Agarose gel electrophoresis of nanobarcoded superparamagnetic iron oxide nanoparticle (NB-SPION) suspension and supernatants. (A) Gel image: lane L, DNA ladder; lanes 1–3, polymerase chain reactions (PCR) with NB-SPIONs (1, 3, or 6 μg); lanes 4–6, PCRs with SPION-free supernatant (1, 3, or 6 μL); lane 7, PCR reactions without NB (negative water control); lane 8, PCR reactions with free NB (positive control); lane 9, 10 μg NB-SPIONs (nonamplification control). The 100-bp band has been indicated for reference. (B) Semiquantitative analysis of intensity peak size of 99 bp and 99 nt bands by ImageJ.
