  • Wavelength dispersive microscope spectrofluorometer for characterizing multiple particles simultaneously
    Patent number: 10267734
    Abstract: Provided are inexpensive devices and methods for obtaining emission or scattering spectra of multiple particles simultaneously and for characterizing the particles based on their emission or scattering spectra. The disclosed devices and methods are useful for analyzing multiple particles to determine one or more characteristics of the particles, such as size, type, elastic scattering, fluorescence and/or Raman characteristics, for distinguishing between biological and non-biological particles, and for biomedical assaying applications. Laboratory or research grade spectroscopic devices are described. Smartphone-based spectroscopic devices are also described, where various components of a smartphone are used for data collection and analysis purposes.
