Dear Hong, I think we can make a master for you in silicon if you are interested. Please feel free to contact me.

The channel size maybe 100micro width, 20-50 micro depth and 1cm length. We don't want to fabrication master by ourself. Does anyone know where can we buy some? Any proper material of master suitable for PDMS channel fabrication is fine. > Thank you. > Hong > _______________________________________________ > MEMS-talk@memsnet.org mailing list: to unsubscribe or change your list > options, visit http://mail.mems-exchange.org/mailman/listinfo/mems-talk > Hosted by the MEMS Exchange, providers of MEMS processing services. > Visit us at http://www.memsnet.org/
