 37 °C, whereas the uncoated TCPS and unmodified PRX-coated surfaces did not alter the wettability and protein adsorption at 10 and 37 °C. The adhesion, proliferation, morphology, and adhesion strength of NIH/3T3 cells on Ac-PRX-coated surfaces were found to be similar to those of the uncoated and unmodified PRX-coated surfaces. However, the adhesion strength of NIH/3T3 cells on Ac-PRX-coated surfaces decreased drastically at 10 °C. Consequently, the cells spontaneously detached from the Ac-PRX-coated surfaces without enzymatic treatment. Additionally, when incubating confluent cells at 10 °C, the cells detached from Ac-PRX-coated surfaces as cell sheets while retaining extracellular matrix proteins. The findings of this study provide new directions for the design of thermoresponsive supramolecular biointerfaces for applications in bioseparation and cell manipulation.

Abstract
Polyrotaxanes are supramolecular assemblies consisting of cyclic molecules (e.g., α-cyclodextrins) and linear polymer chains (e.g., poly[ethylene glycol]), in which cyclic molecules can move along the polymer chain. Here, we examined the effect of functional groups introduced into the α-cyclodextrins of polyrotaxane on cell responses such as adhesion, proliferation, and differentiation. Polyrotaxane-based triblock copolymers modified with methyl (CH3, hydrophobic, and nonionic), hydroxy (OH, hydrophilic and nonionic), amino (NH2, cationic), and sulfo (SO3H, anionic) groups were coated on the surface of the culture plate to fabricate polyrotaxane surfaces with different surface chemistries. The chemical compositions of each surface were determined via time-of-flight secondary ion mass spectrometry and X-ray photoelectron spectroscopy. The contact angle hysteresis reflecting the molecular mobility and zeta potential of each polyrotaxane surface changed depending on the functional groups. When osteoblast and adipocyte differentiation was induced in human mesenchymal stem cells cultured on each polyrotaxane surface, the cells adhered to the SO3H-modified polyrotaxane surfaces exhibited osteoblast differentiation, whereas the cells adhered to the OH-, NH2-, and SO3H-modified polyrotaxane surfaces preferentially underwent adipocyte differentiation compared with those on the unmodified and CH3-modified polyrotaxane surfaces. Interestingly, the SO3H-modified polyrotaxane surfaces promoted both osteoblast and adipocyte differentiation. High molecular mobility and negative charge on the SO3H-modified polyrotaxane surfaces are expected to contribute to the facilitation of both osteoblast and adipocyte differentiation.

Abstract
A polyrotaxane (PR) with poly(methyl methacrylate) (PMMA) as the main chain polymer was prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization. Because of the special mechanism of RAFT, the suprastructure of a PMMA-based PR is established by synthesizing inclusion complexes of methyl methacrylate and gamma-cyclodextrin (γCD) into the middle of the poly-N-(3-dimethylamino) propyl methacrylamide segments. The presence of threaded γCD was determined via diffusion ordered spectroscopy from the alignment of the mobility of γCD and the main chain polymer. A PMMA-based PR with 2-20% CD coverage and a molecular weight of 7K-60K g/mol of PMMA-based PR was synthesized with a targeted molecular structure by mediating the RAFT polymerization. The PMMA-based PR prepared in this study is expected to be suitable for wide applications of tough materials with good heat resistance. Moreover, the investigation of this synthetical approach opened possibilities for more variety of PR with controllable properties.

Abstract
Hydrogels have long been explored as attractive materials for biomedical applications given their outstanding biocompatibility, high water content, and versatile fabrication platforms into materials with different physiochemical properties and geometries. Nonetheless, conventional hydrogels suffer from weak mechanical properties, restricting their use in persistent load-bearing applications often required of materials used in medical settings. Thus, the fabrication of mechanically robust hydrogels that can prolong the lifetime of clinically suitable materials under uncompromising in vivo conditions is of great interest. This review focuses on design considerations and strategies to construct such tough hydrogels. Several promising advances in the proposed use of specialty tough hydrogels for soft actuators, drug delivery vehicles, adhesives, coatings, and in tissue engineering settings are highlighted. While challenges remain before these specialty tough hydrogels will be deemed translationally acceptable for clinical applications, promising preliminary results undoubtedly spur great hope in the potential impact this embryonic research field can have on the biomedical community.

