  • Silicon nanoparticle for photodynamic cancer treatment utilizing quantum dot optical properties
    Patent number: 9592292
    Abstract: Quantum active sized silicon nanoparticles with a silicon core covered by a thin 0.5-1.5 nm oxide/nitride shell are described for light exposure in the 300-600 nm range for transforming atmospheric oxygen to singlet oxygen for causing cell apoptosis as a type of photodynamic cancer therapy. A method of use of the nanoparticle in a non-hydrophobic cream is also taught along with a blocking scheme for controlled reaction of the nanoparticle.
    Type: Grant
    Filed: February 29, 2016
    Date of Patent: March 14, 2017
    Inventors: James Beckman, Anatoli Ischenko
  • Ultra-violet radiation absorbing silicon particle nanoclusters
    Patent number: 9402791
    Abstract: Silicon particle nano-clusters formed with crystalline cores and amorphous shells are used for absorbing ultraviolet wavelength radiation. Silicon nano-particles are synthesized by plasma-chemical sputtering of bulk silicon crystal to form particles which are then quenched in an atmosphere of oxygen or oxygen and nitrogen. Analysis of these particles is presented for their scattering and absorption properties for use as ultraviolet protection elements.
