Nono & Bio Analysis Technology

Task 5 investigates the imaging technology and dynamics at the hetero-interface of nano-scale bio molecules using femto-second x-ray. Especially, quantum optics includes the study of coherent properties of the photons and their applications. Unlike in the classical optics, using coherent properties of the photons enables observation of very fast interaction between light and matter and the detailed structure inside the matter. It also allows close examination of various ultra-fast phenomena by the optical fields in the matter compared to the traditional slower electronic phenomena. Task 5 focuses on the measurement technology with two main topics.

1)Characterization of the interface in nano-bio-device
