- Additional information
- Gold Nanorods (GNRs), a subset of plasmonic nanoparticles, have unique optical properties that can be tailored for the biotechnology, electronics and biomedical industries due to their optical tunability and biological inertness, creating optical fibre sensors, exploiting their stable and easy surface chemistry. The algorithm developed in this paper using Bellman’s dynamic technique provides a unique approach for rapid determination of the GNRs’ aspect ratio distribution by theoretically fitting their longitudinal plasmon resonance obtained by UV-visible spectroscopy, offering a fast and potentially cost-effective solution to determine the quality of the synthesized GNRs specifically needed for applications for different, advanced sensor systems.
