      Article
      Accés restringit per política de l'editorial
      Chitosan is a biodegradable natural polymer with great potential for pharmaceutical applications due to its biocompatibility, high charge density, nontoxicity, and mucoadhesion properties. Processing techniques for the ...

    • One-step sonochemical preparation of redox-responsive nanocapsules for glutathione mediated RNA release 

      Francesko, Antonio; Macedo Fernandes, Margarida Maria; Tzanov, Tzanko; Perelshtein, Illana; Benisvy Aharonovich, Lena; Gedanken, Aharon (Royal Society of Chemistry, 2014-07-09)
      Article
      Accés restringit per política de l'editorial
      Efficient RNA delivery to targeted cells requires the use of stable interactive carriers that provide RNA protection during the extracellular transit and trigger release once internalised. One strategy to avoid the premature ...
