Chiral molecules can present different chemical properties. For applications like drug delivery and diagnosis, it is important to detect chiral signals in mixtures. Although electronic circular ...

Circular dichroism (CD) spectroscopy has long been regarded as a low-resolution technique used to obtain an estimate of the a-helix and b-sheet content of proteins. This view of CD, though widely held ...

For a long time, it was thought that amorphous solids do not selectively absorb light because of their disordered atomic structure. A new study disproves this theory and shows that amorphous solids ...

Chiral molecules exist in two forms, called enantiomers, which are mirror images of each other and non-superimposable—much like a pair of hands. While they share most chemical and physical properties, ...

What is Circular Dichroism Microspectroscopy? Circular Dichroism Microspectroscopy combines the foundational science of circular dichroism—which measures differences in the absorption of left- and ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

Metamaterials are a novel class of man-made materials with engineered qualities that surpass those found in nature. Unlike most substances, whose behavior is determined by chemical makeup, ...
