Investigating the relationships between micro- to nano-scale hierarchical structures and biological functions / food properties via synchrotron X-ray imagingVisualization of spatially hierarchical structures from micro- to nanometer scales provides key insights for understanding the structural basis of biological functions in life and agricultural sciences. Properties of foods including texture, taste, and cooking/processing properties also arise from micro- to nanoscale structures. To investigate those structure-function relationships, we are developing imaging techniques using synchrotron X-rays and promoting their applications in life, agricultural and food sciences, and industries. I have particularly been developing the lensless nanoimaging techniques using coherent X-rays, called coherent diffraction imaging (CDI) and ptychography, under atmospheric and cryogenic conditions (Fig.1). In addition, I have developed machine-learning-based analysis technique for spectral images including X-ray absorption spectroscopic or small-angle X-ray scattering (SAXS) imaging to visualize heterogeneous distribution of chemical states or material phase transitions involving biological phenomena or food processing (Fig.2). We are also promoting the application of those techniques to various fields including soft materials, energy devices, etc.
