Program Highlights for year 2014

Enzyme Molecules as Nanomotors

MRSEC researchers have recently discovered that enzymes - molecules that catalyze chemical reactions in cells - move during the reaction.  Although this property is well known for motor proteins, it has not been previously known t

Engineering Cellular Response Using Nanopatterned Bulk Metallic Glass (BMG)

Research

Biomaterials implanted in the body evoke a “Foreign body response” which results in encapsulation of the material in a collagen-rich protein capsule. Fibroblast cells, which produce collagen, mediate this process that leads to biomaterial rejection / device failure in vivo. Surface nanotopography of BMGs can be used to engineer fibroblast-material interactions.

Sensor Skin - A platform for highly stretchable, biocompatible, transparent sensors

Research

In work reported in Science (August 20, 2013) a Harvard MRSEC team led by Suo and Whitesides developed a transparent “ionic skin,” a sensor skin using ionic conductors. It senses signals with high stability and wide dynamic

Magnetic Domain Structure of Cobalt Nanospirals

Research

Nanoscale three-dimensional (3D) structures are building blocks for the fabrication of miniature switching devices and can be used as functional units in nanorobotics. The functionality of the 3D
