Resumo
Bioaccumulation in sanitary devices, caused by opportunistic pathogens,
intervenes negatively in the recovery of a patient since these are able to provoke a mild
or life-threatening infection. Thus, surfaces of certain materials such as gauzes,
catheters, sutures, etc., which are adjacent or directly exposed to a healing zone, are
prone to become sites for the growth, proliferation, and spread of pathogenic
microorganisms. Although in surgical or healing processes, sterile materials are usually
applied, the time of contact with biological interfaces is long enough to make the
sterilization but not enough to control and prevent an infection since pathogens abound
in the surroundings. Air, water, and soil can be potential vectors, without considering
those factors related to iatrogenesis that also play a role in the opportunities for the
patient's recovery. Within this context, engineered materials are currently being
developed and explored towards devices and biomaterials with improved design,
performance, duration, biocompatibility aiming to be safer for the user. The surface
functionalization of materials with antimicrobial agents is a highlighted alternative to
overcome this issue. This chapter addresses current antimicrobial materials, as well as
strategies for obtaining antimicrobial surfaces and coating as well as their properties. In
addition, the safety assessment of biomedical applications and international standards
are discussed.
