SUMMARY:Séminaire Fernando Giacomelli
DESCRIPTION:\nCentro de Ciências Naturais e Humanas, Universidade Federal do ABC, Santo André, Brazil\n\n\n\nTailoring Polymer Colloids through Supramolecular Interactions:Polymersomes, Polyplexes and Polymer-Metal Hybrids towards a Toolbox for Nanofactories and Nanotherapeutics\n\n\n\n\n\n\n\nPolymer colloids are complex materials with versatile structures and morphologies that have the potential to be used in a wide array of fields. In this regard, structural changes of polymeric assemblies can be induced by disparate environmental conditions found in biosystems and therefore, such responsive platforms with tunable properties are attractive for applications in life sciences. Accordingly, this speech aims to disseminate the recent findings of the research group in this framework, particularly focusing on three different subjects: i) investigations concerning the permeability of polymersomes towards the manufacturing of nanofactories for biotransformations,[1,2] ii) manufacturing of environmentally-responsive supramolecular assemblies for the delivery of molecular and macromolecular therapeutics[3-5] and iii) the formation of biomacromolecular coronas when nanomaterials are swimming in protein environments.[6,7]\n\n\n\n\n\n\n\n 1.          Du, H. et al.
