Detecting Evidence of Lung Cancer in Exhaled Breath
American Chemical Society (ACS)

Exhaled breath contains chemical clues to what’s going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses — and improve patients’ prospects. In a study in ACS Sensors, researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer. November is Lung Cancer Awareness Month.

Turning Plants Into Workout Supplement Bio-Factories
American Chemical Society (ACS)

It’s important to eat your veggies, but some essential vitamins and nutrients can only be found in animals, including certain amino acids and peptides. But, in a proof-of-concept study published in ACS’ Journal of Agricultural and Food Chemistry, researchers developed a method to produce creatine, carnosine and taurine — all animal-based nutrients and common workout supplements — right inside a plant. The system allows for different synthetic modules to be easily stacked together to boost production.

Spinning Artificial Spider Silk Into Next-Generation Medical Materials
American Chemical Society (ACS)

Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one consists of proteins and heals wounds instead of haunting hallways. The artificial silk is strong enough to be woven into bandages that helped treat joint injuries and skin lesions in mice.

Scientists use magnetic nanotech to safely rewarm frozen tissues for transplant
American Chemical Society (ACS)

Looking to extend the viability of human tissues, researchers report in ACS’ Nano Letters their efforts to facilitate completely freezing, rather than cooling and then thawing, potentially life-saving organs for transplant. They demonstrate a magnetic nanoparticle’s successful rewarming of animal tissues.

Getting the stink out of smoke-tainted wine
American Chemical Society (ACS)

Wildfires can damage crops, even if flames come nowhere near the plants. One outcome can be an unpleasant flavor and smell of wine that is made from grapes exposed to smoke. But researchers report in ACS’ Journal of Agricultural and Food Chemistry that they have developed a way to lessen this smoke taint to improve the palatability of the wine.
