NONCHEMICAL MODIFICATION OF SUPPORTS FOR STUDIES OF BIOPOLYMERS BY ATOMIC-FORCE MICROSCOPY

Two simple procedures of DNA molecule fixation on mica for following i maging by the atomic force microscopy were developed. The distinctive features of the procedures are their simplicity, absence of chemical m odification stages, and the possibility to obtain the images in air un der relative high humidity. Comparison of the features of the images o btained indicated that the procedures developed were competitive with the procedures earlier suggested.
