Journal ArticleDOI
FTIR and Raman Characterization of TiO2 Nanoparticles Coated with Polyethylene Glycol as Carrier for 2-Methoxyestradiol
Andrea León,Patricia Reuquen,Carolina Garín,Rodrigo Segura,Patricio Vargas,Paula A. Zapata,Pedro A. Orihuela +6 more
TL;DR: In this paper, a novel targeting drug delivery system for 2-Methoxyestradiol (2ME) was presented to improve the clinical application of this antitumor drug.
Journal ArticleDOI
Release of silver and copper nanoparticles from polyethylene nanocomposites and their penetration into Listeria monocytogenes
Laura Tamayo,Paula A. Zapata,Nelson Vejar,Manuel Azocar,Miguel Gulppi,Xiaorong Zhou,George Thompson,Franco M. Rabagliati,Maritza Páez +8 more
TL;DR: It was revealed that the antibacterial abilities of the two nanocomposites against L. monocytogenes are associated with both bactericidal and bacteriolytic effects.
Journal ArticleDOI
Nanocomposites based on polyethylene and nanosilver particles produced by metallocenic “in situ” polymerization: synthesis, characterization, and antimicrobial behavior
TL;DR: In this paper, a polyethylene nanocomposites containing silver nanoparticles with antimicrobial properties were produced via in situ polymerization, and the effect of various silver nanoparticle contents on silver ion release and antimicrobial efficacy against Escherichia Coli were studied.
Journal ArticleDOI
Electroactive Smart Polymers for Biomedical Applications.
TL;DR: Details about the ability of these electroactive polymers to mimic muscles by converting electric energy into mechanical energy through an electromechanical response; deliver drugs by changing their internal configuration under an electrical stimulus; and have antimicrobial behavior due to the conduction of electricity, are discussed.
Journal ArticleDOI
Poly(lactic acid)/TiO₂ nanocomposites as alternative biocidal and antifungal materials.
Carmen Fonseca,Almudena Ochoa,María Teresa Ulloa,Eduardo Alvarez,Daniel Canales,Paula A. Zapata +5 more
TL;DR: PLA/TiO2 nanocomposites showed lower shear viscosity than neat PLA, possibly reflecting degradation of the polymer due to the particles, and biocidal properties can be increased under UVA irradiation.
