Abstract
The process and product are disclosed for mounting free-flowing particles, which employ a support having a support surface with an array of tacky areas which have a size and bonding strength suitable for adhesion of either one or two of said particles. In the process the particles flow across the support surface to allow particles to contact the tacky areas and adhere thereto. An array of mounted particles may thus be provided which has at least 50% singly or doubly mounted particles.
