Abstract

The glass nanopore produced by the physical method has better physical characteristics, higher strength, stronger stability, longer life and other significant features compared with the chemical method. The purpose of this paper is to study DNA sequencing (973 project) to provide experimental basis for preparation of glass capillary 5nm 3D nanochannel In this paper, we design a set of glass capillary tension system which is controlled by laser heating and linear ultrasonic motor and produced successfully the device for the preparation of nanopore below 50 nm. In addition, the use of micro droplet generation system has carried out preliminary characterization of nanopore drawn devices. Seen from the characterization, the nanopore device fabricated can indeed produce a through-hole.
