Thai researchers claim to have developed an electronic nose,which can enable the local food industry to standardize smell.
To develop the new device known as NanoNos,the researchers at NANOTEC,King Mongkut's Institute of Technology Ladkrabang,and Mahidol University,utilized the knowledge in areas related to surface analysis,nanaocoating,and existing sensor technology.
The new bio-mimetic device is based on series of gas sensors,which provide a quasi-quantitative measure of the signature of smell.The device enables the analysis of volatile compounds generated by liquid,gaseous or solid samples.
It maps each fingerprint to known chemical substance patterns in a data library,following which,it either matches the fingerprint,or records the sample as a new pattern,reported Nanotech-now.com.
According to researchers,through this research,various NanoNose applications can be developed for agriculture,food science,health and environmental monitoring.
The device has been used to distinguish different types of smell,including fine scents such as perfume,alcoholic beverages,and coffee aroma.
