Nanoparticle-based Optical Components and Coatings (NOCC)
Abstract
This program will explore fabricating optical components (microscale mirrors) and coatings (gradient-index) using DNA-nanoparticle (DNA-NP) superlattices. While the fundamental science of making these complex assemblies in solution is well-understood, and we~ve made progress under our current effort at understanding their assembly on surfaces, the optical properties of the structures, and their relation to assembly conditions, remain largely unknown. Optical spectra of various nanoparticle assemblies will be taken and analyzed with corresponding microscopy images. Comprehensive finite-difference time-domain (FDTD) simulations will be done to model the effect of variability of nanoparticle size within a sample, as well as the to determine the proper way to model the refractive index of silicized DNA. Experimental optical spectra will be compared to simulated spectra and the model will be adjusted until a proper numerical modeling approach is obtained. This will be of great interest to the general nanophotonic and nanoparticle assembly community.
