SummaryThe three steps of the sulphide silver method have been examined: 1) Transformation of metals to metal sulphides; 2) Fixation and embedding or freezing of the tissue for sectioning; and 3)Expand
Biodistribution of gold nanoparticles in mouse lung following intratracheal instillation
BackgroundThe fate of gold nanoparticles, 2, 40 and 100 nm, administered intratracheally to adult female mice was examined. The nanoparticles were traced by autometallography (AMG) at bothExpand
Evidence that synaptically-released zinc contributes to neuronal injury after traumatic brain injury
Prior evidence indicates that synaptically-released zinc enters postsynaptic neurons in toxic excess during ischemia and seizures. In addition, prevention of this zinc translocation has been shown toExpand
Kupffer cells are central in the removal of nanoparticles from the organism
BackgroundThe study aims at revealing the fate of nanoparticles administered intravenously and intraperitoneally to adult female mice, some of which were pregnant. Gold nanoparticles were chosen as aExpand
Histochemical demonstration of heavy metals. A revised version of the sulphide silver method suitable for both light and electronmicroscopy.
The three steps of the sulphide silver method have been examined: 1) Transformation of metals to metal sulphides; 2) Fixation and embedding or freezing of the tissue for sectioning; and 3) DepositionExpand
Zinc-enriched (ZEN) terminals in mouse olfactory bulb
The present study was designed to localize zinc-enriched (ZEN) terminals in mouse olfactory bulb by means of ZnT3 immunocytochemistry (ICC) and zinc autometallography (AMG). The immunocytochemicalExpand
Inhibitory zinc-enriched terminals in mouse spinal cord
The ultrastructural localization of zinc transporter-3, glutamate decarboxylase and zinc ions in zinc-enriched terminals in the mouse spinal cord was studied by zinc transporter-3 and glutamateExpand
Autometallography. A new technique for light and electron microscopic visualization of metals in biological tissues (gold, silver, metal sulphides and metal selenides).
The autometallographic procedure represents a new technique that can substitute for the normal methods of physical development (PD). The physical developer (a solution of reducing substance, silverExpand

  • 1 March 1981
SummaryA detailed description is given of a method by which gold can be visualized in frozen, paraffin and Epon sections. Histological sections from animals treated with gold compounds are exposed toExpand
Silver enhancement of quantum dots resulting from (1) metabolism of toxic metals in animals and humans, (2) in vivo, in vitro and immersion created zinc-sulphur/zinc-selenium nanocrystals, (3) metal
Autometallographic (AMG) silver enhancement is a potent histochemical tool for tracing a variety of metal containing nanocrystals, e.g. pure gold and silver nanoclusters and quantum dots of silver,Expand
