Evaluation of Streptococcus mutans Adhesion to Stainless Steel Surfaces Modified Using Different Topographies Following a Biomimetic Approach

Bacterial adhesion to surfaces is the first step in biofilm formation, which leads development of conditions that may compromise health status patients. Surface modification has been proposed reduce bacterial biomaterials. The objective this work was assess and compare Streptococcus mutans surface biomimetically-modified stainless steel using different topographies. Stainless plates were modified a soft lithography technique following biomimetic approach. leaves from Colocasia esculenta, Crocosmia aurea Salvinia molesta used as models. Silica sol synthesized sol-gel method. Following technique, transferred SS plates. Natural characterized by means atomic force microscopy contact angle. adhesion. Contact angle measurements showed natural are highly hydrophobic, but such hydrophobicity could not be metallic Roughness varied among increased after transference for C. esculenta decreased aurea. In general, two models investigation positive results reduction (C. esculenta), while other an increase (S. molesta). Therefore, since approach opposite results, careful selection model needs taken into consideration.
