Research Abstract |
In this study, we have used ionic liquids as the SEM visualizing reagent of non-conductive nanomaterials and bio-related samples including cells and construct an optimized pre-treatment method for SEM observation. Ionic liquids are organic salts which are in liquid at room temperature and do not evaporate even in a vacuum conditions. Therefore, they should be a suitable material for SEM visualization. We have been able to establish the processes to visualize non-conductive nanomaterials during this research period. For bio-related samples, including cells, we applied choline-type structured ionic liquids as the visualizing agents. The samples were dispersed in the ionic liquids and put on a membrane filter. The dispersion was filtered gently under reduced pressure by using a syringe and excess ionic liquids were removed. Using this process, red blood cells could be observed by SEM without any deformation.
