Beschreibung
Zusammenfassung:	Systems and methods are provided for generating microscale structures and/or nanoscale structures, surface profiles, and surface chemistries on medical devices. Embodiments disclosed herein utilize exposure of pulsed laser radiation on to a surface of a material by a pulsed laser. The pulsed laser according to embodiments disclosed herein is configured to emit at least one laser pulse toward the surface and thereby modify the profile of the surface in order to selectively promote or inhibit bioactivity and medical functionality of the material. By selectively promoting or inhibiting bioactivity of the material, enhanced biointegration at a cellular level may be achieved. For example, modifying the surface profile and/or surface chemistry of a first substrate material can improve adhesive and/or chemical bonding of the first material to a bioactive second coating material.
