About Microspheres

Microspheres are tiny spherical particles with diameters ranging from a few micrometers to a few millimeters. These versatile particles have a wide range of applications in a variety of industries, including pharmaceuticals, biotechnology, materials science, and more. By precisely controlling the composition, size, and surface properties of microspheres, scientists and engineers can unlock their unique properties and capitalize on their potential in a wide range of applications.

Our Microsphere Services

Protheragen-ING focuses on the development of microspheres. We have conducted in-depth studies and comparisons of synthetic materials, microsphere particle sizes, types of surface groups and their densities, encapsulation methods and efficiencies, microsphere modifications, coupling methods, etc., and have successfully developed a wide range of microsphere particles, which have gained favorable evaluations from both the market and our customers.

We provide a full set of microsphere design and development services to meet the diverse needs of our customers.
