  • Core@shell nanostructures for photothermal conversion: Tunable noble metal nanoshells on Cross-Linked Polymer submicrospheres
    Journal of Materials Chemistry, 2010
    Co-Authors: Junfeng Zhou, Lingjie Meng, Qinghua Lu
    Abstract:

    Highly Cross-Linked and monodispersed poly(cyclotriphosphazene-co-4,4′-sulfonyldiphenol) (PZS) submicrospheres were synthesized by one-step polycondesation. The spheres are enriched in N, P, and S atoms, and phenolic hydroxyl groups, and exhibit good water dispersion. These properties facilitate initial growth of gold nanoseeds on the PZS surface and subsequent growth of gold nanoshells. This facile fabrication method can also be used for the preparation of silver and gold–silver bimetallic nanoshells with tunable thickness by varying the mass ratio of metal salt to PZS. The core@shell structures were investigated by transmission electron microscopy, energy-dispersive X-ray spectrometry, selected-area electron diffraction and X-ray diffraction analysis. PZS@gold nanoshells showed very strong surface plasmon resonance absorption in the near infrared region (700–1100 nm), where blood and biological tissues are nearly transparent. Furthermore, PZS@gold nanoshells effectively induced photothermal conversion under laser irradiation of 808 nm and rapidly killed tumor cells, suggesting potential application in photothermal imaging and therapies using NIR lasers.

  • Reversibly Cross-Linked Polymer Gels as Healing Agents for Epoxy-Amine Thermosets
    ACS Applied Materials & Interfaces, 2009
    Co-Authors: Amy M. Peterson, Robert E Jensen, Giuseppe R Palmese
    Abstract:

    The Diels−Alder reaction was used to develop a reversibly cross-linking gel as a healing agent for traditional epoxy−amine thermosets. Direct application of the reversibly cross-linking network to a crack surface in an epoxy−amine thermoset resulted in the recovery of 37% of the initial epoxy−amine network’s strength. Composites in which the reversibly cross-linking gel was incorporated as a secondary particulate phase recovered 21% of the initial composite strength after the first healing cycle, with healing possible up to five times.

  • Recent progress in designing shell Cross-Linked Polymer capsules for drug delivery
    RSC Advances, 2015
    Co-Authors: Beata Miksa
    Abstract:

    This tutorial review highlights the progress made during recent years in the development of the shell Cross-Linked (SCL) Polymer nanocapsules and the impact of the most important scientific ideas on this field of knowledge. More precisely, it provides some guidelines towards the innovative design of SCL Polymer capsules and presents different methods that have been used so far. It also includes the discussion on the major topics of stimuli-responsive moieties incorporated into spherical hollow Polymer nanostructures. A wide variety of light and pH-responsive compounds together with synthetic strategies which enable introducing them in defined locations of macromolecular architectures are illustrated in this article. Moreover, this tutorial explains diverse methodologies for classifying the manifold formations of vesicular systems that allow for the preparation of SCL Polymer capsules based on the general approach concerning the organization of Polymers into well-defined vesicular assemblies followed by stabilization through covalent cross-linking.
