    PEGylated magnetic nanoparticles and gold nanoparticles are synthesized in situ by complexing metallic precursors with opposite charge containing poly(poly(ethylene glycol) methyl ether methacrylate) grafted copolymers followed by inorganization. The nanoparticles hybrid supramolecular hydrogels with pH and temperature dual responsive are thus prepared by inclusion complexations of the PEGylated nanoparticles and α-cyclodextrins. The hybrid nanoparticles could be released gradually in the presence of water.

    State of the art RDRP and protein/peptide modification methods, have brought synthetic polymer and materials science closer than ever to replicating the precision of nature. The development of aqueous SET-LRP and efficient, highly specific disulfide targeted modifications, using organic arsenicals, furnishes protein-polymer conjugates with unrivalled precision. Continued progress is crucial considering the clear benefits associated with attaching polymers to therapeutic peptides such as oxytocin and polymyxins.

  3. Nonaqueous and Aqueous Emulsion ROMP Reactions Induced by Environment-Friendly Latent Ruthenium Indenylidene Catalyst Bearing Morpholine Substituted Bidentate (N, O) Schiff Bases

    In this study, latent ruthenium metathesis catalysts bearing bidentate Schiff bases are used in nonaqueous emulsion ring-opening metathesis polymerization (ROMP) reactions for the first time and results are compared with aqueous emulsion ROMP reactions. Mn of nanosized polymers are controlled between 115 and 420 kDa yielding polymers with particle sizes of 51–208 nm in nonaqueous emulsion ROMP.

  4. pH-Responsive Aminomethyl Functionalized Poly(p-xylylene) Coatings by Chemical Vapor Deposition Polymerization

    The preparation of a pH-responsive poly(p-xylylene) derivative via chemical vapor deposition polymerization can be achieved by modification of the paracyclophane precursor with ionizable aminomethyl groups. The swelling behavior is investigated using spectroscopic ellipsometry and streaming potential measurements. The capacity regarding the coating of complex substrates with stimuli-responsive films is demonstrated by coating filter paper.

  5. Multifunctional Dendrimer Formation Using Thiolactone Chemistry

    A thiolactone-based strategy is conducted to prepare multifunctional dendrimers. In this context, a thiolactone bearing an isocyanate function is reacted with a hydroxyl terminal groups of a 4-arm poly(ethylene glycol) (step 1). Aminolysis of the thiolactone ring and subsequent thiol-acrylate reaction leads to a double functionalization (step 2). Repetition of steps 1 and 2 leads to the formation of multifunctional dendrimers.
