  • Generation of biomaterial microarrays by laser transfer
    Patent number: 6936311
    Abstract: A method for creating a microarray of biomaterial 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 biomaterial 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.
    Type: Grant

  • Generation of viable cell active biomaterial patterns by laser transfer
    Patent number: 6905738
    Abstract: 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.

  • Matrix assisted pulsed laser evaporation direct write
    Patent number: 6766764
    Abstract: An device for depositing a transfer material onto a receiving substrate includes a source of pulsed laser energy, a receiving substrate, and a target substrate. The target substrate comprises a laser transparent support having a back surface and a front surface. The front surface has a coating that 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 pulsed laser energy, it is more volatile than the transfer material. The source of pulsed laser energy is be positioned in relation to the target substrate so that pulsed laser energy is directed through the back surface of the target substrate and through the laser-transparent support to strike the coating at a defined location with sufficient energy to volatilize the matrix material at the location, causing the coating to desorb from the location and be lifted from the surface of the support.

  • Fabrication of conductive/non-conductive nanocomposites by laser evaporation
    Patent number: 6660343
    Abstract: A composite layer of a sorbent, chemoselective, non-electrically-conducting polymer and nano-particles of an electrically conducting material dispersed throughout the polymer is formed on a substrate by pulsed laser deposition, matrix assisted pulsed laser evaporation or matrix assisted pulsed laser evaporation direct writing.
