Most clinical studies recommend the use of HbA1c assays that are traceable to the DCCT assay. [55] The National Glycohemoglobin Standardization Program (NGSP) and IFCC have improved assay standardization. [37] For initial diagnosis of diabetes, only HbA1c methods that are NGSP-certified should be used, not point-of-care testing devices. [36]
Non-contact atomic force microscopy (nc-AFM), also known as dynamic force microscopy (DFM), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close (order of Angstroms ) to the surface under study, the probe is then raster scanned across the surface, the image is then ...
MFM images of 3.2 Gb and 30 Gb computer hard-drive surfaces. Comparison of Faraday-effect image (left) and MFM image (inset, lower-right) of a magnetic film. Magnetic force microscopy (MFM) is a variety of atomic force microscopy, in which a sharp magnetized tip scans a magnetic sample; the tip-sample magnetic interactions are detected and used to reconstruct the magnetic structure of the ...
Electrostatic force microscopy (EFM) is a type of dynamic non-contact atomic force microscopy where the electrostatic force is probed. ("Dynamic" here means that the cantilever is oscillating and does not make contact with the sample). This force arises due to the attraction or repulsion of separated charges.

A non-contact force is a force which acts on an object without coming physically in contact with it. [1] The most familiar non-contact force is gravity, which confers weight. [1] In contrast, a contact force is a force which acts on an object coming physically in contact with it. [1] All four known fundamental interactions are non-contact ...
