Abstract

The interaction of spherical gold nanoparticles (AuNPs) of 20nm elaborated by Turkevich method with the erythrocytes ghosts (7-8 μm) cell membrane was evaluated. The AuNPs-Membrane interaction was determined using confocal microscope, Uv-Vis spectroscopy and SEM analysis. The result show that nanoparticles larger than 20nm are adhered to the erythrocyte ghost membrane due their size and surface modification. Smaller AuNPs enter onto the cell by simple diffusion through the plasmatic membrane voids, these data may favor the best design and application in the treatments applied in biomedicine.
