Fouling on laser-fabricated model surface reliefs of functional food-industry materials

Abstract A typical food industry material (stainless steel) was laser-textured to evaluate biofouling of model surface relief. Both initial and laser-textured surfaces were characterized by scanning electron microscopy, energy-dispersive x-ray radiation, Raman spectroscopy, and scanning probe microscopy to reveal the most important pre-requisites for their biofouling by food pathogen bacteria.
