| 英文摘要 | carbon dots (c-dots) are a class of novel fluorescent nanomaterials, which have drawn great attention for their potential applications in bio-nanotechnology. multicolor c-dots have been synthesized by chemical nitric acid oxidation using the reproducible plant soot as raw material. tem analysis reveals that the prepared c-dots have an average size of 3.1 nm. the c-dots are well dispersed in aqueous solution and are strongly fluorescent under the irradiation of ultra-violet light. x-ray photoelectron spectroscopy characterization demonstrates that the o/c atomic ratio for c-dots change to from 0.207 to 0.436 due to the chemical oxidation process. the photo bleaching experiment reveals that the c-dots show excellent photostability as compared with the conventional organic dyes, fluorescein and rhodamine b. the fluorescence intensity of the c-dots did not change significantly in the ph range of 3-10. to further enhance the fluorescence quantum yield, the c-dots were surface modified with four types of passivation ligands, 4,7,10-trioxa-1,13-tridecanediamine (ttdda), poly-l-lysine (pll), cysteine and chitosan and the fluorescence quantum yields of the ttdda, pll, cysteine and chitosan passivated c-dots were improved 1.53-, 5.94-, 2.00- and 3.68-fold, respectively. fourier-transform infrared (ftir) spectra were employed to characterize the surface groups of the c-dots. the bio-application of the c-dots as fluorescent bio-probes was evaluated in cell imaging and ex vivo fish imaging, which suggests that the c-dots may have potential applications in biolabeling and bioimaging.
