The sample was then rinsed with 10% HF + 40 % HNO3 + 50% H2O, ultrasonic-cleared in acetone, dried, oxygenized in H2O2, rinsed, dried, sterilized, and lixiviated. L-929 cells were cultured in vitro and assigned into negative control, surface oxidation (surface oxidation + NiTi-SMA leaching liquor), and non-treatment groups (NiTi-SMA leaching liquor alone).
