We describe the fabrication process for an anode of a miniaturized transmission electron microscope. The anode consists of a very thin membrane (membrane-anode) that encloses the electron optics microsystem and it is used to separate the high vacuum part from the sample chamber in the microscope. The membrane-anode is made of Si3N4 layer deposited on an oxidized silicon substrate and was fabricated...
Carbon nanotubes (CNTs) have been widely investigated as one of the most promising nanomaterials in biomedical applications. Functionalization of CNTs with poly(ethylene glycol) diamine (PEG) is a recognized methodology with good solubility and biocompatibility. In this study, PEG conjugated (PEGylated) multi-walled CNTs (MWCNTs) were prepared and labeled with fluorophore FITC. Using fluorophore-conjugated...
The model of different level sub-chronic aluminum (Al)intoxication in chickens was established by continuous peritoneal injection of various gradient aluminum trichloride (AlCl3). The growth index of cerebrum was measured and the morphological structure of it was observed by optical microscope and transmission electron microscope. The results showed that:(1)The growth index of cerebrum was lower in...
