摘要:

A procedure has been developed in which mercurated DNA is covalently bonded to a modified graphite surface. This technique allows for stable adhesion of the DNA which enables one to image it with the scanning tunneling microscope. The method is outlined in this paper and images are presented of a partially modified graphite surface and one completely modified with DNA attached. The DNA images demonstrate B‐helix periodicity.
