Researchers have developed a method, described in APL Bioengineering, that uses machine learning to determine whether a single cell is cancerous by detecting its pH. Their approach can discriminate cells originating from normal tissues from cells originating from cancerous tissues, as well as among different types of cancer, while keeping the cells alive. The method relies on treating the cells with bromothymol blue, a pH-sensitive dye that changes color depending on acidity.
By analysing minute vibrations on common items caused by sound waves, a potential attacker can use a robot vacuum cleaner to retrieve audio data and capture private and sensitive information
A shirt that monitors your blood pressure or a pair of socks that can keep track of your cholesterol levels might be just a few years away from becoming reality. In Applied Physics Reviews, researchers examine the use of microfibers and nanofibers as wearable monitors that could keep track of a patient’s vital signs. The microfiber- and nanofiber-based technology addresses growing concerns in the medical community about monitoring chronic illnesses as the population ages.
Using face masks to help slow the spread of COVID-19 has been widely recommended by health professionals. This has triggered studies of the materials, design, and other issues affecting the way face masks work. In Physics of Fluids, investigators looked at research on face masks and their use and summarized what we know about the way they filter or block the virus. They also summarize design issues that still need to be addressed.
Many compact systems using mid-infrared technology continue to face compatibility issues when integrating with conventional electronics. Black phosphorus has garnered attention for overcoming these challenges thanks to a wide variety of uses in photonic circuits. Research published in Applied Physics Reviews highlights the material’s potential for emerging devices ranging from medical imaging to environment monitoring, assessing progress in different components of the chips, from light detection to laser emission.
