Abstract
Laser Surface Structuring (LSS) is a well-known technique used to alter the topological and tribological properties of solids, usually to make them more suitable for certain applications. Our aim was to use it on a titanium sample to make it more bio-compatible. We wanted to make our sample more osseointegral, so that it would show better results when placed inside a human body. Research shows that enhancing a substance’s wettability to make it more hydrophilic can produce improve desired qualities such as protein assimilation and cell adhesion. We had one sample of medical grade titanium (Ti6Al4V), which we used a Ti:Sapphire femtosecond laser on to alter its surface properties and wettability. Afterwards, it was observed using FESEM and the sessile drop method, which revealed enhancements in surface roughness and wettability.
