摘要: In this paper, we study the interaction of a small dye molecule, namely, methylene blue (MB) with graphene surfaces using surface plasmon resonance (SPR). We show that by utilizing all parameters SPR angular dip and exploiting fact MB absorbs light at operating wavelength, it is possible to detect binding molecules would otherwise not give significant signal. The unmodified found be stronger than for gold. By studying modified surfaces, demonstrate electrostatic effects play dominant role in on graphene. Furthermore, following kinetics various concentrations allows us estimate apparent equilibrium rate constants
