A new field of Analytical Chemistry, Bio-Analytical Chemistry, is proposed. It would treat the analysis of biomolecules related to the maintenance of homeostasis in living mammals, the analysis of biomolecules or chemicals of unknown as well as known physiological roles and also would include the development of methods to search into and clarify the mysteries in nature. Some examples of our studies performed in the line of this field are presented. The proposal is made in order to stimulate more young people to participate in and be involved in the promotion of Analytical Chemistry.
