Fabrication of nanometre-scale structures in short timescales and with high throughput has great importance in the future of nanoscale science and technology. We show that the local oxidation of hydrogen-passivated silicon surfaces by intermittent-contact mode atomic force microscopy can be applied on timescales as low as 500ns to create single oxide nanostructures with dimensions of 0.6×15nm ...
Atomic force microscope (AFM) was exploited to take picture of the molecular topology of C-reactive protein (CRP) in phosphate-buffered saline (PBS) solution. An explicit molecular image of CRP demonstrated a pentagonal structure composed of five subunits. Dimensions of the doughnut-shaped CRP molecule measured by AFM were about 25nm in outside diameter and 10nm in central pore diameter, and the height...
