The sensor has a very simple design: gold nanoparticles resting in the surface of a grafted P2VP film. Changes in the gold nanoparticles' position causes changes in the plasmon coupling mode. This is detected by means of a maximum absorbance shift.1226-1230engbiopolymerizationbiosensorsnanotechnologyplasmonic platformspolymerizationArtigo10.1002/chem.201304148WOS:000336431100004Acesso restrito7781282422851911
