Design Considerations for Tumour-Targetting Nanoparticles

One of the challenges of using nanoparticles for imaging tumors during surgery is that there needs to be a tradeoff between the number of nanoparticles that target a tumor and the rapid clearance of any unbound nanoparti...

MRI Contrast Agent and Nanodiamond Dramatically Enhances Signal Intensity

A Northwestern University study shows that coupling a widely used magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast. &quo...

Enhanced Photoreception with Nanochip

Rod cells, or rods, are photoreceptor cells in the retina of the eye that can function in less intense light than can the other type of photoreceptor, cone cells. Named for their cylindrical shape, rods are concentrated ...

Nanotechnology Treatment Boosts Efficiency of Organic Solar Cells

A German team of scientists has developed a technique to treat nanoparticle surfaces. This treatment boosts the efficiency of organic solar cells. Presented in the journal Applied Physics Letters, the work shows how 2% efficiency was obtained by using so-called quantum dots made up of cadmium selenide.

Modeling of Nanowire Transistors Shows that Quantum Effects Must be Taken into Account in Their Design

Silicon nanowires are a leading candidate for use in next-generation transistors because they allow for high densities and speeds, as well as low operating power. Numerical modeling is a key part of nanowire transistor d...
