The concentration of such particulate matter and chemical residual will highest immediately after cleaning, and will decrease over time depending upon levels of contaminants, air exchange rate, and other sources of chemical residual. [5] Of most concern are the family of chemicals called VOCs such as formaldehyde, toluene, and limonene. [7]
Antimicrobial surfaces are functionalized in a variety of different processes. A coating may be applied to a surface that has a chemical compound that is toxic to microorganisms. In the alternative, it is possible to functionalize a surface by adsorbing a polymer or polypeptide and/or by changing its micro and nanostructure. [4]
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. [1] Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life.

[2] A pharmaceutical drug , also called a medication or medicine, is a chemical substance used to treat , cure, prevent , or diagnose a disease or to promote well-being . [ 3 ]
Bioactive agents are substances that can influence an organism, tissue or cell. Examples include enzymes, drugs, vitamins, phytochemicals, and bioactive compounds. Bioactive agents can be incorporated into polymers, [1] [2] which has applications in drug delivery and commercial production of household goods and biomedical devices. [2]
