Microfluidic techniques for the study of self-assembly of soft materials
by Aguade Cabanas, Rafael, Ph.D., Brandeis University, 2014, 137; 3611603
Abstract (Summary)

This research is an approach to the study of soft condensed matter where the use of new microfluidic technology plays a central role. Often, in the study of soft matter, the sample volumes are very small, of the order of nanoliters. Therefore to quantitatively measure the equilibrium or non-equilibrium phase behavior requires microfluidics. Presented here are (1) a new way of producing aqueous drops of order 1 nl volume, in oil, (2) a new fabrication protocol to make microfluidic devices out of epoxy glue, and (3) a new microfluidic flow cell to study colloidal self-assembly. Also presented here is a new kind of colloidal particle, consisting of single strands of DNA linked to the surface of fd virus. This new particle may serve as a liquid crystalline colloid with a temperature dependent tunable potential. The fabrication process is the first step in the study of the self-assembly of rod-like particles with a temperature dependent potential.
