  • Micro-fabricated stamp array for depositing biologic diagnostic testing samples on bio-bindable surface
    Patent number: 8133455
    Abstract: The present invention discloses micro-stamp array supported on a substrate comprising a plurality of micro-stamp sticks. Each of the micro-stamp sticks includes a micro-stamp-stick head having a channel opened through a central portion in each of the micro-stamp sticks. Each of the micro-stamp-stick heads is attached to a tapered guide tube surrounded by tapered guide-tube walls wherein the tapered guide tube is in hydraulic communication with the micro-stamp-head channel. The micro-stamp array further includes a filler chip that includes a filler reservoirs disposing on top of the tapered guide tubes, each of the filler reservoirs having a refill channel opened to the tapered guide tube for refilling the tapered guide tube and the channels.
