Abstract:
The present disclosure describes an optically powered transducer with a photovoltaic collector. An optical fiber power delivery method and system and a free space power delivery method are also provided. A fabrication process for making an optically powered transducer is further described, together with an implantable transducer system based on optical power delivery.
Abstract:
A printed circuit board structure is coated with an encapsulant within which microfluidic channels have been formed. The microfluidic channels are formed by soldering fluidic connections to metal traces on a surface of the printed circuit board structure prior to encapsulation. The metal traces are removed by etching after encapsulation to form microchannels within the encapsulant.
Abstract:
A printed circuit structure containing a fluidic chamber configured to receive an aqueous solution containing a sample to be analyzed and fluorophore for polymerase chain reaction analysis. The printed circuit structure also contains a heating element that provides for temperature cycling of the fluidic chamber to support polymerase chain reaction analysis.
Abstract:
Evaporative cooling is an effective and efficient method for rapidly removing heat from a system device. In accordance with the disclosure herein, a microfluidic Y-junction apparatus is provided which can produce low temperatures and can be integrated into microdevices.
Abstract:
Methods for differentially quantifying nucleic acids in a biological sample using differentially methylated loci include forming a digested biological sample in a solution of a methylation- sensitive restriction enzyme to cleave an unmethylated group of nucleic acids, forming a reaction mixture, amplifying the reaction mixture to generate a first signal from the a group of detection probes and a second signal from a second group of detection probes, determining a ratio comprising a first value derived from the first signal to a second value derived from the second signal, and identifying the proportion of nucleic acid in the biological sample originating from the first plurality of nucleic acids.

Abstract:
Methods and devices for sequencing nucleic acids are disclosed herein. Devices are also provided herein for measuring DNA with nano-pores sized to allow DNA to pass through the nano-pore. The capacitance can be measured for the DNA molecule passing through the nano-pore. The capacitance measurements can be correlated to determine the sequence of base pairs passing through the nano-pore to sequence the DNA.
