Scanning probe characterization of enzymes deposited onto step-bunched silicon nanostructures (original) (raw)

Physica Scripta, 2009

Abstract

Step-bunched Si surfaces with step heights of ~3 nm have been prepared as substrates for immobilization of the enzyme reverse transcriptase of the avian myeloblastosis virus. Tapping mode atomic force microscopy has been used for imaging. Calibration experiments using the carrier solution without the enzyme show the preservation of the surface without organic contamination. Upon enzyme deposition, two specific shapes
