Sketch of a typical gold nanoparticle encased in dendrons. A single sulfur atom at the root of each multiply branched dendron anchors it to the gold nanoparticle at the center. NIST and NCI/NCL researchers are studying the tiny constructs as a test bed and basic vehicle for many possible biomedical applications. Nanoparticles are particles between 1 and 100 nanometers in size. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties. Particles are further classified according to diameter. Nanoparticle research is currently an area of intense scientific interest due to a wide variety of potential applications in biomedical, optical and electronic fields.
