font size="1" face="GulliverRM"> We report for the first time the use of polyhistidine (Polyhis) to efficiently disperse multiwall carbon nanotubes (MWCNTs). The optimum dispersion MWCNT?Polyhis was obtained by sonicating for 30 min 1.0 mg mL−1 MWCNTs in 0.25 mg mL−1 Polyhis solution prepared in 75:25 (v/v) ethanol/0.200 M acetate buffer solution pH 5.00. The dispersion was characterized by s
