Tokyo Medical/ Dental Univ: Development of gas imaging (sniffing camera): Diabetes, cancer / early screening
Tokyo Medical Dental University: Gas Imaging (Sniffing Camera)
On December 25, 2019, we announced that we have developed a “gas imaging device (sniffing camera)”.
Detects extremely small amounts of blood-derived volatile components emitted from the skin.
Also, image the concentration distribution in real time.
Gas Imaging (Sniffing Camera): Equipment Specifications
Gas loading method that mimics the release of transdermal gas,
Accurate gas imaging / fitting on body surface,
Newly developed drawing device (two-dimensional true arc).
Gas imaging (sniffing camera): Experimental results
Using this device, “skin gas released from test subjects after ingesting alcoholic beverages” was tested.
Succeeded in real-time imaging of “the distribution of ethanol and acetaldehyde concentration in skin gas”.
In the experiment, the target sites were “palms, fingers, soles, and ears with different sweat gland densities and numbers of epidermal layers.”
“Sweat glands and thin epidermis / opening of the ear canal are suitable for measurement of blood volatiles.”
Ethanol / acetaldehyde: alcohol test
Biofluorescence method using “nicotine-dependent alcohol / dehydrase catalytic reaction” is used.
By changing the type of enzyme, other skin gases can be detected.
Equipment developed this time
Gas components without smell
Even with trace components,
The concentration distribution information can be displayed quantitatively.
The research group
Non-invasive skin gas measurement
Diseases such as diabetes and some cancers,
We aim to develop an early screening method.
