Nowadays, electron microscopy is a widespread method used in many biological branches like medicine, physical science, mikrobiology or material technology. Scanning electron microscope is a type of an electron microscope that shows the sample surface by scanning it with a high-energy beam of electrons in a raster scan pattern. The signal of electrons reveals information about the sample such as morphology, chemical composition and structure and materials. Gold nanoparticles are widely used as a marker for immunolabeling in these days. The main point of this research was to find other nanoparticles, which can be used for multiple immunolabeling. The main task of this study is to conjugate these particles with atibodies, to use them for immunolocalisation on the convenient biological sample and to observe it in FESEM JEOL JSM-7401F.
