Erythrocyte Membrane Surface after Calibrated Electroporation: Visualization by Atomic Force Microscopy

Abstract: Atomic force microscopy was used for examination of the surface of human erythrocyte membrane after calibrated electroporation and application of pharmacological agents. Three-order surface inhomogeneities were revealed with various spectral windows of Fourier transform to elaborate the quantitative criteria to assess the state of membrane surface. The size of structural alterations induced in the membranes by electroporation was 100-300 nm, which is comparable to the size of membrane matrix.

“…Utiliza-se este último nome, pois foi creditado a formação de poros na membrana, após a exposição ao campo elétrico, a razão do aumento de permeabilidade na membrana. Embora não existam evidencias físicas que poros são criados na membrana da célula(CHANG; REESE, 1990;CHERNYSH et al, 2009) vez que os mecanismos de manutenção de vida da célula são dependentes de seus estoques (TSONG, 1991;KANDUSER et al, 2006;DANDO;.…”
