Researchers work on proprietary particle coating and surface treatment technology to tailor the surface properties of the nanoparticles. By discreetly encapsulating individual particles with various chemical and physical processes, they are able to meet a customer’s performance requirements by controlling the particle size distribution, ensuring compatibility with the customer’s formulation, and including beneficial additives to control pH or rheology, to name a few. In most instances, it is beneficial to mediate the interface between the nanoparticle surface and the application matrix in which the nanoparticles are to be utilized. For example, for a naturally hydrophilic nanoparticle to be used effectively in non-polar media such as cosmetic oils, the surface of the particle may need to be rendered hydrophobic for uniform dispersion, compatibility, and performance. The proprietary chemistry and process technology used to prepare these dispersions ensures that the customers receive ready-to-use products in which the nanoparticles are stabilized at their primary particle size, with no secondary structure or agglomeration. The purpose to develop an optimized process is to impart a wide range of functionality to the particles, which not only ensures the success in the application but also provides the required flexibility in formulation with their nanoparticles. The effectiveness of these surface treatment and coating processes can be examined, verified and optimized with our precision instruments such as OCA, DCAT, ODG and T-100 on the produced particle samples in either dry powder or pre-dispersed format.
