“…These values are above the average limit of detection by EDS which has been determined to be 0.12 wt % for oxygen. 41 Additionally, EDS of the negative binding control of BioMag-IgG/Ag 0 -(Cys) did not detect the presence of Ag 0 atoms consistent with a lack of antibody recognition and minimal nonspecific binding (see the Supporting Information).…”

Biomimetic Mineralization of Noble Metal Nanoclusters

A number of biological systems have developed highly orchestrated detoxification mechanisms toward the bioreduction and mineralization of noble metals. These systems incorporate small peptides and proteins as nucleation sites for metal binding and nanocluster stabilization. Herein, we present the use of biologically relevant ligands ranging from single amino acids (histidine, imidazole, and cysteine) to linear peptides (glutathione and a histidine rich peptide) in the stabilization of a variety of noble metal surfaces (Au(0), Ag(0), Pt(0), and Cu(0)). As a result, the different nanocluster/ligand combinations offered a broad range of sizes and stabilitites. The peptide coat also affords a unique functional handle for the formation of larger assemblies. Using Ni chelation and immunomolecular approaches, strategies for the assembly of nanocluster heterostructures were investigated.

“…The method involves bombarding a specimen with a focused high energy beam of electrons and analyzing the X-ray spectrum emitted from the sample. The X-rays are characteristic of the bombarded elements and allow determination of the quantitative composition of the test samples with wave-length dispersive spectrometers [119] [90]. With sectioned samples element analysis could be performed in subsurface areas with the electron beam hitting the sec-tioned surface perpendicular to the natural sample surface.…”

Various assessment techniques have been applied to evaluate the loss of dental hard tissue and the surface-softened zone in enamel induced by erosive challenges. In this chapter, the most frequently adopted techniques for analyzing the erosively altered dental hard tissues are reviewed, such as profilometry, measuring microscope techniques, microradiography, scanning electron microscopy, atom force microscopy, nano-and microhardness tests and iodide permeability test. Moreover, methods for chemical analysis of minerals dissolved from dental hard tissue are discussed. It becomes evident that the complex nature of erosive mineral loss and dissolution might not be comprehended by a single technique, but needs application of different approaches for full understanding.

Copyright © 2006 S. Karger AG, Basel Acid attack leads to an irreversible loss of the outermost enamel and dentin layers and to partial demineralization (softening) of the tooth surface. In enamel, the thickness of the softened layer is estimated to be 2-5 tJm [1,2] [1, 2]. The softened eroded tooth surface is highly susceptible to abrasive wear, and mechanical impacts such as toothbrushing can easily remove the superficially demineralized dental hard tissue [3][4][5] [3][4][5]. For simulating intra-oral erosion as closely as possible, it is desirable to assess the erosive effects on native tooth surfaces. Most of the methods described below need polished surfaces for precise assessment of the erosively induced defects or for creating reference surfaces, which means that the natural, often fluoridated surface of the tooth has to be removed. However, it should be considered that in the case of intra-oral erosion the outermost surface layers are also continuously removed by the acid attack, so that a 'polished' surface is Attin 2 cre-ated. When monitoring of erosive surface alterations within a period of time is performed, it could become necessary to fix a specimen in the measuring device i...
