| 1 | Immune fluorescence test strips based on quantum dots for rapid and quantitative detection of carcino-embryonic antigen显示文摘At present,many researchers focused on the point-of-care testing(POCT),a method of disease markers detection without large-scale instruments and specialized persons.However,most POCT diagnostic methods were suffered from poor detection sensitivity or inefficiency in quantitative detection.Herein,we developed a newly QD-immune fluorescence test strips(QD-IFTS) based on quantum dots(QDs) as the fluorescence nanocarrier to prepare the immune fluorescence probes in the classical immunochromatography detection system for sensing carcino-embryonic antigen(CEA),a kind of glycoprotein produced by intestinal tissue and a broad spectrum of tumor marker for cancer diagnosis.And we designed a homemade strips fluorescence reader for detection of fluorescence intensity of QDs on the QD-IFTS.Under the optimized reaction conditions,chromatographic time of the newly QD-IFTS was only25 min,sample volume of the newly QD-IFTS was only 40 m L and the LOD of the newly QD-IFTS was 0.72 ng/m L.In addition,the efficiency and robustness of the newly QD-IFTS were confirmed by successfully application in 300 clinical serum samples,and the results revealed great potential in clinical POCT of other biomarkers. | Yudong Wu Weipan Peng Qian Zhao Jiafang Piao Bo Zhang Xiaoli Wu Hanjie Wang Zhihong Shi Xiaoqun Gong Jin Chang | 2017 | Chinese Chemical Letters2017，28，9： | 3 |
| 2 | Single-stranded RNA as primers of terminal deoxynucleotidyl transferase for template-independent DNA polymerization显示文摘Terminal deoxynucleotidyl transferase(Td T) has been characterized as template-independent polymerase using single-stranded DNA(ss DNA) as primers to generate random oligonucleotides. However, the extension performance of Td T to single-stranded RNA(ss RNA) is vague. By systematically comparing and contrasting the performance of Td T-catalyzed ss DNA and ss RNA extension, it is indicated that the catalytic efficiency of ss RNA as primers was about 3 times lower than ss DNA as primers. Collectively, it is believed that understanding the catalytic performance of Td T will help to design the strategy to synthesize chimeric DNA on 3-OH of ss RNA, which becomes invaluable. | Houyu Han Jingyu Cui Dianming Zhou Deping Hua Weipan Peng Mengyao Lin Yating Zhang Fangya Li Xiaoqun Gong Jianyu Zhang | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
