DESCRIPTION:Nanoparticles in the single digit nanometer range can be easil
 y isolated and studied with low optical powers using nanoaperture tweezers
 . We have studied individual proteins and their interactions with small mo
 lecules\, DNA and antibodies. Recently\, using the fluctuations of the tra
 pped object\, we have pioneered a new way to “listen” to the vibration
 s of nanoparticles in the 10 GHz – 1 THz range\; the approach is called 
 extraordinary acoustic Raman (EAR). EAR gives unprecedented low frequency 
 spectra of individual proteins in solution\, allowing for identification a
 nd analysis\, as well as probing their role in biological functions. We ha
 ve also used EAR to study the elastic properties\, shape and size of vario
 us individual nanoparticles.
