Anti-HER-3 antibody was used for the first time in a disposable immunosensor based on indium tin oxide (ITO) substrate for HER-3 quantification. Anti-HER-3 was immobilized onto ITO substrate by 3-aminopropyl)triethoxysilane (APTES) and glutaraldehyde. This highly sensitive immunosensor was capable of detecting concentrations of HER-3 down to the femtogram/ml level by investigating changes in th...

Pure cobalt coatings were electrodeposited on copper substrate by means of direct electric current in a chloride solution at different current densities in the range of 10-70 mA cm -2 . The surface morphology and microstructure were investigated via X-ray diffraction analysis and scanning electron microscopy. Corrosion behavior of cobalt coatings was also studied in a 3.5 wt% NaCl soluti...

background and aims: in various clinical situations, mineral trioxide aggregate (mta) may come into direct contact with blood. the aim of the present study was to evaluate the effect of exposure to blood on marginal adaptation and surface microstructure of mta. materials and methods: thirty extracted human single-rooted teeth were used in this study. standard root canal treatment was carried ou...

morphological and electrophoretic analysis of the crystalline inclusions (parasporal crystals) of sporulated cultures of b. thuringiensis ssp. kumamotoensis dsm 6070 (bt 6070) was conducted via phase contrast and scanning electron microscopy and sodium dodecyl sulphate-polyacrylamide gel electrophoresis. the activity of the spore-crystal suspensions against house fly (musca domestica) larvae wa...

introduction: the aim of this in vitro study was to evaluate the effect of an experimental irrigation solution, containing two different concentrations of papain, tween 80, 2% chlorhexidine and edta, on removal of the smear layer. methods and materials: thirty-six single-rooted teeth were divided into two experimental groups ( n =12) and two positive and negative control groups of six. the cana...

introduction: smear layer (sl) is produced as a result of mechanical instrumentation of the canal(s). despite the controversies regarding its removal, the evidence-based trend has shifted towards removing and eliminating the sl. different methods have been used to remove the sl and the aim of this in vitro study was to evaluate the ability of 17% ethylenediaminetetraacetic acid (edta), 18% etid...

A conducting lithium aluminum germanium phosphate (LAGP) glass-ceramic with a formula of Li1.5Al0.5Ge1.5(PO4)3 was synthesized by melt-quenching method and subsequent crystallization at 850 °C for 8 h. The prepared glass-ceramic was characterized using differential scanning calorimetry (DSC), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and AC impedance techniqu...
