Resumo
Surfaces of pure titanium and Ti coated with cellulose acetate propionate (CAP) have been characterized by
means of scanning electron microscopy X ray coupled with elemental microanalysis (SEM-EDS), ellipsometry,
atomic force microscopy (AFM) and contact angle measurements. Coating Ti surfaces with CAP ultrathin films
reduced original surface roughness. Surface energy and wettability of CAP covered Ti surfaces pure Ti surfaces
were similar. The adsorption of lysozyme (LYZ), an antibacterial protein, onto Ti and CAP-coated Ti surfaces has
been studied by means of ellipsometry and atomic force microscopy (AFM). The adsorption of LYZ was mainly
driven by hydrophobic interaction between protein hydrophobic residues and CAP propyl groups. Pure Ti and
CAP coated Ti surfaces presented no cytotoxicity effect and proved to be adequate substrates for cell adhesion.
The biocompatibility of CAP coated Ti surfaces was attributed to the surface enrichment in glucopyranosyl
residues and short alkyl side groups.
