Essential oils are containing phytochemical components derived from plants. Their antimicrobial properties enable to disinfect or inhibit the growth of microorganisms, which may be harmful to plants or humans. The aim of our research is to develop a formula using antimicrobial capsules and essential oils. The research is to examine phytochemical-based antimicrobial formulation into coating materials for sustained surface disinfection, controlled-release and anti-adhesion properties. An understanding of the inhibition and inactivation mechanisms of these phytochemicals is essential for their optimal formulation. Target microorganisms will include Gram+ and Gram- bacteria, and fungal spores and tests will be carried out under conditions that simulate practical use. Finally, the coating will be reformulated to optimize bactericidal efficiency and durability by examining the impact factor of chemicals used. Several experiments were launched to optimize the formula, for example, the amount of each component used was reduced to minimize the usage and maximize bactericidal efficacy.  Release rate test and long term bactericidal test were launched on glass medium. It shows that the coating can remain over 90% bactericidal performance in a month.
