GE&R is pioneering the development of patented nano-sized chemical release capsules. We use novel nano-material processing techniques to load nanoparticles with various chemical payloads and coat the particles to form capsules.

Applications:  polishing or chemical mechanical planarization (CMP) slurries, targeted chemical delivery, bio-applications, other applications? Let GE&R help develop a custom solution.   Contact us >>

Porous Particle – Various base particles possible (silica, alumina, etc.)

Chemical Payload – Various chemical payloads possible (complexing agents, salts, oxidizers, etc.)

Polymer Coating – the polymer coating can be tailored for different release mechanisms (i.e. mechanical or shearing abrasion, timed release in certain solvents, temperature release, etc. )
