Extensive Nobel Prize–recognized research has shown that cells and microorganisms
within the human body generate gaseous signaling molecules, such as nitric oxide (NO),
which are essential regulators of physiological and pathological processes.Leveraging this scientific insight,
Sunvou has pioneered breath-based detection technologies for NO and other gaseous biomarkers,
leading the emergence of a new sector in medical and healthcare diagnostics.
