Most events on this list can be tied to a specific page somewhere on the internet.  List entries contain links to such pages through the "Details".   Occasionally events have no such page or the information on it is inadequate.  In such cases I attempt to cobble together a details page myself.



*Rapid prototyping of thermoplastics*

The explosion of lab-on-a-chip designs in academics circa 2000 was due to the development of soft lithography based on the elastomer PDMS. However, few commercial applications are produced in PDMS. Instead, most commercial microfluidics are produced in thermoplastics for reasons of lower manufacturing costs, improved solvent resistance and ease of surface treatments. Academic labs have been slow to adopt thermoplastics because of challenges in making masters, in creating replicas, in sealing devices and in surface treatment.

We report a method that solves all the above mentioned problems and is practical, inexpensive, reliable and works for a wide variety of designs. It has allowed us to manufacture chips in the thermoplastic COC faster, better and cheaper than with PDMS and positions academic labs one step closer to commercialization.
