An artificial system using a DNA-laced hydrogel can receive a chemical signal and release the appropriate protein, according to Penn State researchers. Further stimulation by the chemical signal continues to trigger a response.

A hydrogel is a network of polymer chains that attract water and can be used to simulate biological tissue.

Many systems in cells and in the human body are set up with a signal and response pathway. One of the best known is that of glucose, a small sugar that triggers the release of insulin.

The properties of materials can behave in funny ways. Tweak one aspect to make a device smaller or less leaky, for example, and something else might change in an undesirable way, so that engineers play a game of balancing one characteristic against another. Now a team of Penn State electrical engineers have a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a near zero thickness and weight.

One of the latest ventures to come out of Penn State, Persea Naturals, began with an unintended discovery. Gregory R. Ziegler, professor of food science in the College of Agricultural Sciences, was extracting starch from avocado pits when he noticed something interesting. When avocado pits are pulverized, an enzymatic reaction produces a bright orange color. After extracting the starch, Ziegler just couldn’t get the color to wash away.

That constant change is what motivates materials scientist Lauren Zarzar in her research.

“The world around us is always changing—materials are constantly being exposed to different external pressures, external stimuli,” says Zarzar, assistant professor of materials science and engineering and assistant professor of chemistry. “Many materials we use are static in their properties and functions, but I’m interested in designing materials that respond to changes in the environment.”

All ferroelectric materials possess a property known as piezoelectricity in which an applied mechanical force can generate an electrical current and an applied electrical field can elicit a mechanical response. Ferroelectric materials are used in a wide variety of industrial applications, from ultrasound and sonar to capacitors, transducers, vibration sensors and ultrasensitive infrared cameras. Now, an international team of scientists led by Penn State may have solved the 30-year-old riddle of why certain ferroelectric crystals exhibit extremely strong piezoelectric responses.
