Ligas de titânio são amplamente utilizadas na reparação de tecido ósseo devido suas excelentes propriedades de volume. Neste estudo foram analisado o potencial bactericida de tratamentos de superfície na liga Ti7,5Mo. As amostras foram anodizadas em NH4F/H2O/glicerol para crescimento de nanotubos de TiO2, posteriormente foram cobertas com uma manta de PCL eletrofiado e realizado a incorporação de clorexidina por dois métodos, imersão e gotejamento. A superfície foi analisada por microscopia eletrônica de varredura e medidas de ângulo de contato. O efeito bactericida foi analisado por meio da cultura de C. albicans e S. aureus. A incorporação por imersão apresentou resultados mais satisfatórios.Descritores: Materiais Biocompativeis; Titânio; Ligas; Nanotubos; Propriedades de Superfície.
