New nanolaser key to future optical computers and technologies
Purdue University August 17th, 2009 Demonstration of SPASER-based Nanolaser M. A. Noginov1, G. Zhu1, A. M. Belgrave1, R. Bakker2, V. M. Shalaev2, E. E. Narimanov2, S. Stout3, E. Herz3, T. Suteewong3, U. Wiesner3 1 Center for Materials Research, Norfolk State University; 2 School of Electrical & Computer Engineering and Birck Nanotechnology Center, Purdue University; 4 Materials Science and Engineering Department, Cornell University One of the most rapidly growing areas of physics and nanotechnology focuses on plasmonic effects on the nanometre scale, with possible applications ranging from sensing and biomedicine to imaging and information technology. However, the full development of nanoplasmonics is hindered by the lack of devices that can generate coherent plasmonic fields. It has been proposed that in the same way as a laser generates stimulated emission of coherent photons, a "spaser" could generate stimulated emission of surface plasmons (oscillations of free electrons in metallic nanostructures) in resonating metallic nanostructures adjacent to a gain medium. But attempts to realize a spaser face the challenge of absorption loss in metal, which is particularly strong at optical frequencies. The suggestion to compensate loss by optical gain in localized and propagating surface plasmons has been implemented recently and even allowed the amplification of propagating surface plasmons in open paths. Still, these experiments and the reported enhancement of the stimulated emission of dye molecules in the presence of metallic nanoparticles lack the feedback mechanism present in a spaser. Here we show that 44-nm-diameter nanoparticles with a gold core and dye-doped silica shell allow us to completely overcome the loss of localized surface plasmons by gain and realize a spaser. And, in accord with the notion that only surface plasmon resonances are capable of squeezing optical frequency oscillations into a nanoscopic cavity to enable a true nanolaser, we show that outcoupling of surface plasmon oscillations to photonic modes at a wavelength of 531 nm makes our system the smallest nanolaser reported to date - and to our knowledge the first operating at visible wavelengths. We anticipate that now, when it has been realized experimentally, the spaser will advance our fundamental understanding of nanoplasmonics and the development of practical applications.

Analyte sensing made easy
rsc.org August 18th, 2009 Spanish scientists have made antibody-coated nanoparticles that can detect bioanalytes indicative of drug abuse. Ramón Alvarez-Puebla and colleagues at the University of Vigo attached antibodies specific to a major cocaine metabolite, benzoylecgonine, to the surface of carbon nanotube-supported silver nanoparticles. They then added a solution of benzoylecgonine, which bound to the antibodies and caused a change in their structure. The team showed that surface-enhanced Raman spectroscopy (SERS) could be used to monitor the structural changes and determine the metabolite concentration. The method can be performed in biological fluids, such as saliva or urine, says Alvarez-Puebla, and can determine not only the drug's presence but also the amount consumed. It could also be used to detect disease-related biomolecules, he suggests.

Now, a minuscule rival for Viagra
taragana.com August 18th, 2009 By using nanotechnology - the science of tiny particles - researchers have created a fast-acting treatment for impotence that could rival Viagra. The treatment has so far only been tested in animals but the researchers behind it say the same approach could also benefit humans. Viagra and other drugs take time to show their effects, as they have to be taken orally. Some users can suffer side-effects such as headaches, facial flushing and indigestion, reports The Times. The nanoparticle approach, by contrast, worked in less than 10 minutes and its effects seem to be limited to the relevant parts of the body, according to the researchers. Kelvin Davies of the Albert Einstein College of Medicine in New York, who oversaw the research, said the results showed the potential for "nano-medicines".

China Reports the First Human Nano-Fatalities
popsci.com August 20th, 2009 Two women in China have achieved the dubious honor of being the first humans to be killed by nanotechnology. The women, who worked in a poorly ventilated factory spraying a paint that contained nanoparticles, reportedly inhaled the particles over a period of months. The tiny compounds infiltrated the workers' lungs and skin, causing lung damage, fluid buildup, and eventual respiratory failure. Five other women have been hospitalized for the same condition. Reuters quotes Yuguo Song, a Beijing toxicologist whose report appeared in European Respiratory Journal: The particles' size "means that they can penetrate the body's natural barriers, particularly through contact with damaged skin or by inhalation or ingestion," and once they've entered lung cells they cannot be removed.

UWSP professor makes nanotech discovery
wausaudailyherald.com August 20th, 2009 Research at the University of Wisconsin-Stevens Point could potentially revolutionize nanotechnology production and put Wisconsin at the forefront of the high-tech industry. Chemistry professor Michael Zach has developed a method of making large quantities of patterned nanowires by reusing the wire's template, like a rubber stamp. Typically, a pattern is destroyed in the making of one wire. Zach's process would drastically cut the time needed to create a significant number of nanowires. It currently takes about two and a half weeks to make a gram, Zach said, but his process trims that to about 13 hours, with potential for faster times. Cutting that time so significantly would allow scientists to expand their ideas on how to use the microscopic wires, which are commonly used in computer chips as conductors or semi-conductors.
