A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios.
A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene.
A soft, stick-on patch collects, analyzes and wirelessly transmits a variety of health metrics from the body to a smartphone.
SWIFT magnetic resonance tool assures removal of nanoparticles from rewarmed samples.
A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasized cancer cells in the blood stream and then killing these cells, according to a new research study.
To improve viewing pleasure, companies have developed television—and tablet screens—that include quantum dots to enhance brightness and color. Some quantum dots are made with potentially harmful metals, which could leach into the environment when the device is discarded. But other TVs made with less hazardous nanomaterials require more energy to make. Today, researchers report preliminary results suggesting that under simulated landfill conditions, quantum dots can leach out of devices. But because this happens in such tiny amounts, the team says that in the grand scheme of things, it might make sense to use the more toxic quantum dots that are made with a more eco-friendly process.
A new data analysis technique, moving subtrajectory analysis, defines the dynamics and kinetics of key molecules in the immune response to an infection. These biophysical descriptions are expected to clarify the TCR microcluster, an essential assembly for a T cell to initiate its attack on a pathogen.
Synthetic nanomotors and DNA walkers, which mimic a cell’s transportation system, are intricately designed systems that draw chemical energy from the environment and convert it into mechanical motion. Using such DNA walkers as signal amplifier for nucleic acids detection has only recently been reported. Researchers now report that they converted a DNA walker into a linear fluorescence signal amplifier on a rectangle DNA origami that can improve the detection of target molecules such as nucleic acids.
Scientists report they are on the cusp of using silk to develop a more sensitive and flexible generation of these multi-purpose devices that monitor a slew of body functions in real time.
Researchers describe how wrapping biological tissue in a nanosheet of a particular organic material results in high-quality microscopy images.
