Chirality in Nature02:30

Chirality in Nature

16.3K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Chirality

28.8K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Prochirality

4.8K
The concept of prochirality leads to the nomenclature of the individual faces of a molecule and plays a crucial role in the enantioselective reaction. It is a concept where two or more achiral molecules react to produce chiral products. A typical process is the reaction of an achiral ketone to generate a chiral alcohol. Here, the achiral reactant reacts with an achiral reducing agent, sodium borohydride, to generate an equimolar mixture of the chiral enantiomers of the product. For example, an...

Area of Science:

  • Plasmonics and Nanophotonics
  • Chirality and Chiroptical Phenomena
  • Materials Science and Engineering

Background:

  • Molecular chirality is crucial in chemistry, biology, and medicine.
  • Plasmonic nanostructures can emulate chiral molecules with unique optical properties.
  • Current plasmonic chiral structures typically have static, non-tunable responses.

Purpose of the Study:

  • To outline strategies for reconfiguring the chiroptical responses of plasmonic nano- and micro-objects.
  • To enable dynamic manipulation of optical chirality in artificial structures.
  • To explore potential applications of reconfigurable chiral plasmonics.

Main Methods:

  • Review and conceptualization of different strategies for reconfiguring plasmonic chiroptical responses.
  • Investigation of stimuli-responsive mechanisms for altering nanostructure conformation and optical signature.
  • Analysis of how structural changes impact chiroptical properties.

Main Results:

  • Demonstrated that chiroptical responses of plasmonic nanostructures can be dynamically reconfigured.
  • Showcased that either the chiroptical signature, 3D structure, or both can be altered postfabrication.
  • Identified various stimuli and strategies for achieving this reconfiguration.

Conclusions:

  • Plasmonic nanostructures with reconfigurable chirality offer a promising platform for advanced optical devices.
  • These dynamic structures have significant potential in polarization conversion, enantioselective analysis, chiral sensing, and catalysis.
  • The ability to tune chiroptical properties postfabrication opens new avenues in nanophotonics and chiral technologies.
