several kinds of polymer and inorganic transparent pigment as raw materials.The manufacturing technique and security principle of spectrum-fingerprint fiber were discussed by means of scanning electron microscopy(SEM),X-ray diffraction(XRD) and Fluorescence spectrophotometer.The results showed that the melt...
Use a 3nh spectrophotometer or colorimeter to measure the color of the sample under UV and UV-free light sources, and compare the data to separate the fluorescence effect. The emission spectrum characteristics of the Optical Brightening Agents (420-480 nm) will form a peak in the result, and...

25 to 99°C while recording extrinsic fluorescence of the solvatochromic dye 8-anilino-1-naphthalene sulfonate (ANS) or Sypro Orange and determining the protein melting temperatures at each compound concentration by fitting the melting curves to a two-state model of the protein unfolding (28,29)....
Excitation light was provided at a wavelength of 488 nm (for CF) and 559 nm (for PI) by argon-ion and helium-neon lasers, respectively. The beam splitter DM 405/488/559/635 was used. Fluorescence emission was collected in the range of 497–558 nm (CF) or 579–679 nm (PI). A ...
