SpectraCube LSPR system:

a complete spectrophotometer optimized for plasmonic nanoparticles applications. Its design based on imaging spectroscopy has the advantage to allow both conventional single-channel analysis for sample characterization and dual-channel mode for real time differential detection using vertical or horizontal configuration with tandem cuvettes. The device is paired with an analytics software designed to precisely detect and follow plasmonic peak position (up to 0.01 nm). The system is ideal for LSPR applications including nanoparticles size and composition characterization, biosensing, and real-time monitoring of nanoparticles functionalization.
