Chiral field
WebChiral nanophotonic materials are promising candidates for biosensing applications because they focus light into nanometer dimensions, increasing their sensitivity to the molecular signatures of their surroundings. Recent advances in nanomaterial-enhanced chirality sensing provide detection limits as low as attomolar concentrations (10–18 M) … WebSep 8, 2016 · Furthermore, chiral plasmonic metamaterials can efficiently enhance the optical signals from biomolecules [145–148]. This is because of the enhancement of the chiral field in the near-field region, known as the superchiral field, which may provide a method for detecting the handedness of a single molecule.
