Chiral Particle Separation by a Nonchiral Microlattice [PDF]
Physical Review Letters, 2012 We conceived a model experiment for a continuous separation strategy of chiral molecules (enantiomers) without the need of any chiral selector structure or derivatization agents: Micro-particles that only differ by their chirality are shown to migrate along different directions when driven by a steady fluid flow through a square lattice of cylindrical ...

Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]
Despite the wide range of HPLC stationary phases available for reversed-phase high-performance liquid chromatography (RP-HPLC) and the in-depth studies using probes to highlight differences between them, there is very little in the way of stationary ...

Spontaneous demixing of chiral active mixtures in motility-induced phase separation
New Journal of Physics, 2023 The demixing and sorting strategies for chiral active mixtures are crucial to the biochemical and pharmaceutical industries. However, it remains uncertain whether chiral mixed particles can spontaneously demix without the aid of specific strategies.
