Innovative light therapy with nanophotosensitizers reaches deep tumors

Researchers have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer.

Go meta: New technique expands possibilities for molecular designers

Chemists have developed a broadly useful technique for building new drug molecules and other chemical products.

Electrons in slow motion

At the origin of the properties of high-temperature superconductors lies a phenomenon that is too fast to be observed experimentally with conventional methods. A team of scientists from different research centers has applied a sophisticated experimental technique, something like a moviola film-editing system, to slow down and analyze the structure of the process.

Ultrathin polymer insulators key to low-power soft electronics

Using an initiated chemical vapor deposition technique, researchers created an ultrathin polymeric insulating layer essential in realizing transistors with flexibility and low power consumption.

Quick, easy and early diagnosis with rare earth ions

A novel method makes it possible to measure oxygen in cells and other biological material with previously un-attainable precision. The method is based on rare earth compounds emitting colored light that vary in color with the amount of oxygen present in the sample. Because emissions are in the visible range of the spectrum, it will be possible to measure oxygen using the optical microscopes already present in most hospitals.

Toward Methuselah - long-living lighting devices

Scientists report important advances in the development of next generation lighting technologies.

The secret of wrinkling, folding, and creasing

New research provides a general formula for understanding how layered materials form different surface patterns.
