Abstract
Embodiments of the invention provide fluidic devices such as, but not limited to, microfluidic chips, with one or more freeze thaw valves (FTVs) employing one or more ice-nucleating agents (INAs), that can reliably operate to freeze at relatively higher temperatures and/or at faster rates than conventional microfluidic devices with FTV systems.
