There is a rising interest in plasmonic nanostructures in labs around the world. The interesting optical properties of these materials are finding applications in biomedicine, sensing, and solar energy harvesting. The nanoDDSCAT project is aimed at equipping the research community with a versatile easy-to-use tool that will allow the understanding and design of optically interesting plasmonic nanostructures. nanoDDSCAT is a collaborative effort between the Jain lab (supported by a NSF CAREER award) and the NSF-funded nanoBIO node at UIUC.

About the nanoDDSCAT project

The nanoDDSCAT and nanoDDSCAT+ tools are now freely available via nanoHUB.org. The tools, based on the PhD thesis of PI Jain, utilizes the open-source implementation of the discrete dipole approximation method developed by B. T. Draine and P.J. Flatau of Princeton University. The tools have a user-friendly GUI interface that will allow custom design of plasmonic nanostructures of arbitrary complexity. Research-grade simulation and visualization of absorption and scattering spectra and near-fields are possible. Training on the tool are possible via the nanoDDSCAT manual, videos hosted on the nanoBIO node YouTube channel, & the BioNanotechnology Summer Institute. We have 600+ users worldwide and research papers/proceedings have resulted from the application of these tools by our user-base:
