Fig. 4From: Double-edged sword of biofouling potentials associated with haemocompatibility behaviour: titania nanotube arrays for medical implant surface technologyA Haemolytic assay of Ti and TNA surfaces. Image of samples after the centrifugation at 2500 rpm for 5 min. The presence of haemolysis in the supernatant is only observed in the positive control tube. B Haemolysis ratio profile of Ti and TNA surfaces. Results indicate there is no significant differences in all the period tested which is 30, 180 and 360 min which compared for both material surfaces (Ti and TNA) where the p-value is > 0.05. The error bar represents mean ± standard deviation in triplicate within three donorsBack to article page
