I made copper nanoparticle from ascorbic acid. For scanning electron microscope, I kept a drop of copper nanoparticle on SEM sample plate. But it seems, aggregated in one point and that point couldn't dry. Same things happened when i mixed with dopamine and dropped on glass electrode surface. the droplet didnt dry? I diluted the concentration of CuNp but still it didn't work. Anybody has any solution?
Hi Jahowa, please try acetone. it may work for drying samples. Also you can use a hot gun blower (hair dryer) to try your samples. If it still does not dry, something interesting happening there.
Thanks Sir. Yes!I tried everything. I kept sample in desiccator but it didn't dry though the amount is very small( micro liter). Also made it heat by hair dryer and also left it for few days. but it didn't dry. Even i kept sample in oven at 45 degree but it didn't dry.
Dear Islam,
Your sample is dried when your solvent is vaporized. Where, dopamine can not be vaporized, becuase it does not have a boiling point ( decomposes before vaporize). Accordingly, you have to change it.
Best regards