Abstract
Reversible covalent bonds yield polymeric materials with functional characteristics such as self-healing, shape memory, stress relaxation, and stimuli-responsiveness. Here, photo-reversibly cappable polyrotaxanes are designed and the on-off controlled dissociation of their supramolecular architectures is demonstrated. The polyrotaxanes are synthesized by capping dithiobenzoates at both terminals of polyethylene glycol threaded through multiple α-cyclodextrins. Since dethreading of the α-cyclodextrins is prevented by the dithiobenzoate stoppers, the supramolecular dissociation is induced by their photo-cleavage. Subsequently, the cleaved dithiobenzoates spontaneously re-cap the polyrotaxane terminals in darkness. Thus, the supramolecular dissociation can be modulated by photo-reversible capping of the dithiobenzoate stoppers. These polyrotaxanes with dithiobenzoate stoppers are promising functional materials for photo-controlling physical properties and structures.

Abstract
The use of natural compounds to construct biomaterials, including delivery system, is an attractive strategy. In the present study, through threading functional α-cyclodextrins onto the conjugated macromolecules of poly(ethylene glycol) (PEG) and natural compound bile acid, glycopolymers of polyrotaxanes with the active targeting ability are obtained. These glycopolymers self-assemble into micelles as evidenced by dynamic light scattering and transmission electron microscopy, in which glucosamine, as an example of targeting groups, is introduced. These micelles after loading doxorubicin (DOX) exhibit the selective recognition with cancer cells 4T1. Meanwhile, the maximal half inhibitory concentration is determined to be ≈2.5 mg L-1 for the DOX-loaded micelles, close to the value of free DOX·HCl (1.9 mg L-1 ). The cumulative release of DOX at pH 5.5 is faster than at pH 7.4, which may be used as the controlled release system. This drug delivery system assembled by glycopolymers features high drug loading of DOX, superior biocompatibility. The strategy not only utilizes the micellization induced by bile acids, but also overcomes the major limitation of PEG such as the lack of targeting groups. In particular, this drug delivery platform can extend to grafting the other targeting groups, rendering this system more versatile.

Abstract
The aqueous reversible addition fragmentation chain-transfer (RAFT) copolymerization of isoprene and bulky comonomers, an acrylate and an acrylamide in the presence of methylated β-cyclodextrin was employed for the first time to synthesize block-copolyrotaxanes. RAFT polymerizations started from a symmetrical bifunctional trithiocarbonate and gave rise to triblock-copolymers where the outer polyacrylate/polyacrylamide blocks act as stoppers for the cyclodextrin rings threaded onto the inner polyisoprene block. Statistical copolyrotaxanes were synthesized by RAFT polymerization as well. RAFT polymerization conditions allow control of the composition as well as the sequence of the constituents of the polymer backbone which further effects the CD content and the aqueous solubility of the polyrotaxane.

Abstract
Cyclodextrin (CD)-threaded polyrotaxanes (PRXs) with reactive functional groups at the terminals of the axle polymers are attractive candidates for the design of supramolecular materials. Herein, we describe a novel and simple synthetic method for end-reactive PRXs using bis(2-amino-3-phenylpropyl) poly(ethylene glycol) (PEG-Ph-NH2) as an axle polymer and commercially available 4-substituted benzoic acids as capping reagents. The terminal 2-amino-3-phenylpropyl groups of PEG-Ph-NH2 block the dethreading of the α-CDs after capping with 4-substituted benzoic acids. By this method, two series of azide group-terminated polyrotaxanes (benzylazide: PRX-Bn-N3, phenylazide: PRX-Ph-N3,) were synthesized for functionalization via click reactions. The PRX-Bn-N3 and PRX-Ph-N3 reacted quickly and efficiently with p-(tert-butyl)phenylacetylene via copper-catalyzed click reactions. Additionally, the terminal azide groups of the PRX-Bn-N3 could be modified with dibenzylcyclooctyne (DBCO)-conjugated fluorescent molecules via a copper-free click reaction; this fluorescently labeled PRX was utilized for intracellular fluorescence imaging. The method of synthesizing end-reactive PRXs described herein is simple and versatile for the design of diverse functional PRXs and can be applied to the fabrication of PRX-based supramolecular biomaterials.
