[交流] 试纸条做法求助 已有1人参与

Figure 7A shows the identical test paper under natural light, and no obvious change could be observed. However, the fluorescence of the Zn-BTEC test paper was immediately turned on in varying brightness levels upon addition of different concentrations of CTC, showing bright green spots against a dark-blue fluorescence background, which can be clearly seen under a 365 nm UV illumination (Figure 7B,C). Such fluorescence color changes on the test paper roughly indicate the concentration range for CTC visual detection. 请问科研朋友们，1.这种试纸条是用什么做的还是买的先成的？2. 这种是如何拍摄的？如何做到三行图片之间是黑色的，这是用了特殊的板子了嘛？ 麻烦诸位给点好的意见，谢谢 1626057110(1).jpg
