Solaris Nanoscience Publishes New Regime of Nanoparticle Response

Dec 02, 2004, 00:00 ET from Solaris Nanosciences Corporation

    PROVIDENCE, R.I., Dec. 2 /PRNewswire/ -- Solaris Nanosciences Corporation
 today announced that breakthrough work by its founder and CEO, Nabil Lawandy
 has been published in the Journal of Applied Physics Letters. The letter
 entitled "Localized Surface Plasmon Singularities in Amplifying Media"
 appeared in the November 22, 2004 edition.
     The paper has importance in the exploding field of nanotechnology and has
 connections to several other fields, ranging from random lasers to single
 molecule biological assays.  "Plasmons were observed as far back as the 4th
 Century AD by the Romans using metallic nanoparticles of silver and gold to
 color glass," said Dr. Lawandy. "This work, along with the discovery of lasers
 and light amplification, shows how this age old phenomena can create a whole
 new regime of physics and set of applications for metal nanostructures."
     "This paper describes an important insight regarding the interactions
 between plasmon resonant and gain media which will no doubt lead to new
 innovations and applications in the field of nanophotonics," said Naomi Halas,
 the Stanley C. Moore Professor in Electrical and Computer Engineering and
 Professor of Chemistry at Rice University, and a leading research scientist in
 the field of nanotechnology and its biological applications.
     Vladimir Shalaev, the Robert and Anne Burnett Professor of Electrical and
 Computer Engineering at Purdue University said, "the field of plasmonics is
 currently playing an increasingly important role in nanophotonics and various
 sensing applications. This is because oscillations of free electrons,
 plasmons, in metal nanoparticles can 'focus' the electromagnetic energy of
 light onto the nanoscale leading to dramatically enhanced local fields. The
 level of achievable enhancement is limited by damping of plasmon oscillations.
 Recently, Lawandy showed that by placing metal nanoparticles in amplifying
 media, the damping of plasmons can be compensated by gain provided by a host
 material so that the local field can reach truly gigantic magnitudes. This
 discovery may have a revolutionary impact on the field of nanophotonics and
 result in novel spectacular applications of plasmonic nanomaterials, for
 example, for sensing molecules with unprecedented sensitivity."  Dr. Shalaev
 is well established expert in the field of nanotechnology electromagnetics.
