Chiral molecule identification system and method based on frustrated total reflection light spin Hall effect

Abstract

The invention discloses a chiral molecule identification system based on the spinning Hall effect of frustrated total reflection light, which sequentially comprises a front selection light path, an enhanced chip structure, a rear selection light path and an electric coupling element CCD (Charge Coupled Device), the spinning Hall effect of light is enhanced through the light paths, so that the CCD can capture a light spot and can read a spinning transverse movement value, and the spinning transverse movement value can be detected through the enhanced chip structure. Meanwhile, the invention provides a chiral molecule identification method based on the frustrated total reflection light spin Hall effect, the optical spin transverse movement value in the light intensity data is read by the identification system, the optical rotation angle is solved according to the optical spin transverse movement value, then the specific rotation of the chiral molecule solution is solved through the calculated optical rotation angle, and the chiral molecule is identified through the chiral molecule identification method based on the frustrated total reflection light spin Hall effect. And obtaining the category of the corresponding molecular material according to the calculated specific rotation of the chiral molecular solution. The method is suitable for identifying all chiral molecular solutions.

Description

technical field [0001] The invention relates to the field of material identification, in particular to a system and method for identifying chiral molecules based on the frustrated total reflection optical spin Hall effect. Background technique [0002] Chirality refers to the property that an object cannot be superimposed on its mirror image, and a chiral substance and its mirror image are called chiral enantiomers. Chiral molecules refer to molecules whose objects and their mirror images cannot be superimposed on each other and have a certain configuration or conformation. Chiral molecules widely exist in nature and living organisms, and play an important role in research fields such as pharmacology, chemical synthesis, and life sciences. Due to the common chemical and physical properties of left-handed molecules and right-handed molecules, it is very difficult to detect them. The existing chiral analysis technologies mainly include: piezoelectric and optical gas sensors,...
