Quantum Dots within Thermoelectric Material Increase Heat-to-Energy Conversion

High-performance thermoelectric materials that convert waste heat to electricity could one day be a source of more sustainable power. But they need to be a lot more efficient before they could be effective on a broad scale in places like power plants or military bases, researchers say.

Water-Loving, Jelly-Like Materials may Help Test Biological Effects of Nanoparticles

A class of water-loving, jelly-like materials with uses ranges ranging from the mundane, such as superabsorbent diaper liners, to the sophisticated, such as soft contact lenses, could be tapped for a new line of serious work: testing the biological effects of nanoparticles now being eyed for a large variety of uses.

Nanotechnology Enables Safe Delivery of Reformulated TNF-alpha to Cancer Cells

The protein tumor necrosis factor-alpha (TNF-alpha) is a powerful weapon in the arsenal to control cancer. Unfortunately, as is the case with many potent cancer therapies, the use of TNF-alpha as an anti-cancer therapy has been severely limited. “It was so toxic that it caused death,” and researchers gave up on it, explains Scott McNeil, director of the Nanotechnology Characterization Lab at the Frederick National Laboratory for Cancer Research.

Quantum Dots Embedded Within Nanowires Boost Efficiency of Photovoltaic Cells

Using exotic particles called quantum dots as the basis for a photovoltaic cell is not a new idea, but attempts to make such devices have not yet achieved sufficiently high efficiency in converting sunlight to power. A new wrinkle added by a team of researchers at MIT — embedding the quantum dots within a forest of nanowires — promises to provide a significant boost.

Scientists Employ Quantum Dots for Single-Cell Analysis and Clinical Diagnosis

Better diagnosis and treatment of cancer could hinge on the ability to better understand a single cell at its molecular level. New research offers a more comprehensive way of analyzing one cell’s unique behavior, using an array of colors to show patterns that could indicate why a cell will or won’t become cancerous.
