Polymeric micelles containing resveratrol: development, characterization, cytot...
Almeida, Tamires Cunha; Seibert, Janaina Brandão; Almeida, Sávio Henrique de Souza; Amparo, Tatiane Roquete; Teixeira, Luiz Fernando de MedeirosAntimicrobial and antitumor activities of resveratrol, a compound found mainly in grapes, have already been demonstrated. However, its low bioavailability is a limiting factor for therapeutic application. Polymeric micelles can be an approach to solve this problem since they can encapsulate hydrophobic substances. We developed and characterized micellar formulations containing resveratrol and evaluated their cy...
Energy transfer in nanostructured films containing poly(p-phenylene vinylene) a...
Postacchini, Bruna Bueno; Zucolotto, Valtencir; Dias, Fernando B.; Monkman, Andy; Oliveira Junior, Osvaldo Novais deThe combination of luminescent polymers and suitable energy-accepting materials may lead to a molecularlevel control of luminescence in nanostructured films. In this study, the properties of layer-by-layer (LbL) films of poly(p-phenylene vinylene) (PPV) were investigated with steady-state and time-resolved fluorescence spectroscopies, where fluorescence quenching was controlled by interposing inert polyelectrol...
