Measurement Techniques for Electrostatic Charged Microspheres

Co-founders of Cospheric, developed real-time reliable technique for measuring electrostatic charge on microspheres. The technique involves creating a monolayer of microspheres contained in microstructure with each sphere being separated from its neighbors. This technique allows precise measurement of electrostatic charge of a large quantity of microspheres without allowing sphere-sphere interactions.

Chitosan microspheres prepared by spray drying

Spray drying has been used in the production of fine powders from emulsions for many years, but it is not a process in which most people associate the production of microspheres. This journal article shows how the authors were able to produce highly spherical microspheres in the 1-10um range by controlling the levels of Chitosan and crosslinking agents…
