Flexible neck in cell-receptor DC-SIGN targets more pathogens

New findings from a research team led by University of Illinois chemist Deborah Leckband show that flexibility in the region near the binding sites of DC-SIGN plays a significant role in pathogen targeting and binding.

First acoustic metamaterial 'superlens' created by U. of I. researchers

A team of researchers at the University of Illinois has created the world’s first acoustic “superlens,” an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology.

Unlike rubber bands, molecular bonds may not break faster when pulled

Research led by chemistry professor Roman Boulatov contradicts the intuitive notion that molecules – like rubber bands – break faster when pulled.

Scientists break light modulation speed record – twice

Researchers have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a light-emitting diode.

Faster protein folding achieved through nanosecond pressure jump

A new method to induce protein folding by taking the pressure off of proteins is up to 100 times faster than previous methods, and could help guide more accurate computer simulations for how complex proteins fold, according to research by a team of University of Illinois scientists.

Evidence of macroscopic quantum tunneling detected in nanowires

Researchers at Illinois have demonstrated that an entire collection of superconducting electrons in an ultrathin superconducting wire is able to “tunnel” as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.

Synthetic catalyst mimics nature's 'hydrogen economy'

By creating a model of the active site found in a naturally occurring enzyme, chemists at the University of Illinois have described a catalyst that acts like nature’s most pervasive hydrogen processor.

See the force: Mechanical stress leads to self-sensing in solid polymers

Parachute cords, climbing ropes, and smart coatings for bridges that change color when overstressed are several possible uses for force-sensitive polymers being developed by researchers at the University of Illinois.

Nanoneedle is small in size, but huge in applications

Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In addition to ferrying tiny amounts of cargo, the nanoneedle can also be used as an electrochemical probe and as an optical biosensor.
