Dispersion of MWCNT agglomerates in different media. CNT-L was dispersed by sonication in PBS, dispersion medium (DM) and DMEM, and then observed with a light microscope as described in Methods. Agglomerates were much more efficiently dispersed in DMEM than in PBS and dispersion medium. Bar = 50 μm. (TIF 579 kb)
