A research team from Politecnico di Milano and the University of Bayreuth (Germany) has developed an approach for the quick measurement of chirality across a broad wavelength range. In molecules, chirality occurs when molecules contain the same atoms, but arranged in mirror-image configurations — much like a pair of hands. The method addresses the challenge of distinguishing the chirality of a molecule; chiral molecules are almost identical in their physiochemical property. Circular dichroism — an optical property for which left-handed and right-handed enantiomers...Read full article

    chirality
    Chirality is a property of certain molecules and objects in which they are non-superimposable on their mirror images. In other words, a chiral object or molecule cannot be exactly superimposed onto its mirror image, much like a left and right hand. The term "chirality" comes from the Greek word cheir, meaning hand, emphasizing the handedness or asymmetry of the object or molecule. A molecule or an object with this property is said to be chiral, while its non-superimposable mirror image is...
    circular dichroism
    Circular dichroism (CD) is a spectroscopic technique used to study the structural characteristics of chiral (asymmetric) molecules, particularly biomolecules like proteins, nucleic acids, and certain small organic molecules. Circular dichroism measures the differential absorption of left-handed circularly polarized light compared to right-handed circularly polarized light as it passes through a sample. Key points about circular dichroism: Chirality: Chirality refers to the asymmetry in the...
