Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences have recently proposed a design concept for a tunable broadband perfect absorber based on non-split coupling of ...
Label-free, non-invasive, and quantitative monitoring of cellular activities is crucial for understanding various biological processes and the response of cells to therapeutic drugs.
The extreme accuracy and speed of NBA three-pointer Stephen Curry's long-range shots are well known to basketball fans around the world, but accuracy and speed are also a focus of research in biochemical testing. Dr. Yen ...
Researchers at Karolinska Institutet in Sweden have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique, described as a proof-of-concept in a paper in the journal Advanced Science, ...
A group of photonics researchers at Tampere University have introduced a novel method to control a light beam with another beam through a unique plasmonic metasurface in a linear medium at ultra-low power. This simple linear ...
A new technology is using particles of gold to make colors. With further work, the method developed at Aalto University could herald a new display technology.
Compact terahertz functional devices are highly useful for high-speed wireless communication, biochemical sensing and non-destructive inspection. However, controlled terahertz generation, alongside transport and detection ...
Trace gas sensing is critical for monitoring environmental pollution and detecting volatile organic compounds released from the human body. As a powerful analytical tool for identifying trace molecules, surface-enhanced Raman ...
A new publication from Opto-Electronic Advances considers research on photonic crystal topological states beyond the optical diffraction limit.
The left hand looks like the right hand in the mirror but the left-handed glove does not fit on the right hand. Chirality refers to this property where the object cannot be superimposed on to the mirror image. This property ...
