Method of Encapsulating a Fluid Between a Polymer and a Substrate for Microfluidics
Published Monday, July 14, 2014Background:Microfluidic devices are filled with liquid using ports and tubing, since they are typically open devices. However, for closed systems the tubing is cumbersome and it needs to be closed, for example mechanically (using clamps, plugs) or with a sealant. These protrusions can interfere with the performance of the device,...

Methods for prediction of subject-specific hemodynamic response to vasopressors
Published Sunday, June 29, 2014BackgroundVasopressors are medications that raise blood pressure in a patient, which helps increase blood flow to peripheral tissues. Vasopressors are commonly used to treat patients who have a body wide reduction in blood circulation. Currently, vasopressors are administered manually by clinicians, who typically adjust dosage iteratively...
