Fluorescent Polyethylene Spheres

Fluorescent polyethylene microspheres emit bright colors and become highly visible when illuminated by UV light. Cospheric's fluorescent polyethylene microspheres are available in many particle sizes, colors, densities, and excitation and emission wavelength. Unlike other fluorescent particles on the market, Cospheric's microspheres can be stored at room temperature or dispersed in aqueous media without degrading their fluorescent properties.

Custom colors, particle sizes, densities can be manufactured by request. Contact us to discuss your unique requirements for fluorescent microspheres. More information on fluorescent microspheres and their applications.

Cospheric specializes in manufacturing and developing microspheres, spheres, microbeads and particles to customer's specific color requirements. Color can be matched as a color of monolayer of spheres or bulk color. Desired custom color microspheres can be manufactured with UV fluorescing capability.

As an example, Cospheric color-matched customer's flesh tone sample to create microspheres that blend into the surface of the skin or flesh and become invisible to the observer under daylight illumination (see Figure 1). Those same flesh-color microspheres have capability to fluoresce bright yellow-green at 365nm UV light (see Figure 2).

Figure 1: Flesh-tone microspheres developed to blend into the skin and not be visible to an observer. Notice how the microspheres blend in perfectly to match the background of skin sample in daylight. Color-Matched Skin Color Flesh Tone Microspheres Figure 2: Flesh-tone microspheres invisible to observer in daylight, become highly visible in yellow-green fluorescent color under 365nm UV light or black light, clearly distinguishing the microspheres from the background. Black Light - UV Light - Custom color-changing particles
Cospheric has in-house capabilities to develop and manufacture microspheres in custom color formulations for cosmetic, industrial or medical applications. Solid polyethylene microspheres, spheres, beads and microparticles can be developed to blend into background of any color. This functionality enables scientists and engineers to conduct controlled blind tests and experiments and make particles visible in any point in the process. Numerous applications in diagnostics, troubleshooting, process flow, medical research, biotechnology, quality control and other industries.
