混合法制备的双锥角型光纤探针的应用

Application of double-tapered optical fiber probe fabricated by hybrid method

  • 摘要: 为了提高双锥角型光纤探针的捕获效率,采用静态化学腐蚀法制备1次锥角,研磨法制备2次锥角,然后使用基于双锥角型光纤探针的单光纤光镊系统对酵母菌细胞进行捕获实验; 并采用界面层腐蚀法制备出了参数相近的双锥角型光纤探针,分别测量了两种不同方法制备的光纤探针对酵母菌细胞的捕获力大小。结果表明,混合法制备的双锥角型光纤探针具有更好的表面光滑度和对称性,其捕获效率比界面层腐蚀法制备的双锥角型光纤探针提高了20%。该研究对混合法制备双锥角型光纤探针是有帮助的。

     

    Abstract: In order to improve the trapping efficiency of the double-tapered optical fiber probe(DOFP), the first taper angle was fabricated by the static chemical etching method, and then the second taper angle was fabricated by the polishing method. Trapping experiment of a yeast cell was completed using a single optical fiber tweezer system based on DOFP. In addition, a DOFP with similar parameters was fabricated by interfacial layer etching method. The trapping force of two DOFPs fabricated by two different methods on the yeast cell was measured. The results show that, DOFP fabricated by the hybrid method has better surface smoothness and symmetry. Its trapping efficiency is 20% higher than that of DOFP fabricated by the interfacial layer etching method. This study is helpful for the fabrication of double-tapered optical fiber probes using the hybrid method.
