    About 40 years have passed, since commercial surface analyses instruments for electron spectroscopy appeared, and these instruments are now widely used in production lines as well as research fields. Since 1982, many international research projects have been executed under VAMAS umbrella, and a lot of information has been obtained to improve the reliability of surface analyses. In 1991, ISO TC201 was established to achieve the standardization of surface chemical analyses, and 38 ISO standards have been published. In this paper, the research results on the improvement of the reliability of electron spectroscopy are introduced, and the ISO standards directly relating to the electron spectroscopy are explained.

    Probing the step-by-step bonding processes induced by the individual interactions in a molecular complex and their variation with the surrounding conditions is a key factor for enabling further advances in biophysics and chemistry and their applications. Here, we demonstrate a methodology that realizes the site-selective anatomy of molecular interactions at the single-molecule level. With the combination of cross-linkers and the atomic force microscopy (AFM) that we developed to enable a precise analysis by dynamic force spectroscopy (DFS), direct and bridged interactions at each reaction site in a typical ligand-receptor system, streptavidin-biotin complex, were clearly distinguished and individually analyzed for the first time, providing a greater understanding of step-by-step progress of the bonding process. This methodology will provide a foundation for further advances in biophysics and chemistry and their applications, such as designing and controlling the mechanism of chemical reactions between functional molecules.
