| dc.description | The synthesis of Au, Ag and Cu metal nanoparticles in 2-ethoxyethanol and 2-propanol supported in carbon nanotubes is reported. The synthesis was carried out by chemical liquid deposition (CLD) at 77K to obtain metal colloids. The metal supported in carbon nanotubes was obtained by solvated metal atom dispersed (SMAD) method. The composites were characterized by electron microscopy with electron diffraction, scanning electron microscopy, elemental analysis, thermogravimetry, infrared spectroscopy (FTIR). The quantum dots size in 2-propanol and carbon nanotubes supported are: silver 4.37 nm and copper 2.56 nm. In 2-ethoxyethanol solvent: silver 4.14 nm, copper 2.47 nm and gold 5.30 nm. The transmission electron microscopy (TEM) images confirm the presence of quantum dots inside and outside the carbon nanotubes. The samples demonstrate a thermal stability until 295°C. The FTIR exhibit the presence of solvent residues in the samples. The electron diffraction is observed in the silver and copper in 2-propanol supported in carbon nanotubes and in the silver sample for 2-ethoxyethanol. The histological analyses of rainbow trout (Oncorhynchus mykiss) after being injected with gold quantum dots in 2-ethoxyethanol, in concentrations 0.5 and 0.3x10-3 M do not exhibit cell disruption showing hepatocytes with morphology according to the normal for that specie. | en-US |
