APPLICATION OF NANOTECHNOLOGY     Nanoparticles are being used in a number of industries. Nanoscale materials are used in electronic, magnetic and photographic, biomedical, pharmaceutical, cosmetic, energy catalytic and materials applications. Here are several we would like to introduce.
Colortized - NIST researchers have genetically engineered smooth muscle cells that can help in evaluating biocompatible materials such as blood vessel stents. This is a colorized image of a fully extended smooth muscle cell.
  
kasianowicz- Crystal structure of a biological nanopore. NIST researchers are studying ways in which biological or synthetic nanopores may one day be used to analyze DNA or to detect chemical or biological agents. (Data Credit: Song, et al. 1996. Science 274, 1859)

crystac-A crystal of beryllium ions formed from a laser-cooled plasma.
  
Locaseio - The stained bacterial cells shown in this image are part of a prototype - lab on a chip- sensor system designed by NIST scientists and collaborators. The cells adhere to posts constructed within microscopic channels of a plastic sensor device. The blue, green, yellow, and orange colors reflect increasing densities of e.coli cells, which eject potassium in the presence of certain chemicals.

allienegg - Computer simulation showing tornado-like vortices forming within a spinning Bose-Einstein condensate. BEC's are a new state of matter in which a collection of atoms behaves like one uniform -superatom-. This NIST simulation helped confirm that BEC's are superfluids¡Xa kind of liquid/gas that flows without friction.
  
baker - Chromosomes tagged with red and green fluorescent probes on chromosome 5. By chemically treating chromosomes extracted from a patient's blood sample and looking for breaks in chromosome 5, researchers hope to be able to predict a person's susceptibility to lung cancer.

Magnetic Monet. This graphic shows the magnetic 'domains' advanced material for making non-volatile logic devices. Changes in color indicate changes in the direction of the magnetization of the material. Housed in an AML metrology wing 12 meters (40 feet) underground, the NIST-developed instrument that recorded this data is the highest resolution magnetic imaging instrument in the United States.
  
Explosive Hot Pad. An infrared image shows temperature variations as a round swipe cloth is heated to vaporize any explosive particles that may be present. Black/deep purple areas are about 40 degrees C, while yellow/white areas are about 200 degrees C. NIST chemists are developing standards and calibration services to help optimize equipment used at airports and other venues for detecting explosive materials.
