Characterization of DNA aptamer probe attachment to PEGylated nanoparticle. (A) Zeta potential measurements after PEGylation, conjugation of conjugation-annealing handle, and annealing of DNA aptamer probe. Data are means ± standard deviation of one experiment, analyzed in triplicate. (B) qPCR quantification of aptamer numbers for particles functionalized with complementary polyA aptamer or non-complementary (negative control) polyT aptamer. Data shown are means ± standard deviation, n = 3.
