  • Publication number: 20140030819
    Abstract: Systems and methods for molecular sensing are described. Molecular sensors are described which are based on field-effect or bipolar junction transistors. These transistors have a nanopillar with a functionalized layer contacted to either the base or the gate electrode. The functional layer can bind molecules, which causes an electrical signal in the sensor.

  • Publication number: 20140026413
    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.

  • Publication number: 20130327645
    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.

  • Publication number: 20130323716
    Abstract: This disclosure provides methods, systems, compositions, and kits for the multiplexed detection of a plurality of analytes in a sample. In some examples, this disclosure provides methods, systems, compositions, and kits wherein multiple analytes may be detected in a single sample volume by acquiring a cumulative measurement or measurements of at least one quantifiable component of a signal. In some cases, additional components of a signal, or additional signals (or components thereof) are also quantified. Each signal or component of a signal may be used to construct a coding scheme which can then be used to determine the presence or absence of any analyte.

  • Publication number: 20130230063
    Abstract: A microlaser system includes an optical source, a microlaser, an actuator switch, and a photovoltaic power source. The microlaser, which includes a control element, is optically pumped by at least a portion of light emitted by the optical source. The actuator switch is configured to be activated by a triggering event. Furthermore, the photovoltaic power source is coupled in a series connection with the actuator switch and the control element, the series connection configured to connect the photovoltaic power source to the control element of the microlaser when the actuator switch is activated by the triggering event.

  • Patent number: 8506863
    Abstract: A method for adhering two layers of materials is described. An additional layer of material deposited on one of the layers is used. The additional layer of material is perforated and undercut by etching away one of the layers thereby generating anchor shaped holes. The other layer is then deposited on the additional layer filling the anchor shaped holes therefore, providing adhesion.
