For solid sample, its surface should be flat with nanoscale roughness. The dimension can be 1cm*1cm or bigger. For the liquid sample like nanoparticles, the sample should be dropped onto a flat substrate like silica wafer or mica, and the sample can be measured after it is dried. For the force spectroscopy measurement, it is necessary to contact with Dr. Wei or Miss. Li before the experiments because there are special needs for the modification of substrates and AFM probes.
