Covalent functionalization: chemical procedure<br />
1. step: acid treatment => carboxyl end-groups<br />
• <strong>nanotubes</strong> are usually endcapped<br />
• length up to several microns<br />
Ultrasonification in H 2SO 4/ H 2O 2 or in H 2SO 4/ HNO 3<br />
+ filtration<br />
• <strong>nanotubes</strong> with open ends<br />
• shortened in length<br />
• „clean“ solution
