Human pathogens have molecular fingerprints that are difficult to distinguish. To better detect these pathogens, sensors in diagnostic tools need to manipulate light on a nanoscale. To manufacture these light-manipulation devices without damaging the sensors, Purdue University engineers have integrated light-manipulation devices onto peelable films that can stick to any surface.
How do you know a cell has a fever? Take its temperature. That’s now possible thanks to research by Rice University scientists who used the light-emitting properties of particular molecules to create a fluorescent nano-thermometer.

A physicist at the University of Texas at Dallas has teamed with Texas Instruments Inc. to design a better way for electronics to convert waste heat into reusable energy. The collaborative project has demonstrated that silicon’s ability to harvest energy from heat can be greatly increased while remaining mass-producible.

Researchers at the University of Illinois and the Missouri University of Science and Technology have modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust. The technique is based on a field of physics called plasmonics that studies how optical light or optical electromagnetic waves, interact with nanoscale structures.

A research team at Harvard's Wyss Institute for Biologically Inspired Engineering and the Massachusetts Institute of Technology demonstrates the use of CRISPR as a control element in a new type of stimuli-responsive "smart" materials. Upon activation by DNA stimuli, a CRISPR-Cas enzyme enables smart materials to release fluorescent dyes and active enzymes, deploy encapsulated nanoparticles and live cells, or regulate electric circuits.

Most pharmaceuticals must either be ingested or injected into the body to do their work, and it takes some time for them to reach their intended targets. Also, these pharmaceuticals tend to spread out to other areas of the body. Now, researchers at MIT and elsewhere have developed a system to deliver medical treatments that can be released at precise times, minimally invasively, and that ultimately could also deliver those drugs to specifically targeted areas such as a specific group of neurons in the brain.
