Vector piezoresponse force microscopy.
A novel approach for nanoscale imaging and characterization of the orientation dependence of electromechanical properties-vector piezoresponse force microscopy (Vector PFM)-is described. The relationship between local electromechanical response, polarization, piezoelectric constants, and crystallographic orientation is analyzed in detail. The image formation mechanism in vector PFM is discussed...
متن کاملComparative Study of Clinical Staging of Oral Submucous Fibrosis with Qualitative Analysis of Collagen Fibres Under Polarized Microscopy
Background & Objectives: Oral submucous fibrosis (OSMF) is a condition where excessive deposition of dense collagen fibers occurred in the connective tissue of oral mucosa. An alteration of collagen necessitates an in depth understanding of collagen in oral tissues as no breakthrough studies have been reported. Therefore the aim was to correlate the clinical, functional and histopathol...
متن کاملImaging of in Vitro Collagen Fibers by Atomic Force Microscopy
The aim of this research was to investigate the use of atomic force microscopy (AFM) for the high-resolution imaging of collagen fibers in aqueous media. Collagen plays a vital role in many processes in vivo, especially in structural integrity, yet few studies have used AFM to investigate the structure of these fibers. Type I collagen was used in this study on AP-mica, poly-L-lysine-coated glas...
متن کاملElectrostatic-free piezoresponse force microscopy
Contact and non-contact based atomic force microscopy (AFM) approaches have been extensively utilized to explore various nanoscale surface properties. In most AFM-based measurements, a concurrent electrostatic effect between the AFM tip/cantilever and sample surface can occur. This electrostatic effect often hinders accurate measurements. Thus, it is very important to quantify as well as remove...
متن کاملElectron microscopy shows periodic structure in collagen fibril cross sections.
X-ray diffraction was used to monitor the effects of electron microscope fixation, staining, and embedding procedures on the preservation of the three-dimensional crystalline order in collagen fibrils of rat tail tendon. A procedure is described in which the characteristic 3.8-nm lateral spacing is preserved, with increased contrast, in the diffraction pattern of the embedded fiber. This spacin...
