CdSe量子点

Using oleic acid as a stabilizer and paraffin as a reducing agent, CdSe quantum dots with uniform size were synthesized via the organic phase method, and the synthesized quantum dots were transferred to the aqueous phase through thioglycolic acid. The interaction patterns between CdSe quantum dots and several proteins (enzymes) with different structures were investigated. The study found that after interacting with bovine serum albumin and chymotrypsin, the fluorescence intensity of quantum dots modified with thioglycolic acid significantly increased. However, copper/zinc-superoxide dismutase had a significant quenching effect on the fluorescence of quantum dots, and the effect of bovine hemoglobin on quantum dots was that the fluorescence intensity first increased and then decreased with time, reflecting the synergistic effect of general proteins enhancing fluorescence and some metal ions quenching fluorescence山东pg电子娱乐游戏app 微生物供应各种相关服务:CdSe量子点InP量子点ZnSe量子点PbS量子点碳量子点水溶解性量子点量子点荧光微球,包埋CdSe/ZnS量子点的二氧化的硅微球以内原创文章介绍源头四种期刊杂志或论文参考文献,要是有版权侵权请连续我门删掉!
