Novel label-free microscopy enables dynamic, high-resolution imaging of cell interactions

09-Dec-2016

Researchers from the University of Illinois at Urbana-Champaign have invented a novel live-cell imaging method that could someday help biologists better understand how stem cells transform into specialized cells and how diseases like cancer spread. The Photonic Crystal Enhanced Microscope (PCEM) ...

Shining a light on damage within polymers

19-Aug-2016

When it comes to even the most advanced materials, the adage "if it does not bend, it breaks" is often true. But before that final snap, most materials experience microscopic damage that could be fixed -- but only if you know it's there. In a study researchers introduce a new technique that ...

Watching 'jumping genes' in action

Real-time observation of transposon activity in living cells

16-Jun-2016

"Jumping genes" are ubiquitous. Every domain of life hosts these sequences of DNA that can "jump" from one position to another along a chromosome; in fact, nearly half the human genome is made up of jumping genes. Depending on their specific excision and insertion points, jumping genes can ...

3-D micro X-ray images help answer questions about fried foods' internal structure

29-Feb-2016

What happens to food and its microstructure when it is fried is a complicated process, both scientifically and mathematically speaking. While consumers want a product that is crispy and tasty, food scientists seek to get a closer glimpse into what exactly is going on inside the food during frying ...

Researchers combine disciplines, computational programs to determine atomic structure

27-Aug-2015

A team from the University of Illinois at Urbana-Champaign and Indiana University combined two techniques to determine the structure of cyanostar, a new abiological molecule that captures unwanted negative ions in solutions. When Semin Lee, a chemist and Beckman Institute postdoctoral fellow at ...

'Nanocamera' takes pictures at distances smaller than light's own wavelength

How is it possible to record optically encoded information for distances smaller than the wavelength of light?

22-Jul-2014

Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances ...

Illinois researchers combine weak chemical forces to strengthen novel imaging technology

A new nanoparticle design, inspired by cell membranes, has led to clearer MRI images and paved the way for better diagnostic tools

26-May-2014

When University of Illinois Associate Professor of Chemical and Biomolecular Engineering Hyunjoon Kong, graduate student Cartney Smith, and colleagues set out to improve MR imaging (MRI), they turned current contrast agent technology on its head —or rather, they turned it inside out. The new ...

Potent, puzzling and (now less) toxic: How antifungal drug works

17-Apr-2014

Scientists have solved a decades-old medical mystery – and in the process have found a potentially less toxic way to fight invasive fungal infections, which kill about 1.5 million people a year. The researchers say they now understand the mechanism of action of amphotericin, an antifungal drug ...

New insights into ribosome self-assembly

14-Feb-2014

Ribosomes, the cellular machines that build proteins, are themselves made up of dozens of proteins and a few looping strands of RNA. A new study, reported in the journal Nature, offers new clues about how the ribosome, the master assembler of proteins, also assembles itself. "The ribosome has ...

CARS microscopy on its way to clinical translation

13-Jan-2014

Stained histopathology is currently the gold standard for disease diagnosis but remains a subjective practice on processed tissue, taking from hours to days. More quantitative and rapid analysis could be provided by near-infrared Raman microspectroscopy, an attractive alternative which offers a ...
