Finally, we contacted two experts of hospitals, told them about our project, and received some feedback. Doctor Fan, the
attending physician in Fuzhou Guoyi Tang Chinese Medicine Hospital, said that at
present, the diagnosis of the tumor through the puncture, biopsy production of pathological
sections and other means of the patient itself has some damage, and may even cause
the proliferation of tumor cells, aggravate the condition. And our project had application
prospects, especially for the detection of diabetes. And Doctor Yu, the deputy Chief
Physician in Chinese People 's Liberation Army 476th Hospital, said that it could
be considered to ask the patient to blow to detect whether the exhaled VOC contained
the associated disease odor, or to detect urine odor, but the interference was large.
Inspiration to our project:
• As the incipient disease emits very feeble VOCs, we designed the crispra-mediated
olfactory signal amplification pathway and successfully enhanced the sensitivity
of our biosensor to odor identification.
• For some interferential smell caused by the fungi, because our olfactory receptor
can only be combined with its specific odor, no matter what interferential odor exist,
our ismeller can specifically identify the corresponding odor.
• Because some tumor cells emit a variety of mixed odors, we intend to introduce
multiple olfactory receptors into one cell to achieve specific detection of multiple
odor to enhance the accuracy of cancer detection.
