However, the main category of antimicrobials includes \cite{Cloutier2015}:
          ●          Disinfectants that destroy numerous microbes on non-living surfaces to prevent the spread of infections and diseases
          ●          Antiseptics that are applied over living tissue to prevent infections
          ●          Antibiotics that protect against microbial attack inside the body
Antimicrobials can be microbicidal and biostatic. Like the earlier definition for antibacterial agents, microbicidal agents are those that destroy microbes, while biostatic are the ones that stop their growth.
