There are various applications for LSPR in optics, photo catalysis and photovoltaic. Recently LSPR has been critically acclaimed as a biomolecule detection method. We investigate the unique plasmonic behavior of heterogeneous Al-Ag nanorod dimers. The LSPR behavior of this structure shows a significant Fano dip in its absorption cross section spectrum. This fano resonance can be tuned both in wavelength and amplitude by varying nanorod dimensions, separation distance and refractive index of the surrounding environment. We try to find the most sensitive configuration within these variables. The Al-Ag nanorod plasmonic structure shows a high sensitivity of 295~297.5 to the surrounding environment. This proves it as an excellent applicant for sensing and detecting biomarkers of different diseases and thus accelerating medical diagnostics technology.69 pagesenBRAC University thesis is protected by copyright.
