Bio-compatible materials

Laser-induced surface modification technique can be adopted for manufacturing of bio-compatible substrates (ceramics and polymers) featuring periodic sub-micrometer spaced gratings, or surface ripples. These structures are produced by near-threshold irradiation of materials with tightly focused ultrafast laser radiation. Combined with multiple beam interference technique, this approach can produce surface modifications used for directional cell growth with highly promising applications in medicine and biology. For example surfaces of implants can be functionalized adopting this technique for muscle or nerve cell therapy.
