Nanoparticles Size Evaluation by Frequency Domain Fluorescence Spectroscopy

Development of Rotational Correlation Time Measurement System for Brownian Particles

Abstract

Today's research puts a great emphasis on the bottom-up strategy, which consists of structuralization from the molecular scale, for the production of nanodevices smaller than 100nm. In this bottom-up method, nanoparticle is one of the important basic elements, where the functionality of the devices is heavily influenced by its size and shape. For the quality assurance of nanoparticles, nanoparticles size evaluation tool is required. In this study, nanoparticles size evaluation method based on frequency domain fluorescence spectroscopy is proposed. Measurement system for measuring rotational correlation time of Brownian particles is developed, and fundamental investigation is performed.
