BreathBiomicsTM Technology

Unlocking the full potential of human breath as a non-invasive source for disease diagnosis requires technologies that are both sensitive and robust. At Zeteo Tech, we’ve answered this call by developing a sampling system that excels where existing methods fall short. Our innovative approach captures biological molecules in human breath with unparalleled accuracy and reliability, delivering a powerful tool to complement traditional diagnostic methods. Whether for clinical research or everyday use, our sampling system is poised to revolutionize the way we detect and manage respiratory diseases.


Zeteo Tech has renovated the capturing mechanism and developed a sampling system, BreathBiomicsTM, for the comprehensive collection of biomolecules in human breath. 


Highlights of BreathBiomicsTM

  • Comprehensive capture of biomolecules
  • Easy to use
  • Small footprint
  • Suitable for use in clinical and point-of-care settings
  • Compatible with conventional analytical methods

A novel mechanism to capture biomolecules in human breath

BreathBiomicsTM sampling system offers a novel capture mechanism through advanced surface chemistry, providing a comprehensive and efficient collection of non-volatile organic compounds present in human breath. Our system is composed of chemically modified functional groups that display high affinity for a diverse range of biomolecules, including lipids, metabolites, and proteins, allowing for a thorough and accurate assessment of respiratory health. The molecular interactions utilized in our capture mechanism enable the collection of biomolecules contained within submicron particles, overcoming a critical limitation of existing collection technologies. Furthermore, our system’s functional groups can be tailored for targeted collection, such as those with specific affinity to SARS-CoV-2 biomarkers, providing unprecedented flexibility in biomarker identification and diagnosis.

A sampling system for easy use in clinical settings

BreathBiomicsTM sampling system provides unparalleled versatility in its integration into a variety of respiratory devices including facial masks, mouthpieces, mechanical ventilators, oxygen masks, incubators, and tracheostomy tubes. Its quiet operation, with noise levels below 45 dB (comparable to the hum of a home refrigerator), makes it ideally suited for deployment in clinical settings, ranging from primary care sites to emergency rooms, operating rooms, and intensive care units.

Collaborate with us

Zeteo Tech is at the forefront of harnessing advanced technology to unlock the full potential of human breath as a diagnostic tool. With our innovative BreathBiomicsTM sampling system, we aim to revolutionize disease diagnosis by extracting invaluable biological information from human breath.
