Hello, all, I'm trying to find polymer asymmetric (either shape or half0color coated, etc,) microbeads of 10-15 micrometer diameter. It's for DEP rotation, therefore metal coating is not a good idea. Any suggestion? thanks, Hong _______________________________________________ Hosted by the MEMS and Nanotechnology Exchange, the country's leading provider of MEMS and Nanotechnology design and fabrication services.
