abstract: The study of materials with nanoscale dimensions has gained wide spread research interest as these exhibit novel properties that can be used to manipulation of light for applications ranging from biosensing to optoelectronics. Metallic nanostructures coupled with light exhibit a collective oscillation of conduction band electrons leading an optical feature known as surface plasmon resonance (SPR). Quantum confinement effects in semiconductor nanoparticles allows the control over optical and electronic properties by changing size and shape of the nanoparticle. In order to fully realize the full potential of these interesting properties in nanoscale materials, this dissertation explores on fundamentals of these light matter interactions in nanoscale. The first work in this dissertation investigates on a novel plasmonic array that can be integrated into microfluidic channels to monitor real time biological interactions. The second work explores on coupling between one dimensional chains of plasmonic nanoparticles which leads delocalized surface plasmon feature which is highly sensitive local dielectric changes. The third study uses SPR to detect and quantify the interaction between the HIV capsid proteins and lipid bilayer films with the goal of establishing a potential drug target for HIV infection. The last study investigates on a general strategy to eliminate Fermi level pinning in semiconductor quantum dots using a thin film of alumina which may enhance the photoconversion efficiency in Schottky junction solar cells. The topics covered here should enable an insight into the fundamentals of light matter interactions in nanostructures which may facilitate their applications in sensing and photovoltaics.
