Advanced Photonics Journal of Applied Remote Sensing Development of a novel biosensor for Creatine Kinase (CK-MB) using Surface Plasmon Resonance (SPR) Publication year: 2021 Authors: André L.Ferreira a,1, Lucas F.de Lima b,1, Ariana S.Moraes a,1, Rafael J.G.Rubira c,1, Carlos J.L.Constantino c, Fabio L.Leite a, Adriana O.Delgado-Silva a, Marystela Ferreira a Surface plasmon resonance is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light. SPR is the basis of many standard tools for measuring adsorption of material onto planar metal surfaces or onto the surface of metal nanoparticles. It is the fundamental principle behind many color-based biosensor applications, different lab-on-a-chip sensors and diatom photosynthesis.

A crucial aspect for these applications is how the surface plasmon resonance of metal nanoparticles is modified after assembly with graphene. Here, we used the discrete dipole approximation method to study the surface plasmon resonance of silver and gold nanoparticles in the proximity of a graphene flake or embedded in graphene structures.

The available data lead us to two different equations, one for silver and one for gold nanoparticles which correlate their size, concentration and wave-length. For gold nanoparticles, the equation came out to be 0.012log 0.36 196 10 324 • Nanoparticles can be used as labels to create DNA microarrays for specific detection of target strands. • This can allow for cheap, quick imaging using simple optical methods. • This method can be extended to take advantage of the changes in plasmon resonance by particle aggregation.

In fact, plasmons are highly responsive to a multitude of factors, either intrinsic to the Au NPs or from the environment, and recently the need emerged for the correction of standard The basis for the effect is the plasmon resonance of the free electrons in the metal nanoparticle, which can be understood by studying the polarizability (the ease with which charges, such as the conduction electrons on the metal nanoparticle surface, undergo charge distribution and form partial dipoles).
