I have prepared nanoparticle using (3-Aminopropyl)triethoxysilane (APTES), While doing TEM analysis for the prepared nanoprticle. I have encountered too much solvent background, which hinders the particle visibility.
while drop casting. I have noticed silane solution is forming thin sheet on the copper grid
* To avoid this issue i have diluted the sample 5 times. Still the same
* Used tissue paper to remove solution drop from the copper grid after 30 min. Still i faced the same issue. Unable to take good picture. Kindly someone advise me on this. Thanks in advance !
- I have also attached sample TEM image for the reference
Can you heat up your samples to dry out? Make sure to remove solvents before taking TEM images?
You can also try different cleaning methods such as UVOC or plasma cleaning. I have personally had success removing solvents from nanosheet materials which were extremely difficult to remove with washing.
Good Luck!
