A project led by University of Queensland Ph.D. student Javeria Bashir has produced specially crafted gold nanoparticles that can highlight cancer markers in samples like urine, saliva, or blood. Bashir said she hoped to ...
In a breakthrough for next-generation technologies, scientists have learned how to precisely control the behavior of tiny waves of light and electrons, paving the way for faster communications and quantum devices.
Half of the sun's radiant energy falls outside of the visible spectrum. On a cold day, this extra infrared light provides additional warmth to residential and commercial buildings. On a warm day, it leads to unwanted heating ...
A new breakthrough in the field of physics led by doctoral student Yueming Yan could allow for the creation of small, thin, low-power optical devices to be used in both medical imaging and environmental sensing.
Researchers from the Indian Institute of Science Education and Research (IISER) Pune and the Indian Institute of Technology-Bombay have developed an innovative, cost-effective method to produce high-quality metal nanoparticles, ...
Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark Brongersma, a professor of materials science and engineering at Stanford University, and doctoral candidate ...
A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality.
Traditional medical tests often require clinical samples to be sent off-site for analysis in a time-intensive and expensive process. Point-of-care diagnostics are instead low-cost, easy-to-use, and rapid tests performed at ...
How does a cloud stay cool under direct sunlight—or seem to vanish in infrared? In nature, phenomena like white cumulus clouds, gray storm systems, and even the hollow hairs of polar bears offer remarkable lessons in balancing ...
Optical biosensors use light waves as a probe to detect molecules, and are essential for precise medical diagnostics, personalized medicine, and environmental monitoring.
