Here, we demonstrate, for the first time, the robust sorting of Mie (size ~ wavelength) chiral particles with different handedness at an air鈥搘ater interface using optical lateral forces induced by a single linearly polarized laser beam. The nontrivial physical interactions underlying these ...
Optical sorting: Forcing mirror-image microparticles to go their own way A setup that uses lasers to automatically sort compounds with nearly imperceptible chemical differences could improve the efficiency of drug manufacturing. Many pharmaceuticals are difficult to purify because they are chiral, meaning...
Recently, enantioselective molecular sensing assisted by Ag chiral nanoparticles (AgCNPs) was also demonstrated in the deep-UV region108, where the effects of superchiral fields are absent. A helical arrangement of core/surface AgCNPs cannot generate a localized surface plasmon resonance (LSPR) at ...

Lateral optical forces induced by linearly polarized laser beams have been predicted to deflect dipolar particles with opposite chiralities toward opposite transversal directions. These"chirality-dependent"forces can offer newpossibilities for passive all-optical enantioselective sorting of chiral particles, ...

Helical structures continue to inspire, prompted by examples such as DNA double-helix and alpha-helix in proteins. Most synthetic polymers also crystallize as helices, which relieves steric clashes by twisting, while keeping the molecules straight for th
Figure 3c indicates that the ratio of platelets exhibiting a screw dislocation over the total number of crystallites increases with the growth rate, and it confirms that dislocation assisted growth can be extended to colloidal systems beyond the seminal prediction by Burton–Cabrera–Frank for atomic...
Our synthetic protocol consists of a microwave-assisted hydrothermal bottom-up synthesis using arginine (Arg) and ethylenediamine (EDA) as precursors33. The corresponding nitrogen-doped N-CNDs were shown to possess a nanoscale amorphous core that is covered by an amino-rich surface33,34. ...
