Its one of the tactic procedure to get good TEM image if the sample is magnetic nanoparticle without surface functionalisation. Suggest me a solvent or way of sample preparation without any agglomerationon the TEM grid?

1. MAKE DILUTE DISPERSION OF YOUR NANOPARTICLES IN ETHANOL

2. SONICATE THE DISPERSION for 10 MIN

3. TAKE 1 ML OF THE DISPERSION IN EPPENDROF  MICRO CENTRIFUGE TUBE AND YOUR TEM GRID

4. CENTRIFUGE THE DISPERSION FOR 3 MIN

5. CAREFULLY TAKE OUT THE GRID IN GLASS PETRIDISH AND KEEP IN VACCUUM DESICATOR OVERNIGHT.

6. YOUR GRID IS READY FOR TEM ANALYSIS WITHOUT AGGLOMERATION.

7. GOOD LUCK

Thank you

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
