Figure 1. Riboflavin emission spectra as a function of added nanoparticle concentration for various nanoparticles.

Figure 1.

a. 10nm gold nanospheres. b. SWNTs dispersed by (AT)15. c. graphene dispersed by polyvinylpyrrolidone (PVP). d. Probe fluorescence at different concentrations in three different systems: reference, free polymer solution (single strand DNA), and free polymer + SWNT solution. In case of ss(GT)15, a NaCl buffered solution was chosen as the solvent background.
