查询词典 red shift

The RRS intensity was enhanced obviously after the drugs and DNA reacting with each other, which indicated the formation of new products for the maximum peak appeared at around 375 nm with slight red shift. Then the Cu ion was added into the system to form a ternary system, and the RRS intensity was enhanced significantly, when the enhanced spectral value was directly proportional to the concentration of the DNA. Thus a highly sensitive method could be obtained for determining DNA and the detection limit of the experiment reached 9.7 ng/mL for the RFSV system.

两者反应形成结合产物后其RRS明显增强，并在375 nm左右出现最大散射峰，且有不同程度的红移和散射增强，说明两者结合成新的产物；加入Cu2＋离子后， Cu2＋与利福霉素抗生素及DNA形成三元复合物，此时将导致RRS进一步剧增，而且RRS光谱增强值与DNA浓度呈正比，因而可用于DNA测定具有较高的灵敏度，实验对ctDNA的检出限为9.7 ng/mL (RFSV-Cu2＋- ctDNA体系)。
