Synthesis and characterization of polymer-SWNTs: (a) scheme of polymer-SWNT synthesis using EDC-NHS chemistry and subsequent DNA loading; (b) ζ potential measurements of initial COOH-SWNT constructs, after conjugation with BPEI-25k via EDC-NHS chemistry and after addition of DNA; (c) scheme of polymer-SWNT synthesis using triazine chemistry and subsequent DNA loading; (d) ζ potential measurements of triazine-functionalized SWNTs, after conjugation with BPEI-25k via nucleophilic substitution and after addition of DNA.
