Ultra-fast Laser Surface Functionalization for Antibacterial and Medical Applications

Organizers

Laura Gemini, ALPHANOV, France

 

Laser-based surface functionalisation has become nowadays a complementary technology to traditional coating deposition techniques thanks to the current readiness of the ultra-fast laser technology which allows for high throughput processing of all kinds of materials, such as metals, dielectrics, composites and so on. The advantages of such approach are well known: laser processing is a one-step technique which allows to functionalise directly the bulk material without the use of any chemical additive, increasing the overall lifetime of the functionalised surface and reducing the related cost importantly. One of the property which can be tailored through this technique is the proneness of bacteria to adhere to the surface, as well as its wettability to water or other liquids. Several studies can be found in literature demonstrating the possibility to produce antibacterial surfaces with high throughput processing (texturing speed > tens of cm2/s) on steel, transparent materials and several polymers by successive injection moulding. The collaboration between a specific surface morphology and wettability allows for optimisation of the antibacterial behaviour towards specific bacteria or biofilm. These functionalised surfaces find applications in several environments and industrial sectors, as for instance in food processing, home appliances, building, automotive and of course the biomedical industry. Applications to biomaterials and medical devices extend even further thanks to an additional properties of laser-based functionalised surfaces to promote cell adhesion and integration. This behaviour was reported on medical grade Ti alloys and ceramics employed for medical implants as well as on biocompatible polymers. One of the last challenges of the use of laser-based surface functionalisation for improved osseointegration is to application of these techniques directly on bone tissue or engineered tissues with the goal of reducing the healing time for bone surgery patients. While this particular application is very recent and still under evaluation, it already showed promising results.
