Using lasers and nanoparticles, scientists at Rice University have discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make "nanobubbles" by zapping gold nanoparticles inside cells. In tests on cancer cells, they found they could tune the lasers to create either small, bright bubbles that were visible but harmless or large bubbles that burst the cells.
Nanotools enable imaging, quantification, fabrication, and modeling of a substance/material at the nano level. Several institutions and enterprises including government, private investors, corporate, and academic organizations are funding research-based operations, to develop applications incorporating nano-scale technologies. Nanotools market in the United States is witnessing growth in intellectual property litigations owing to patent infringements. Advances in instrumentation technologies are increasingly impacting the future of nanotechnology. Instruments encompass "nanotools" that aid in observing, measuring, and engineering nanostructures.
Stephan Link wants to understand how nanomaterials align, and his lab's latest work is a step in the right direction.
A mystical glow emanates from the display case. A white light appears out of nowhere. And a light source is invisible – at least at first glance.
Scientists at the Department of Microsystems Engineering (IMTEK) and the Freiburg Materials Research Center (FMF) have succeeded in developing a method for treating the surface of nanoparticles which greatly improves the efficiency of organic solar cells. The researchers were able to attain an efficiency of 2 percent by using so-called quantum dots composed of cadmium selenide.
With new, advanced equipment, scientists at Risø DTU have shown that materials to produce micro-and nanocomponents react very differently depending on whether crystals are large or small. This research creates important knowledge that can be used to develop technologies aimed at the nanoproduction of micro-electro-mechanical systems such as digital microphones in mobile phones, miniature pressure sensors in water pumps and acceleration sensors in airbags.
QD Vision, Inc., developer of Quantum Light™ nanotechnology-based products for solid state lighting and displays, announced today that DTE Energy Ventures has invested $3 million in the company. The funding will support QD Vision’s market expansion of quantum dot-based nanomaterials that enable major efficiency gains in high-quality solid-state lighting and flat panel displays.
The industrial and research role of sensors and associated instrumentation technologies has never been greater. However, industry demands are increasingly stringent and sophisticated, requiring innovative development of sensor technology. Nanotechnology can drive the advances needed to achieve these market demands. Novel tools, techniques and materials mean that the next generation of sensors will be smaller, have increased sensitivity, require specific functions, and consume less power.
