The activity of enzymes in industrial processes, laboratories, and living beings can be remotely controlled using light. This requires their immobilization on the surface of nanoparticles and irradiation with a laser. Near-infrared ...
KAIST researchers and their collaborators at home and abroad have successfully demonstrated a new methodology for direct near-field optical imaging of acoustic graphene plasmon fields. This strategy will provide a breakthrough ...
Since the early 2010s, ultrafast probing of materials at atomic-level resolution has been enabled by terahertz scanning tunneling microscopes (THz-STM). But these devices can't detect the dissipation of energy that happens ...
Visible and infrared light can carry more data than radio waves, but has always been confined to a hard-wired, fiber-optic cable. Working with Facebook's Connectivity Lab, a Duke research team has now made a major advance ...
Wearable sensing technology is an essential link in personalized medicine, where researchers must track multiple analytes inside the body simultaneously, to obtain a complete picture of human health. In a new report on Science ...
A team of researchers at the UCLA Samueli School of Engineering has demonstrated a new approach to an old problem: measuring spectra of light, also known as spectroscopy. By leveraging scalable, cost-effective nano-fabrication ...
Even the smallest molecule can tell a big story. For instance, observing a single molecule can throw light on underlying biological processes in the human body. In fact, molecular imaging procedures—which are noninvasive ...
In a study published in Advanced Materials, researchers from Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China of the Chinese Academy of Sciences, using an ...
Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. Experiments led by Hrvoje Petek, an R.K. Mellon professor in the Department of Physics ...
Bigger is not always better, but here's something that starts small and gets better as it gets bigger.
