    摘要： A method for depositing a transfer material onto a receiving substrate uses a source of laser energy, a receiving substrate, and a target substrate. The target substrate comprises a laser-transparent support having a laser-facing surface and a support surface. The target substrate also comprises a composite material having a back surface in contact with the support surface and a front surface. The composite material comprises a mixture of the transfer material to be deposited and a matrix material. The matrix material is a material that has the property that, when it is exposed to laser energy, it desorbs from the laser-transparent support. The source of laser energy is positioned in relation to the target substrate so that laser energy is directed through the laser-facing surface of the target substrate and through the laser-transparent support to strike the composite material at a defined target location. The receiving substrate is positioned in a spaced relation to the target substrate. The source of laser energy has sufficient energy to desorb the composite material at the defined target location, causing the composite material to desorb from the defined target location and be lifted from the support surface of the laser-transparent support. The composite material is deposited at a defined receiving location on the receiving substrate. The method is useful for creating a pattern of biomaterial on the receiving substrate.

The composite material comprises a mixture of the biomaterial to be deposited and a matrix material.

The source of laser energy has sufficient energy to desorb the composite material at the defined target location, causing the composite material to desorb from the defined target location and be lifted from the support surface of the laser-transparent support. The composite material is deposited at a defined receiving location on the receiving substrate. The steps are repeated at successive defined target locations and successive defined receiving locations such that the composite material is deposited in a microarray of deposited composite material. The method is useful for creating, for example, a gene recognition array,

    摘要： A method of directing a pulse of laser energy though a workpiece. The workpiece has: a substrate that transmits the laser energy; focusing elements on a surface of the substrate proximal to the laser that focus the laser energy; and a coating on the substrate distal to the laser that absorbs a portion of the laser energy. Each focusing element focuses the laser energy to a point that removes or ablates a portion of the coating from the substrate to produce a hole in the coating.

    摘要： A fuel cell comprising an anode chamber, a cathode chamber, and a nanoporous membrane between the anode chamber and the cathode chamber, wherein the nanoporous membrane sequesters and isolates a microbe in the anode chamber. The nanoporous membrane allows nutrients to flow actively or passively from the cathode chamber to the anode chamber and can be modified by a thin film composite (TFC) to create a TFC nanofiltration membrane. The nanoporous membrane can have a pore size from about 100 nm to about 1000 nm. A method of making a fuel cell comprising configuring a nanoporous membrane between an anode chamber and a cathode chamber wherein the nanoporous membrane sequesters and isolates a microbe in the anode chamber and can be used to protect the cathode chamber.

    摘要： A device having: a chamber having a gas inlet, a gas vent, and a liquid vent; and a float and a weight coupled to the chamber. The float has a lower density than the chamber. The weight has a higher density than the chamber. The aggregate density of the chamber, the float, and the weight is greater than the density of the chamber. The gas inlet, the gas vent, the liquid vent, the float, and the weight are positioned on the chamber such that: when the chamber is filled with and submerged in a liquid in which the chamber is neutrally-buoyant, the chamber is oriented to place the gas vent below the gas inlet; and when a gas is introduced through the gas inlet into the chamber that is filled with the liquid, the chamber pivots to raise the gas vent until a portion of the gas escapes from the chamber through only the gas vent.
