Abstract: Scanning SQUID microscopy (SSM) has been developed in some groups to achieve both of the good spatial resolution and quantitative accuracy for magnetic imaging. We have developed scanning SQUID probe microscope using a fine permalloy probe and a high T c superconducting (HTS) SQUID. The microscope has two modes, a scanning tunneling microscope (STM)-SQUID mode for conductive
For the purposes of this newsletter, we will compare the characterization of the dimensions of Silica (Fig. 1.), Gold (Fig. 2.) , and Polystyrene (Fig. 3.) nanoparticles (two different sizes each) by atomic force microscopy (AFM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).

With a resolution of 5-10nm laterally and sub-nanometer vertically, AFM is a powerful measurement instrument for quantitative measurements of a surface. This powerful quantitative measurement is coupled with flexibility in sample surface: there are no requirements on a sample to be able to be measured by AFM except that it fits into the instrument.
According to the different working principles though, they have their own advantages and disadvantages when measuring specific properties of sample (Table \(\PageIndex{1}\)). STM requires an electric circuit including the tip and sample to let the tunneling current go through. Single crystals of V2O5(001) and V6O13(001) were imaged in ambient conditions by scanning tunneling microscopy (STM) and atomic force microscopy (AFM). Atomic-scale resolution images are compared 2015-03-31 STM technique to investigate the electrically non-conductive materials, like proteins.
Combination of high-resolution AFM with super-resolution Stochastic Optical Reconstruction Microscopy (STORM) Introduction Since its development in 1986, atomic force microscopy (AFM) has become a versatile tool in various fields of application. As a surface imaging technique it is traditionally used in materials research. Here, it is

Two of the most common are Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). While both techniques are capable of providing nanometer-scale information about a material, they are very different methods, and can be used to reveal different kinds of information.
