Flow-Enhanced Vesicle Deformation in the Four-roll Mill

Research

This project leverages ongoing research on the dynamics of DNA and vescicles within CPIMA.Â’  We have developed a novel microfluidic four-roll mill that allows all flow types (from extension to shear to rotation) to be accessed and have previously used it to examine DNA tumbling in mixed flows and, most recently, to study vesicle dynamics.

DNA-tethered Membrane Formation From Giant Unilamellar Vesicles

Research

We have developed two strategies forÂ’  preparing tethered lipid bilayer membrane patches on solid surfaces by DNA hybridization.Â’  In the first strategy, single-stranded

Colloidosome Assemblies.

Research

Rotello developed a very rapid and convenient method for fabricating microspheres with walls made of nanoparticles, known as colloidosomes. In this method alkyne and azide functionalized iron oxide nanoparticles are co-assembled at the water-in oil-interface and covalently linked using “click” chemistry under ambient conditions to create magnetic

Macroscopic Addressable Arrays of Block Copolymers With Areal Densities of 10 Terabit/inch2 and Beyond

Research

A collaboration between researchers funded by the DOE and NSF-supported MRSEC and CHM at UC Berkeley and UMASS Amherst has led to a breakthrough in the areal density of templates derived from block copolymers (BCPs) having orientational registry over macroscopic distances. The facets on a reconstructed single crystal surface, like

Fundamental MIT MRSEC research enables life-saving technology

Technology based on fundamental studies carried out within our MRSEC is now saving lives at hospitals across the country: over 175 novel endoscopic surgical procedures per week are being carried out across 250 medical facilities in the U. S. using high-power laser radiation delivered by OmniGuide photonic fibers.
