Manufacturing microspheres to customer's specific color requirements.


specializes in developing and manufacturing microspheres 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.


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.

Cospheric has in-house capabilities to develop and manufacture microspheres in custom color formulations for cosmetic, industrial or medical applications. Solid polyethylene microspheres 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 microspheres visible in any point in the process. Numerous applications in diagnostics, troubleshooting, process flow, medical research, biotechnology, quality control and other industries.
