Design of surface nanostructures for chirality sensing based on quartz crystal microbalance
Beilstein Journal of Nanotechnology, 2022 Quartz crystal microbalance (QCM) has been widely used for various sensing applications, including chirality detection due to the high sensitivity to nanogram or picogram mass changes, fast response, real-time detection, easy operation, suitability in ...

Redox and optically active carbohelicene layers prepared by potentiodynamic polymerization
Electrochemistry Communications, 2020 This short paper describes the preparation of thin layers based on carbohelicenes, which are inherently chiral polyaromatics existing in the enantiomeric forms P and M. Specifically, [5]-, [6]- and [7]helicene were subjected to redox cycling between −1.5

Electromagnetic manifestation of chirality in layer-by-layer chiral metamaterials
Optics Express, 2013 The three-dimensional (3D) and two-dimensional (2D) chiral metamaterials (CMMs) have been proved to exhibit circular dichroism and circular conversion dichroism, respectively. The layer-by-layer chiral metamaterials, as a category of 3D CMMs, are expected to show the same properties as bulk 3D structures (e.g. helices).

Enantioselective assembly of multi-layer 3D chirality [PDF]
National Science Review, 2019 Abstract The first enantioselective assembly of sandwich-shaped organo molecules has been achieved by conducting dual asymmetric Suzuki-Miyaura couplings and nine other reactions. This work also presents the first fully C-C anchored multi-layer 3D chirality with optically pure enantiomers.

Layer-by-layer three-dimensional chiral photonic crystals
Optics Letters, 2007 We fabricate and characterize polymeric three-dimensional layer-by-layer chiral photonic crystals. The obtained circular dichroism from polarization stop bands is comparable with that of recently demonstrated circular-spiral photonic crystals. Moreover, telecommunication wavelengths are easily accessible with the layer-by-layer approach; even visible ...
