Renal clearance of quantum dots
This study has precisely defined the requirements for renal filtration and urinary excretion of inorganic, metal-containing nanoparticles and provides a foundation for the design and development of biologically targeted nanoparticles for biomedical applications.
Synthesis and characterization of nearly monodisperse CdE (E = sulfur, selenium, tellurium) semiconductor nanocrystallites
A simple route to the production of high-quality CdE (E=S, Se, Te) semiconductor nanocrystallites is presented. Crystallites from ∼12 A to ∼115 A in diameter with consistent crystal structure,…
(CdSe)ZnS Core-Shell Quantum Dots - Synthesis and Characterization of a Size Series of Highly Luminescent Nanocrystallites
We report a synthesis of highly luminescent (CdSe)ZnS composite quantum dots with CdSe cores ranging in diameter from 23 to 55 A. The narrow photoluminescence (fwhm ≤ 40 nm) from these composite dots…

A three-dimensional range camera able to look around a corner using diffusely reflected light that achieves sub-millimetre depth precision and centimetre lateral precision over 40 cm×40cm×40 cm of hidden space is demonstrated.
Near-infrared fluorescent type II quantum dots for sentinel lymph node mapping
It is demonstrated that the fluorescence emission of type II quantum dots can be tuned into the near infrared while preserving absorption cross-section, and that a polydentate phosphine coating renders them soluble, disperse and stable in serum.
Synthesis and characterization of nearly monodisperse CdE (E = S, Se, Te) semiconductor nanocrystallites
A simple route to the production of high-quality CdE (E = S, Se, Te) semiconductor nanocrystallites is presented. Crystallites from ∼ 12 A to ∼ 115 A in diameter with consistent crystal structure,…
Synthesis and Characterization of Monodisperse Nanocrystals and Close-Packed Nanocrystal Assemblies
▪ Abstract Solution phase syntheses and size-selective separation methods to prepare semiconductor and metal nanocrystals, tunable in size from ∼1 to 20 nm and monodisperse to ≤5%, are presented.…
Angiotensin inhibition enhances drug delivery and potentiates chemotherapy by decompressing tumour blood vessels
Losartan reduces solid stress in tumours resulting in increased vascular perfusion, thereby potentiating chemotherapy and reducing hypoxia in breast and pancreatic cancer models, suggesting that angiotensin inhibitors —inexpensive drugs with decades of safe use — could be rapidly repurposed as cancer therapeutics.
Fluorescence intermittency in single cadmium selenide nanocrystals
SEMICONDUCTOR nanocrystals offer the opportunity to study the evolution of bulk materials properties as the size of a system increases from the molecular scale1,2. In addition, their strongly…
Emergence of colloidal quantum-dot light-emitting technologies
This Review article summarizes the key advantages of using quantum dots (QDs) as luminophores in light-emitting devices (LEDs) and outlines the operating mechanisms of four types of QD-LED. The key…
