“…And as shown in Fig. 2, the disappearance of CdTe diffraction peaks and the observation of CdS diffraction peaks suggested that the as-prepared CdTe/CdS QDs probes had a core-shell structure rather than a CdTexS 1-x alloyed structure (Dong et al 2009), and similar XRD results had been reported in other literatures (Bailey and Nie 2003;Gaponik et al 2002;Haobo Bao et al 2004;He et al 2006;Pan et al 2005;Zhong et al 2003). It was found that the formed core-shell structure made probe A show a red-shift in its adsorption peak, (Mekis et al 2003;Pan et al 2005), but for probes B and C, due to the inhibition on the growth of CdTe core and the CdS shell caused by the long carbon chain, they show a blue-shift in the adsorption peak.…”

A series of quantum dots (QDs) fluorescent probes for the in situ identification of Microthrix parvicella (M. parvicella) in bulking sludge were designed and prepared. In the preparation of CdTe/CdS QDs, the 11-mercaptoundecanoic acid (11-acid) and 16-mercaptohexadecanoic acid (16-acid) were used as the stabilizer. The prepared QDs probes were characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and transmission electron microscopy (TEM), and the results showed that the CdTe/CdS QDs formed a core-shell structure and the long carbon chain was successfully grafted onto its surface. And the three QDs probes had different crystallinity and particle size, which was due to the inhibition effect of long carbon chain. The optical properties test results showed that although the formed core-shell structure and long carbon chain affected the fluorescent intensity, adsorption, and emission spectra of the QDs probes, the probes B and C had a large stokes-shift of 82 and 101 nm, which was a benefit for their fluorescent labeling property. In the fluorescent identification of M. parvicella, the probes B and C effectively adsorbed onto the surface of M. parvicella through a hydrophobic bond, and then identified M. parvicella by their unique fluorescence. In addition, it was found that a better hydrophobic property resulted in better identification efficiency.

“…For example, Weng et al synthesized CdTe QDs conjugated with either plant lectin or antibody anti-von Willebrand factors as biological labels for targeted cancer cell imaging [72]. Dong et al reported the preparation of bioconjugated CdTe QDs for labeling prostate cancer cells [73]. Li et al demonstrated the synthesis of PEGylated CdTe QDs for imaging human tongue cancer cells without observing any damage to the cells [74].…”

Over the past few years, CdTe quantum dots have been demonstrated as powerful probes for biophotonics applications. The aqueous phase synthesis technique remains the best approach to make high quality CdTe QDs in a single‐pot process. CdTe QDs prepared directly in the aqueous phase can have quantum yield as high as 80%. In addition, the surface of CdTe QDs prepared using the aqueous phase technique is functionalized with reactive groups that enable them to be directly conjugated with specific ligands for targeted delivery and sensing. In this contribution, we review recent progress in fabricating aqueous CdTe QDs and exploiting their optical properties in novel approaches to biomedical imaging and sensing applications.

“…Semiconductor nanocrystals, also named quantum dots (Qdots), have been widely explored as biomedical labeling reagents since 1998 [1][2][3][4][5][6][7]. The fluorescence of Q-dots is intrinsic, bright, and prolonged, and surpasses the sensitivity and resolution capability of organic dyes and proteins.…”
