Stanford researchers harness nanoparticles to track cancer-cell changes
Date:4/14/2009

lasers emit. These patterns, or Raman signals, occur when energy levels of electrons are just barely modified by weak interactions among the constituent atoms in the molecule being inspected.

Raman signals are emitted all the time by various molecules, but they're ordinarily too weak to detect. To beef up their strength, the Stanford team employed specialized nanoparticles produced by Intel Corp., each with its own distinctive signature. Intel has designed more than 100 different so-called COINs, or composite organic-inorganic nanoparticles: These are essentially sandwiches of dye molecules and atoms of metals such as silver, gold or copper whose reflective properties amplify a dye molecule's Raman signals while filtering out its inherent fluorescent response. The signals are collected and quantified by a customized, automated microscope.

Shachaf anticipates being able to demonstrate simultaneous visualization of nine or 10 COIN-tagged cellular features in the near future and hopes to bring that number to 20 or 30, a new high, before long. "The technology's capacity may ultimately far exceed that number," she added. Some day it could be used for more than 100 features. Meanwhile, another group outside Stanford, now collaborating with the Nolan group, has developed a prototype device that can detect Raman signals in a continuous flow of single cells, analogous to flow cytometry but with higher resolving power, Shachaf said.
