Roomy cages built from DNA

Self-assembling cages are the largest standalone 3-D DNA structures yet, and could one day deliver drugs, or house tiny bioreactors or photonic devices

17-03-2014

Move over, nanotechnologists, and make room for the biggest of the small. Scientists at the Harvard's Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. The structures are some of the largest and most complex structures ever constructed solely from DNA, ...

Cells that sense light without seeing

11-02-2014

Researchers have found that the melanopsin pigment in the eye is potentially more sensitive to light than its more famous counterpart, rhodopsin, the pigment that allows for night vision. For more than two years, the staff of the Laboratory for Computational Photochemistry and Photobiology (LCPP) ...

Extraordinary sensors pushed to their boundaries

A new step is being taken in the development of ultra-stable sensors of small forces

13-01-2014

Last year, Tobias Kippenberg and his team from the Laboratory of Photonics and Quantum Measurements (LPQM1) presented a new-generation sensor capable of detecting very small forces with unprecedented efficiency. These devices, developed and fabricated at the Center of MicroNanofabrication (CMi) ...

Nanotube-based sensors can be implanted under the skin for a year

05-11-2013

Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous ...

A new approach to detecting food contamination enables real-time testing of food and processing plant equipment

22-10-2013

As anyone who has ever consumed bacteria-contaminated food and experienced "food poisoning" can tell you, it's a miserable experience. Yet it's an all-too-common one, with foodborne illnesses making 1 in 6 Americans -- or 48 million people -- sick each year. Of these people sickened, 128,000 end ...

Almost as sensitive as a dog's nose

New sensor for SERS Raman spectroscopy

02-09-2013

Scientists at ETH Zurich and the Lawrence Livermore National Laboratory (LLNL) in California have developed an innovative sensor for surface-enhanced Raman spectroscopy (SERS). Thanks to its unique surface properties at nanoscale, the method can be used to perform analyses that are more reliable, ...
