Protein adsorption on MWCNT. MWCNT preparations, dispersed in 0.05 wt% BSA, were incubated at the concentration of 128 μg/mL for 1 h in culture medium with or without 10% FBS. At the end of the incubation, the suspensions were centrifuged, and adsorbed proteins quantified (A) or separated and stained (B) as described in Section 2. For (A), data are means ± SD of 4 independent determinations. *p < 0.05, **p < 0.01 vs. REF. For (B) a representative experiment, performed twice with comparable results is shown.
