Fluorescent Particles

Fluorescence occurs when a molecule absorbs energy in the form of light and then immediately releases this energy again in the form of light.

Excitation wavelength - characteristic wavelength that molecule absorbs

Emission wavelength - characteristic wavelength that molecule emits

Fluorescent Particles are round spherical particles that emit bright colors when illuminated by UV light. Fluorescent Particles offer extra sensitivity and detectability for analytical methods.

Abvigen's fluorescent polymer microspheres are available in many particle sizes, colors, densities, and excitation and emission wavelengths, can be stored at room temperature or dispersed in aqueous media without degrading their fluorescent properties. Abvigen offers a series of fluorescent particles, commonly used in biological field for tracing, cell labeling, in vivo imaging, drug discovery research and calibration of flow cytometry, among other applications.
