Journal ArticleDOI
Active polylactic acid film incorporated with green tea extract: Development, characterization and effectiveness
Cristiana Martins,Fernanda Vilarinho,Ana Sanches Silva,Mariana Andrade,Ana Vera Machado,M. Conceição Castilho,Arsénio Vasconcelos Sá,Américo Cunha,M. Fátima Vaz,Fernando Ramos +9 more
TL;DR: A new antioxidant active packaging film has been developed based on polylactic acid (PLA) in which green tea extract (GTE) has been immobilized by extrusion as mentioned in this paper.
Book ChapterDOI
Bioplastics from agro-wastes for food packaging applications
TL;DR: In this article, the preparation of new functional biopolymers for packaging based on extracted cellulose, which exhibits broadly tunable thermomechanical properties and biodegradation, is discussed.
Journal ArticleDOI
Thermodynamic stability and relaxation studies of small, triaza-macrocyclic Mn(II) chelates
Arsénio Vasconcelos Sá,Célia S. Bonnet,Carlos F. G. C. Geraldes,Éva Tóth,Paula M. T. Ferreira,João P. André +5 more
TL;DR: The synthesis and characterization of three new triazadicarboxylate-type ligands and their Mn(2+) chelates and their thermodynamic stability is lower than that of the corresponding NOTA analogues, consistent with the decreased number of coordinating carboxylates groups.
Journal ArticleDOI
Gallium labeled NOTA-based conjugates for peptide receptor-mediated medical imaging.
Arsénio Vasconcelos Sá,Áurea A. Matias,M. Isabel M. Prata,Carlos F. G. C. Geraldes,Paula M. T. Ferreira,João P. André +5 more
TL;DR: The (67)Ga-labeled conjugates proved to have high kinetic stability and showed a weak but specific binding to the receptors in a U87MG-glioblastoma cell line.
Journal ArticleDOI
Triaza-based amphiphilic chelators: Synthetic route, in vitro characterization and in vivo studies of their Ga(III) and Al(III) chelates
TL;DR: The synthesis and in vitro and in vivo studies of a series of micelles-forming Ga(III) chelates targeted for the liver are described, showing higher liver uptake for [(67)Ga](NOTAC8) in comparison to [(67]Ga]( NOTAC6), consistent with a longer alpha-alkyl chain and a higher lipophilicity.
