X-Ray Microscopy at Suboptical Resolution: Direct Observation of the 65-nm Periodicity in Collagen Fibrils.
نویسندگان
چکیده
Using a Fresnel zone plate we demonstrate for the first time the direct visualization by x-ray microscopy of suboptical regularity in a biological specimen, namely the 65-nm axial periodicity of tendon collagen. This resolution test demonstrates a resolving power of about 20λ; a resolving power of <10λ is in prospect.

Fibrous long spacing collagen ultrastructure elucidated by atomic force microscopy.
Fibrous long spacing collagen (FLS) fibrils are collagen fibrils in which the periodicity is clearly greater than the 67-nm periodicity of native collagen. FLS fibrils were formed in vitro by the addition of alpha1-acid glycoprotein to an acidified solution of monomeric collagen and were imaged with atomic force microscopy. The fibrils formed were typically approximately 150 nm in diameter and ...
متن کاملAtomic force microscopic studies of isolated collagen fibrils of the bovine cornea and sclera.
Isolated collagen fibrils from the bovine cornea and sclera were investigated by atomic force microscopy (AFM) in a non-contact mode. AFM imaging visualized the surface topography of both corneal and scleral collagen fibrils with quantitative information on their height and width. The corneal collagen fibrils had a height of 15.6 +/- 1.5 nm and a D-periodicity of 63.9 +/- 0.5 nm. On the other h...

Nano-crystalline particles of CeO2 have been synthesized by a low temperature chemical precipitation method. The precursor materials used in this research were Ce(NO3)3.6H2O, NaOH and diethylene glycol as surfactant. X-ray powder diffraction results showed that face centered cubic CeO2 nanoparticles with crystalline size in nanometer scale were formed. Scanning electron microscopy measurement s...
متن کاملSimple synthesis of new nano-sized pore structure vanadium pantoxide (V2O5)
New forms of vanadium oxide Nanoporous were fabricated using a simple chemical synthesis method. Vanadium pentoxide (V2O5) Nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM) and X-ray diffraction (XRD), Four...
