An international team of researchers developed a novel technique to produce precise, high-performing biometric sensors — ScienceDaily

Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.

Led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, the team published their results in ACS Applied Materials & Interfaces.

“In this article, we report a simple yet universally applicable fabrication technique with the use of a novel sintering aid layer to enable direct printing for on-body sensors,” said first author Ling Zhang, a researcher in the Harbin Institute of Technology in China and in Cheng’s laboratory.

Cheng and his colleagues previously developed flexible printed circuit boards for use in wearable sensors, but printing directly on skin has been hindered by

Technique permits convenient, precise optical imaging of individual proteins — ScienceDaily

Often considered the workhorses of the body, proteins are among the most important biomolecules critical to life processes. They provide structural foundation for cells and tissues and perform a dizzying array of tasks, from metabolizing energy and helping cells communicate with one another to defending the body from pathogens and guiding cell division and growth.

Because protein dysfunction is implicated in so many serious diseases, proteins are the primary targets for most therapeutic drugs.

In a new study, Shaopeng Wang and his colleagues describe a method for examining proteins in keen detail. To do this, his group makes clever use of a phenomenon known as surface plasmon resonance (SPR), incorporating it into an innovative type of microscope.

While SPR has been a powerful technique for investigating the world of the very small, including the interactions of bacteria and viruses, the study marks the first occasion when SPR has successfully been
