    - Successful development of technology that reproduce sense of smell that can recognize various smells

    - Dr. Oh Seok Kwon, Dr. Hyun-Seok Song of KBSI, Dr. Seon-Joo Park of Seoul National University and Dr. Jeong-Sik Chang conducted the research jointly.


    Korea Research Institute of Bioscience & Biotechnology (hereinafter referred to as KRIBB, President Tae-Kwang Oh) and Korea Basic Science Institute (hereinafter referred to as KBSI, President Kwang-Hwa, Jeong) announced that they successfully developed the technology for high-performance bionano-electronic nose that can recognize smells through joint research with Seoul National University for the first time in the world.


    Sense of smell is the least known area among senses of human body due to its complexity and in particular, sense of smell has very complex mechanism as it is composed of neural signals generated by many neural cells of olfaction.


    In particular, olfactory receptor*, which is known to be hard to be represented in different types of cells as it is composed of membrane protein represented in cell membrane having very complex structure, is successfully represented in colon bacterium system in large scale and separated and refined to increase the effectiveness of electronic nose.


    The result of the research was published in online edition of Nano Letters, IF : 13.592, which is world’s renowned journal in nano science sector (thesis title: An Ultrasensitive, Selective, Multiplexed Superbioelectronic Nose That Mimics the Human Sense of Smell) on Sept. 24.


    The research outcome can be utilized in various fields including detection of smells that harm human body like toxic gases, recognition of volatile organic compounds included in person’s breath and urine to identify cancer indicators, detection of food and scent and early detection of drug and biochemical weapons as the technology can replace the nose of human. It is expected that the technology can be applied to advanced science and technology related to human life in the future including TV technology that make viewers smell through coding of human’s sense of smell.




    Dr. Oh Seok Kwon of KRIBB said “the research is meaningful in that bio-nano electronic nose, that is very similar to human nose and highly sensitive, is developed for the first time in the world by replacing nano material (carbon nano tube and conductive high molecule) that has been used for existing bio electronic nose system that can recognize only single molecule smell with single graphene with micro pattern that can recognize multiple molecule smell with high sensitivity like actual human nose”.


    Dr. Hyun-Seok Song of KBSI announced that “human recognize smell by combining olfactory signal created by various olfactory neural cells and this research is meaningful in that the technology that is closer to human’s olfactory system is developed and I think that we take a step closer to standardization of coding olfactory system of human, which cannot be reproduced with the current technology”.


    Dr. Oh Seok Kown of KRIBB and Dr Seon-Joo Park of Seoul National University, who conducted this research jointly were student of the professor Seong-Sik Chang of Seoul National University who is an expert of nano structure manufacturing area and Dr. Hyun-Seok Song of KBSI learned from professor Tae-Hyun Park of Seoul National University who is an expert of bio sensor and performed high-performance artificial sensor development and research since he was a student of professor Park.
