Various volatile substances associated with disorders are released from human bodies. In order to utilize them as biomarkers of related diseases, a highly sensitive and highly selective method for gas measurement is strongly requested. Biochemical gas sensors (bio-sniffer) that use biochemical reaction of enzyme have been developed and tested in biomedical applications. Owing to the specific activity of enzyme, the bio-sniffer provides high-sensitivity and high-selectivity with a relatively simplified system. This paper reports on the current status of bio-sniffer development and applications to medical and healthcare fields.
