Completely Chiral Optical Force for Enantioseparation [PDF]
Scientific Reports, 2016 AbstractFast and reliable separation of enantiomers of chiral nanoparticles requires elimination of all the forces that are independent of the nanoparticle handedness and creation of a sufficiently strong force that either pushes different enantiomers in opposite directions or delays the diffusion of one of them with respect to the other.

Possible Enantioseparation of Racemic Ribose on Chiral Surface Formed by Adsorption of Nucleobases [PDF]
LifeThe paper proposes a putative prebiotic scenario leading to homochirality in the RNA world. In this scenario, racemic ribose, the only chiral moiety in RNA, was enantioseparated (in its pyranose form) on a chiral surface formed by the adsorption of ...

Bound States in the Continuum in All‐Dielectric Metasurface: Separation of Sub‐10 nm Enantiomers
Advanced Photonics Research, 2022 Enantioseparation is crucial in pharmaceutics and agrochemicals. Compared to the current chemical technique, the optical enantioseparation is more effective means yet hampered by the weak chiral optical force. Recently, plasmonic nanostructures have been

Stationary phases based on the nanoparticles for pharmaceutical and biomolecule separations [PDF]
Nanochemistry Research, 2021 Because of impossibility to achieve a general column for separation purposes, columns must be amended in order to acquire specific chemical characteristics such as hydrophobic, hydrophilic or ionic interactions.
