Abstract:
1. A process for manufacturing a disposable multi-chamber chip, each chamber having low thermal capacity and good thermal isolation from its neighbors, comprising; providing a mold, shaped to form in a surface that conforms to said mold, micro-channels and an array of flat bottomed depressions having a depth no greater than 500 microns; placing at least one sheet of a first plastic material, having a first softening temperature, on said mold surface; on said first plastic material, placing a sheet of a second plastic material that has a second softening temperature that is less than said first softening temperature; heating all materials to said second softening temperature whereby said first plastic material does not melt; applying uniform pressure between said plastic sheets and said mold whereby said second plastic material flows, thereby forcing said sheet of first plastic material to conform to said mold surface; then cooling until said second plastic material has fully hardened; and separating said plastic materials one from another and then removing the sheet of first plastic material from the mold, thereby forming said disposable multi-chamber chip.
