ACS Photonics, 2014
We report on the enhanced optical properties of chiral magnetic nanohelices with critical dimensions comparable to the ferromagnetic domain size. They are shown to be ferromagnetic at room temperature, have defined chirality, and exhibit large optical activity in the visible as verified by electron microscopy, superconducting quantum interference ...

The Lancet, 2000
Developments in synthetic and analytical chemistry have provided the tools to differentiate between two enantiomers (mirror images) of drugs or between the parent compound and metabolite(s) with respect to desired and undesired pharmacological effects.

Annual Review of Analytical Chemistry, 2010
The main goal of this review is to provide a brief overview of chiral separations to researchers who are versed in the area of analytical separations but unfamiliar with chiral separations. To researchers who are not familiar with this area, there is currently a bewildering array of commercially available chiral columns, chiral derivatizing reagents ...

Current Opinion in Biotechnology, 2003
New strategies are continually being developed for using enzymes to efficiently catalyse the enantioselective synthesis of chiral non-racemic compounds. Alternatives to asymmetric synthesis or kinetic resolution include dynamic kinetic resolution, deracemisation and enantioconvergent transformations.

Chirality and Chiral Recognition
2009This review summarizes the literature survey on chiral recognition from a theoretical view point. Nevertheless, experimental results in the gas phase are reported when they are relevant for the theoretical calculations. The review is divided into the following sections: general considerations; experiment vs.
