The structures of resulting thin films are studied using atomic force microscopy. Clusters with more than ∼600 atoms form thin films, in which the clusters are not completely merged but survive as individual ...
WebCAS-No.: 7440-44-0 Highly oriented pyrolytic graphite (HOPG) is a metal consisting of multiple layers held together via Van der Waals forces. Individual 2D layers can be easily cleaved and exfoliated from the stack. Each layer looks like a mosaic of microscopic crystal grains of varying sizes.

WebFeb 8, 1991 · Highly ordered pyrolytic graphite (HOPG) is the substrate often used in scanning tunneling microscope (STM) studies of biomolecules such as DNA. All of the images presented in this article are of freshly cleaved HOPG surfaces upon which no deposition has occurred. WebFeb 1, 2013 · Highly ordered pyrolytic graphite (HOPG) specimens embedded in acid-proof high-density polyethylene were treated in the acid mixture at 100 °C for between one to four days. The degree of HOPG damage could be seen by transmission and scanning electron microscopy, X-ray photoelectron and Raman spectroscopy, and X-ray diffraction.
WebIn this study, we investigate the influence of glow discharge plasma (GDP) on the self-assembly, morphology and binding affinity of streptavidin coated gold nanoparticles (Au-NP-SV) and biotinylated antibody (bAb) adsorbed on a highly oriented pyrolytic graphite (HOPG) substrate. Atomic force microscope (AFM) was used to image the pre- and post-GDP …
