Abstract
The present invention relates to single cell array micro-chips and fabrication, electrical measurement and electroporation method thereof. The single cell array microchip comprises a substrate (), a plurality of positioning electrodes () formed in an array, a plurality of measuring electrode-pairs () formed in an array, and a micro sample pool (). The invention integrates cell array positioning with electrical measurement and electroporation for living cells, which is characteristic of label-free and noninvasive methods to manipulate, position particles/cells as well as further measure their electrical parameters. Therefore, single-cell-array positioning and multi-mode in-situ real-time measurement can be realized for intensive analysis. Since the positioned cells are immobile, the precision of the electrical measurement of cells is effectively improved, so is the efficiency of electroporation with lower cell mortality rate.
