This letter proposes the use of choline-like hydrophilic ionic liquids (ILs) to visualize hydrous samples (e.g., seaweed and other biological or food samples) for scanning electron microscopy (SEM) observation. Some of the water in the samples was successfully replaced with these ILs, which penetrated the cell membranes. The treated samples did not contract much even after drying. The ILs' ionic conductivity decreased the charging of sample surfaces, and good SEM images were obtained.
这封信提出使用胆碱类似的亲水性离子液体 (ILs) 来可视化含水样品（例如，海藻和其他生物或食品样品），以便进行扫描电子显微镜 (SEM) 观察。这些 ILs 成功地替代了部分样品中的水分，并渗透到细胞膜中。即使在干燥后，处理过的样品也没有明显收缩。ILs 的离子导电性降低了样品表面的充电，从而获得了良好的 SEM 图像。
