这是原始文献中用来表征这种颗粒的AFM方法：
The sample of dsDNA or ssDNA (10 μl) was deposited onto a freshly cleaved mica surface (Ted
Pella, Inc.) and left to adsorb for 10 min. Then 10 mM MOPS (12.5 mM Mg2+) (500 μl) was
added to the liquid cell and the sample was scanned in a tapping mode using Agilent AFM
series 5500 (Agilent Technologies, USA) with 0.08 N/m force constant cantilever of a Silicon
nitride cantilevers with sharpened Pyramidal tip (OMCL-TR400PSA, Olympus, Atomic Force
F&E GmbH, Mannheim, Germany). After engagement the tapping amplitude set point was
typically 2.0 volts and the scan rates ranged from 1-2 Hz. During the liquid AFM imaging the
better imaging was in most cases obtained with minimal loading forces applied and optimized
feedback parameters. Several AFM images, all 512 × 512 pixels, were obtained from separate
locations across the mica surfaces to ensure reproducibility of the results. All the images were
analyzed by using Gwyddion 2.16 software.
我看了，貌似没什么制样过程。你们帮我研究一下，难度在哪里？我打算请公司或者高校的人帮我做。作者: hcy517 时间: 2016-2-7 16:49 标题: 【回复】
