ESTUPINAN DURAN, HUGO ARMANDO; PENA BALLESTEROS, DARIO YESID  e  VASQUEZ QUINTERO, CUSTODIO. OSTEOBLAST ADHESION ON SCAFFOLDS OF PLA-PLG-HYDROXYAPATITE-CHITOSAN-ZINC BY ELECTROACTIVATION. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.176, pp.99-104. ISSN 0012-7353.

This paper presents results of the study of the phenomenon of electroactivation of system cell- polylactic acid (PLA) and polyglycolic acid (PLG) with additions of bioactive elements of chitosan (q), bioceramic (bc), and zinc. The main purpose is to explain the increase in the adhesion of cells as a result of the change in the hydrophilicity of a cell regeneration matrix and the variation in intracellular ion exchange, induced by the application of electric overpotential and bioactive element additions to the polymers.

Palavras-chave : electroactivation; scaffold; impedance; bioactivity.
