| 摘 要： | 使用溶胶-凝胶法将常用的指纹显现剂DFO制成凝胶,根据其溶剂挥发慢、扩散难以及立面不流淌的特性,将其试用于打印纸、人民币等渗透性的样品,效果与溶液法相当;在抽屉、门等非渗透性垂直表面,凝胶法的指纹显现效果明显优于传统DFO溶液。

| Abstract: | The sol-gel method was used to prepare gel-type DFO fingerprint reagent. On trial, the new DFO fingerprint reagent was used on permeable sample such as copy paper, filter paper and paper money, its performance is close to common DFO solution. On the basis of its slow solvent volatilization, low diffusion and no flow on impermeable vertical faces, the performance of gel-type DFO is obviously superior to common DFO solution. |
