ABSTRACT
This chapter provides an overview of the most recent research efforts in the definition of antibacterial strategies against bacterial resistance through nanotechnology and biotechnology approaches, with a special focus on the huge potential of metal nanoparticles and their possible combination with antibacterial EOs. The antimicrobial agents, generally used to avoid the increase of potential health risks due to bacterial infections, or the production of unpleasant odour, and to preserve food, are among these products. Numerous studies have demonstrated that plant extracts and EOs contain diverse bioactive components that can control or inhibit bacterial growth. Scientists and industry stakeholders have identified potential uses of nanotechnology in segments of the food industry, from agriculture to food processing, food packaging and nutrient supplements. Cosmetic products are suitable media for growth of checked microorganisms because of the materials in their compositions. Therefore, against the possibility of contamination, the addition of some preservatives in to the cosmetic products can prevent microbial growth.
