Enzyme Molecules as Nanomotors
Samudra Sengupta, Krishna K. Dey, H. S. Muddana, Tristan Tabouillot, Michael E. Ibele, Peter J. Butler, and Ayusman Sen (Penn State)
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 that movement is a general consequence of enzymatic reactions. This movement depends on the concentration of the enzyme's substrate (the fuel for its reaction) and causes individual enzyme molecules t

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
Suo and Whitesides
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
range, from a gentle touch of a finger to strains over 500%. The new ionic skin
has attributes required for biocompatibility in medical devices and

Electrically collapsible hydrogels with enhanced mechanical toughness
Clarke, Mooney, Parker, Suo, and Vlassak
A
Harvard MRSEC team led by Clarke, Mooney, Parker, Suo, and Vlassak has developed new hydrogels
that are both electrically responsive and mechanically tough. Poly(acrylic
acid) hydrogels can be made to be macroporous and therefore capable of rapid

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
structures is affected by their size and shape and may significantly differ
depending on the properties of the bulk material. Nebraska MRSEC researchers
