THz interaction with biomolecules
Gun-Sik Park, PhD
Seoul National University
Abstract: Historically the discovery of new electromagnetic wave spectrum always has lead to the great invention of biomedical imaging systems for the diseases diagnostics and treatment. All the great discoveries such as NMR, CT and PET utilize the electromagnetic waves of RF, X-ray and gamma-ray, respectively. It is not surprising to see that such a great contribution to the mankind was awarded as Nobel Prize. These biomedical imaging systems revolutionized the modern society and continues to be developed in much more improved resolution and sensitivity providing us with better health care. The wavelength and the energy of each electromagnetic wave spectrum is the basis for its uniqueness in its interaction with matters. The only frequency spectrum which is not explored yet, is remained for us to be explored as a “THz gap” is THz wave classified as 0.3-3THz or 0.1-10THz. Now looking back to the history, it is likely that THz wave also inevitably will create a novel biomedical systems. Nowadays growing number of researches are being carried out in the areas of THz biomedical imaging, THz sensing, and various THz diagnostics all over the world. One of the great THz uniqueness is to identify the inter-molecular movements in matters.
Which will provide THz wave with the feasibility of novel modality with “finger-print” in biomedical systems as a spectral imaging. However, a big challenge for THz wave is its attenuation and consequently less penetration depth due to water in tissues. Water is a “friend or an enemy” in THz biomedical systems? In the Center for THz-Bio Application Systems, major efforts on realizing the THz spectral imaging, understanding the water dynamics in biomolecules and its role in biomedical processes and THz effects are being investigated.
The presentation will be focused mainly on the introductory THz-Bio interactions.
