| 摘要 |
An apparatus for nucleic acid sequencing includes a nanochannel (10) and a conveying device (5), configured to move a nucleic acid strand (F) through the nanochannel (10). The conveying device (5) includes: a first electrode (15), a second electrode (16), and a third electrode (17), which are arranged along the nanochannel (10) so as to be in contact with a fluid occupying the nanochannel (10), the second electrode (16) being arranged between the first electrode (15) and the third electrode (17); and a control unit (20) configured to apply a first voltage (V 1 ), a second voltage (V 2 ), and a third voltage (V 3 ), respectively, to the first electrode (15), the second electrode (16) and the third electrode (17), so as to control movement of the nucleic acid strand (F) through the nanochannel (10). |
