How to separate nanoparticles from nanobiocomposite for TEM analysis?
Lopez Tellez et al., 2013 (http://www.ncbi.nlm.nih.gov/pubmed/23755691)
have used acetone for separating nanorods from orange peel, and ultrasonicated the mixture prior to TEM analysis.
What could be the principle behind using acetone for the separation? Can any other solvent or any other technique be used for separating nanoparticles from nanobiocomposite?
