(A) UV-Vis for 30 nm gold nanoparticles synthesized with sodium citrate indicated in our tests that AuNPs exhibited a strong resonance peak at 525 nm (λmax). (B) SPR band of nanoparticles stabilized with sodium citrate in the absence and presence of aptamer. A shift of 2–3 nm suggests a relatively small change in the nanoparticle environment, which suggests that the aptamer is interacting with AuNPs. These observations should be validated with larger-scale clinical and field testing.
