Fig. 3From: Double-edged sword of biofouling potentials associated with haemocompatibility behaviour: titania nanotube arrays for medical implant surface technologyWettability analysis by ImageJ software on the droplet of water on each tested sample. A Image of a droplet of water on the sample Ti and TNA. B histogram of the contact angle values of the wettability profile on surface of Ti and TNA on foil substrate suggests the surfaces presented with hydrophilic properties, WCA < 90°, n = 3.
