The colloidal coating determines the physical and chemical properties of the colloidal particles, determines the interaction of the colloidal particles with various environmental systems, and thus determines their overall behavior and fate in the application process. Therefore, coating materials are important, especially for colloidal particle systems for biomedical applications. Alfa Chemistry has studied the various obstacles encountered in the effective application of colloidal particles, and can design different coating solutions for colloidal particles to meet specific application needs.

Research and Practice of Colloidal Coatings

With advances in organic and polymer chemistry, a number of customizable coating techniques can be applied to colloidal particles. No matter which coating material is used, the most basic requirement is to ensure the colloidal stability of the colloidal particles throughout the path from production to storage to application. The sterically stable colloidal particles can be widely used in water remediation, drug delivery, contrast agents and other fields.
