Apple iPhone apps put Nanotechnology in your pocket

The Project on Emerging Nanotechnologies (PEN), established in April 2005 as a partnership between the Woodrow Wilson International Center for Scholars and the Pew Charitable Trusts (Washington) has developed findNano, an application for Apple’s iPhone and iPod Touch that lets users discover and determine whether consumer products are nanotechnology-enabled ranging more than 1,000 different products from consumer electronics, toys or food to improved drug delivery systems.

This application takes as base, the PEN’s “Consumer Products Inventory”, which is one of the leading sources of information on manufacturer-identified nanotechnology consumer products around the world and through this new application becomes more accessible for today’s consumers.

Patrick Polischuk, Research Associate at PEN says: “This innovative tool satisfies the needs of citizen, scientists, tech-savvy consumers, and those who are merely curious about whether products contain nanomaterials.”

To help develop better estimates of the number of nano-based products in commerce, the iPhone app allows users to submit information on new products, including product name and where the product can be purchased. Using the built-in camera, iPhone users can even submit new nanotech product to be included in future inventory updates. This feature will help consumers, researchers, etc to determine how and where nanotechnologies are entering the marketplace.

findNano is available as a free download for the iPhone and iPod Touch, and can be found in the iTunes App Store.

The Universidad Politécnica de Madrid has submitted a patent application for a device for intermediate band infrared photodetector and quantum dots.

The invention relates to an infrared photodetector containing a region with semiconductor quantum dots. This region with n-type doping is between two semiconducting layers n and p type.

The absorption of infrared photons causes the appearance of a voltage between the contacts of the device or the production of an electric current, making possible the detection of infrared light.

Researchers at the Institute of Photonic Sciences (ICFO) in collaboration with researchers from the CSIC-Optics Institute of Madrid have developed a ultraconcentrated light nanolantern through a resonant optical antenna. This antenna consists of two gold bars of 500 nm each.  

With this nanolantern it has been possible to catch 200 nanometers in size polystyrene droplets. In addition, there have been experiments that show that were intercepted E. coli bacteria without affecting their biological parameters, which was not possible using other techniques.
