Bioactivity test for amine-based functionalized meso- and macro-porous silicon substrates

Biofunctionalization methods change the bioactive behaviour of the substrates regarding to both Ca-phosphate precipitation and fungi growth. Meso-porous silicon, which is bioactive as raw fresh material, highly improves its bioactivity after biofunctionalization. On the other hand, macro-porous silicon, which shows no bioactivity when tested as fresh material, turns out to be bioactive after biofunctionalization. Fungi development changed in PSi substrates according to the functionalization treatments from promoted growth (immersion) to completely inhibited growth (TA-CVD).
