  • Nanoparticle heating and applications thereof
    Publication number: 20070164250
    Abstract: This invention provides magnetic nanoparticles, which when placed in a magnetic field are selectively heated at a certain frequency of the magnetic field, as a function of their size, composition, or both. The invention also provides for use of such nanoparticles, in applications including, inter alia, selective nanoparticle heating and applications thereof, hyperthermia induction in cells or tissue, remote alteration of protein structure and/or drug delivery.

  • Microwave stripline applicators
    Patent number: 6759808
    Abstract: An apparatus and method which maintains plasma discharges (for instance 25) in containers (for instance 20) which have an internal section of 1 cm or less in width are described. The very small cross-section plasma discharges are useful in MEMS devices, in spectrometers and in spectroscopy.
