Study on the physical properties of the ionic liquids and their applications for bio samples

用扫描电子显微镜观察了正常的疏水碳纳米管和经疏水和亲水离子液体处理后的亲水碳纳米管。在扫描电子显微镜观察中，容易观察到疏水样品和疏水液体、亲水样品和亲水液体组合的样品，而其他选择的样品和液体之间的亲和力较差的样品则被电子束充电。这些结果表明，对样品表面具有良好亲和力的离子液体可以在样品表面铺展。还尝试了用离子液体对红细胞进行预处理的观察。扫描电子显微镜下观察到的细胞没有破坏和变形，只需用离子液体进行简单的预处理。

Normal hydrophobic carbon nanotubes and hydrophilic ones which were pretreated hydrophobic and hydrophilic ionic liquids were observed with SEM. The samples with the combinations of hydrophobic samples and hydrophobic liquids, and, hydrophilic samples and hydrophilic liquids were easily observed, while samples by other choices for bad affinity between samples and liquids were charged up by electron beam during SEM observations. These results mean that ionic liquids which have good affinities for the samples surfaces can spread on the surfaces.The observations of red blood cells with pretreatment with ionic liquids were also tried. It is succeeded that the cells were observed by SEM without destructions and deformations, only with simple pretreatment by ionic liquids.
