Abstract
Different types of polymer chains generated during the nitroxide-mediated polymerization of styrene are separated for the first time, and their molecular weight distribution (MWD) is investigated. Living and dead chains are monitored during the reaction; specifically, two types of living chains derived from the initiation of the alkoxyamine (RT) and the self-initiation of styrene and dead chains present in the as-prepared polystyrene (PS). To distinguish between each polymer species, different numbers of hydroxyl groups are introduced onto the T and R groups of the alkoxyamine (one and two groups, respectively). Each living and dead chains is resolved according to the distinct number of hydroxyl groups on its chain-end using high-performance liquid chromatography. Molecular structures of the fractionated PS are characterized using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 1 H nuclear magnetic resonance spectroscopy, and the results of which show two distinct initiation paths: one originating from RT and the other from the self-initiation of styrene. Molecular weight and MWD are measured using size-exclusion chromatography and reveal a narrow MWD for the living chains derived from RT. Contrastingly, a broad and skewed MWD is observed for the other living chains derived from the self-initiation of styrene and the dead chains.

Abstract
Thermo-responsive block copolymers are of great interest in biomedical and nanotechnological fields. These polymers achieve a versatile and complex responsiveness through a sophisticated and intricate combination of different thermo-responsive blocks. While their utility is clear, the fundamental design principles of such vinyl polymers are not yet thoroughly understood. Herein, a precise synthesis of sequence-controlled amino-acid-derived vinyl polymers and their unique thermal response in water are reported. Seven distinct block (random) copolymers that contain two kinds of amino acid blocks (poly(N-acryloyl alanine(A)- or glycine(G)-methyl ester)) with the same total chain length (degree of polymerization [DP] ≈30) and chemical composition (A/G ≈1), but with systematic variations in the block sequence and length, with an accuracy target of DP ± 1, are prepared. By specifying the primary structure, the thermal responses including transition temperature, thermo-sensitivity, and microenvironment in the dehydrated state can be finely tuned. These findings offer new directions in the design of structurally and functionally diverse thermo-responsive vinyl polymers.

Abstract
Controlling the surface properties of engineered materials to enhance or reduce their cellular affinities remains a significant challenge in the field of biomaterials. We describe a universal technique for modulating the cytocompatibilities of two-dimensional (2D) and three-dimensional (3D) materials using a novel photocleavable peptide-grafted poly(2-hydroxyethyl methacrylate) (PHEMA) hybrid. The reversible addition-fragmentation chain transfer copolymerization of HEMA and propargyl acrylate was successfully controlled. The resultant alkyne-containing PHEMA was then used to modify the azide-terminated oligopeptides [Arg-Gly-Asp-Ser (RGDS)] with a photolabile 3-amino-3-(2-nitrophenyl)propanoic acid moiety via the copper-catalyzed alkyne-azide click chemistry. This strategy was readily used to decorate the surfaces of both hydrophilic and hydrophobic materials with RGDS peptides due to the high film-forming abilities of the PHEMA unit. The resultant thin film acted as an effective scaffold for improving cell adhesion and growth of NIH/3T3 fibroblasts and MC3T3-E1 osteoblast-like cells in vitro. In addition, UV irradiation of the surface led to the detachment of cells from the material surface accompanied by the photocleavage of RGDS grafts and enabled the 2D-patterning of cells and cell sheet engineering. The applicability of this system to 3D materials was investigated, and the cell adhesion was remarkably enhanced on a 3D-printed poly(lactic acid) object. This facile, biocompatible, and photoprocessable peptide-vinyl polymer hybrid system is valuable for its ability to advance the fields of tissue engineering, cell chips, and regenerative medicine.

Abstract
Novel polymeric nanoparticles (NPs) with uniform sizes were prepared from peptide-vinyl polymer diblock hybrids by the self-organized precipitation method. Hybrid polymers of polystyrene (PSt) and tetrapeptide (cell-binding epitope RGDS, reverse SDGR, cationic KKKK, and anionic DDDD) were successfully synthesized by combining solid-phase peptide synthesis and reversible addition fragmentation chain transfer polymerization methods. Narrowly dispersed hybrid polymers (polydispersity index < 1.25, M n 14 000-17 000) were obtained. Altering the preparation conditions easily tuned the size and size distribution of the NPs. When the ζ-potentials for the NP suspensions were measured at pH 6.0, the obtained values corresponded to the net charge of each peptide segment. More importantly, the NPs could encapsulate fluorescent Nile red (NR) and magnetic iron oxide NP (MNP), which might be suitable for fluorescent imaging and magnet-induced patterning of cells, respectively. The interactions of NPs with cells (NIH/3T3 fibroblast) and the magnetic effects were examined for NR/MNP-loaded PSt-RGDS and -SDGR NPs. Both NPs were readily incorporated into cells, but only NR/MNP-loaded PSt-RGDS NP showed magnetic responsiveness in cell adhesion and cultures.
