Bioconjugated quantum dots for in vivo molecular and cellular imaging
TL;DR: The synthesis and development of state-of-the-art QD probes and their use for molecular and cellular imaging are discussed and key issues for in vivo imaging and therapy, such as nanoparticle biodistribution, pharmacokinetics, and toxicology are examined.
Journal ArticleDOI
Nanotechnology Applications in Cancer
TL;DR: Developments in bioaffinity nanoparticle probes for molecular and cellular imaging, targeted nanoparticle drugs for cancer therapy, and integrated nanodevices for early cancer detection and screening raise exciting opportunities for personalized oncology in which genetic and protein biomarkers are used to diagnose and treat cancer based on the molecular profiles of individual patients.
Journal ArticleDOI
Multimodality Imaging Probes: Design and Challenges
TL;DR: This review provides an overview of the many strategies that have been applied to achieve multimodal functionality in a single probe unit and the caveat is that because the sensitivities of different imaging modalities can vary by 3 orders of magnitude, it may not be practical to simply add all functionalities to one molecule.

The cytotoxicity of cadmium-based quantum dots
Nan Chen,Yao He,Yuanyuan Su,Yuanyuan Su,Xiaoming Li,Qing Huang,Haifeng Wang,Xiangzhi Zhang,Renzhong Tai,Chunhai Fan +9 more
TL;DR: Recent progress on mechanistic studies of cytotoxicity of II-IV QDs are summarized to suggest that the cytot toxicity of CdTe QDs not only comes from the release of C d(2+) ions but also intracellular distribution of QD nanoparticles in cells and the associated nanoscale effects.
Journal ArticleDOI
Long-Term Exposure to CdTe Quantum Dots Causes Functional Impairments in Live Cells
TL;DR: For the various CdTe QD samples, there was no dose-dependent correlation between cell viability and intracellular [Cd2+], implying that their cytotoxicity cannot be attributed solely to the toxic effect of free Cd2+.

(CdSe)ZnS Core-Shell Quantum Dots - Synthesis and Characterization of a Size Series of Highly Luminescent Nanocrystallites
B. O. Dabbousi,Javier Rodríguez-Viejo,F. V. Mikulec,Jason Heine,Hedi Mattoussi,R. Ober,K. F. Jensen,‡,§ and,Moungi G. Bawendi +7 more
TL;DR: In this paper, a synthesis of highly luminescent (CdSe)ZnS composite quantum dots with CdSe cores ranging in diameter from 23 to 55 A was reported.
Journal ArticleDOI
Probing the Cytotoxicity Of Semiconductor Quantum Dots.
TL;DR: This work found that CdSe-core QDs were indeed acutely toxic under certain conditions and modulated by processing parameters during synthesis, exposure to ultraviolet light, and surface coatings, and suggests that cytotoxicity correlates with the liberation of free Cd2+ ions due to deterioration of the Cd Se lattice.
Journal ArticleDOI
The use of nanocrystals in biological detection
TL;DR: The emerging ability to control the patterns of matter on the nanometer length scale can be expected to lead to entirely new types of biological sensors capable of sensing at the single-molecule level in living cells, and capable of parallel integration for detection of multiple signals.

Formation of high-quality CdTe, CdSe, and CdS nanocrystals using CdO as precursor.

TL;DR: This paper proves that Cd(CH3)2 can be replaced by CdO and develops a one-pot synthesis which does not require separated preparation of cadmium complex and is reproducible and simple and thus can be readily scaled up for industrial production.
