Laser-Induced Surface Texturing and Functionalization for Antibacterial Applications

Ultra-short femtosecond (fs) lasers have emerged as a powerful tool for the fabrication of micro- and nano-patterned surfaces, offering exceptional precision and minimal thermal impact on materials. To address the challenge of bacterial contamination on frequently touched surfaces, femtosecond laser processing provides a promising, non-destructive approach for creating hierarchical micro/nano-structures. By inducing controlled groove-like textures on metals and polymers, it is possible to tailor surface roughness characteristics that influence bacterial adhesion behavior. Variations in surface morphology—particularly in terms of feature height and spacing—play a crucial role in determining bactericidal efficiency. Thus, laser-induced surface texturing offers a purely geometrical route to modulate bacterial attachment without the need for chemical treatment or coatings.
