    Abstract: The present invention relates to a method for evaluating a SERS sensor substrate, comprising the steps of: a) measuring, through a dark-field microscope, the color of nanoparticles positioned on the SERS sensor substrate; b) converting the measured color into a distance between the nanoparticles; c) acquiring the Raman signal intensity of the SERS sensor substrate; d) acquiring the standard Raman signal intensity of a standard SERS sensor substrate including the nanoparticles having the distance that is the same as the converted distance; and e) comparing the Raman signal intensity and the standard Raman signal intensity.

    Abstract: An object of the application is to provide a head-integrated for an atomic force microscope capable of realizing minimization of a weight and a volume and improvement of structural stability by optimizing a head structure of the atomic force microscope. Another object of the application is to provide a head-integrated atomic force microscope capable of being utilized for imaging a large-area sample by enabling high-rate head scan due to dynamic characteristics improved by mounting the integrated-head described above. Still another object of the application is to provide a composite microscope including a head-integrated atomic force microscope, capable of performing high-rate position search and imaging and performing precise observation of a three-dimensional shape up to an atomic image level in a region of interest by combining the head-integrated atomic force microscope having the improved dynamic characteristics as described above and an electron microscope or an optical microscope with each other.
