Fig 6. SDS-PAGE and silver staining of sonicated samples of lysozyme-SWCNTs, lanes 1 and 4 are free lysozyme, and lane 3 is SWCNTs, lane 2, 9, and 10 are sonicated conjugated lysozyme-SWCNT samples for 3, 7, and 10 min, respectively.
It is clear the conjugated SWCNTs are separated based on their lengths.
