Influencia de la nitruración iónica en la respuesta hemocompatible de aceros inoxidables austeníticos
(2015)
El acero 316L es un metal que se emplea frecuentemente en la fabricación de implantes biomédicos, y sus características y propiedades superficiales pueden ser alteradas positivamente mediante el uso de técnicas que cambian ...
Caracterização física do carbono pirolítico utilizado na produção de próteses valvulares cardiácas mecânicas
(Universidade Federal de Minas GeraisUFMG, 2002-11-09)
In this work we study the mechanical end microestrutural proprieties of pyrolytic carbon (PyC) used in the fabrication of heart valves. This material has low corrosion and oxidation rates, high biocompatibility and chemical ...
Nanotoxicological assessment of functionalized rare earth nanoparticles for bioimaging of cancer cells
(2020-12)
In the field of biomedicine, nanotechnology is providing new tools for imaging and diagnosis through the synthesis and tuning of new nanomaterials with unique physicochemical properties. Among others, luminescence upconversion ...
Fabrication of Tio2 crystalline coatings by combining Ti-6Al-4V anodic oxidation and heat treatments
(Hindawi Publishing Corporation, 2015-01)
The bio- and hemocompatibility of titanium alloys are due to the formation of a TiO2 layer. This natural oxide may have fissures which are detrimental to its properties. Anodic oxidation is used to obtain thicker films. ...

Chitosan-hydroxypropyl methylcellulose tioconazole films: A promising alternative dosage form for the treatment of vaginal candidiasis
(Elsevier Science, 2019-02-10)
Vaginal candidiasis is considered a frequent opportunistic mucosal infection and the second most common cause of vaginitis after bacterial vaginosis. In this work, different vaginal films based on chitosan, hydroxypropyl ...
Nanotoxicological study of downconversion Y2O3:Eu3+luminescent nanoparticles functionalized with folic acid for cancer cells bioimaging
(2020-01)
Luminescent lanthanide downconversion nanoparticles (DCNPs) provide a combination of high luminescence intensity, sharp emission peaks with narrow bandwidth and a large Stokes' shift, leading to high‐performance biomedical ...
