Functional hydrogels that can be obtained through facile fabrication procedures and subsequently modified using straightforward reagent-free methods are indispensable materials for biomedical applications such as sensing and diagnostics. Herein, a novel hydrogel platform is obtained using polymeric precursors containing maleimide functional group as side chain. The maleimide groups play a dual role in fabrication of functional hydrogels. They enable photochemical crosslinking of the polymers to ...

Incorporation of a therapeutic antibody into nanosized drug delivery systems can improve their target specificity. This work reports an antibody-conjugated targeted delivery system composed of polymer-dendron conjugates. Trastuzumab is chosen as the targeting moiety, since it is clinically used against tumor cells expressing HER2 receptors. A micellar delivery system was generated using amphiphilic polymer-dendron conjugates containing a fourth-generation polyester dendron as the hydrophobic blo...

Herein, we report a synthetic approach to thiol-reactive polymers containing methanethiosulfonate groups as side chains, and demonstrate their application in post-polymerization functionalization through reversible disulfide linkages. A novel methane-thiosulfonate group containing methacrylic monomer was synthesized and copolymerized with hydrophilic poly(ethylene glycol)methyl ether methacrylate (PEGMEMA) monomer using reversible addition–fragmentation chain transfer (RAFT) polymerization. Poly...

Recent advancements in synthesis of hydrogels containing cyclodextrin (CD) units within the gel network have been reviewed. These cyclic polysaccharides augment the properties of hydrogels, an indispensable class of polymeric materials that find applications in various areas of materials and biomedical sciences. CDs are of great interest in biomedical applications due to their versatile characteristics including low toxicity, bioavailability, biodegradability and most importantly their capabilit...

In this work, metal-to-dielectric contact-separation type triboelectric nanogenerators (TENG) are realized using polydimethylsiloxane (PDMS) and steel to harvest energy from daily motions with frequencies of around 1 Hz. A novel polymer modified PDMS has been used as the active material of the TENG device to extend the triboelectric properties of the traditional PDMS. For this purpose, PDMS is functionalized with polystyrene (PS) and poly(pentafluorostyrene) (PPFS) using batch-fabrication compat...

A modular platform for the separation and purification of lectins using polymer coated iron oxide nanoparticles is developed. Supramolecular host–guest interactions based on an adamantane beta-cyclodextrin (β-CD) dyad are utilized to modify the polymeric interface. Poly(ethylene glycol) based hydrophilic polymer-coated magnetic iron oxide nanoparticles are fabricated using reversible addition–fragmentation chain transfer polymerization, followed by their chain-end modification to install adamant...

Infection associated with surgical implants is a major cause of their failure. Often in such cases, the implant has to be removed and replaced, which causes undesirable patient discomfort and complications. Bacterial adhesion and growth on implant surface is the primary reason for such infections. Among the approaches to prevent implant associated infections, the conjugation of antimicrobial peptide (AMP) onto the surface of the implant is a very promising approach. In this study, we describe a ...

Among various nanomedicine platforms, biodegradable polymeric micelles offer a viable approach to targeted cancer therapy. Herein, we report fabrication of core-cross-linked micelles using dendron–polymer conjugates as building blocks. Hydrophobic polyester dendrons containing peripheral alkene groups are conjugated to a hydrophilic poly(ethylene glycol) based copolymer bearing activated ester groups for appending an amine-containing peptide based targeting group, namely, cRGDfK. Micellar constr...

Multifunctionalizable polymeric nanofibers can be tailored for various biomedical applications by selective conjugation of small molecules and bioactive ligands. This study reports the design, synthesis, and application of novel biodegradable polyester-based nanofibers bearing metal-free “clickable” handles. Polylactide-based polymers were synthesized using organo-catalyzed ring-opening polymerization to contain “clickable” chain-end functional groups that specifically react through radical or n...

Photosensitizing nanogels were obtained through a surfactant-free single-step protocol by using a porphyrin-based cross-linker for stabilizing self-assembled nanosized aggregates of thermoresponsive copolymers. Nanogels with varying amounts of porphyrin retained the singlet oxygen generation ability of the porphyrin core and were also capable of inducing temperature increase upon irradiation at 635 nm. Photoinduced killing efficiency was tested against three cell lines: human breast adenocarcino...
