  • Real-Time Pcr Detection of Microorganisms Using an Integrated Microfluidics Platform
    Publication number: 20080125330
    Abstract: A portable, fully-automated, microchip including a DNA purification region fluidly integrated with a PCR-based detection region is used to detect specific DNA sequences for the rapid detection of bacterial pathogens. Using an automated detection system with integrated microprocessor, pumps, valves, thermocycler and fluorescence detection modules, the microchip is able to purify and detect bacterial DNA by real-time PCR amplification using fluorescent dye. The fully automated detection system is completely portable, making the system ideal for the detection of bacterial pathogens in the field or other point-of-care environments.

  • Micro-lens array and method of making micro-lens array
    Patent number: 7042645
    Abstract: A micro-lens array and a method for making are described. The micro-lens array includes a base element and a plurality of lenses formed of an epoxy and including nanoparticles. The micro-lens array is formed from a master micro-lens array, which is placed within a replica micro-lens making assembly. The master micro-lens array is coated with an anti-stiction material prior to having an elastomeric material positioned over it and cured. Removal of the elastomeric material provides a plurality of cavities, which are filled with an epoxy including nanoparticles. Curing of the epoxy finishes the fabrication of the micro-lens array. The lenses of the micro-lens array are formed from a colloidal suspension of nanoparticles and resin.
