The possibility of chirally sensitive optical forces was recently recognised by a handful of authors, including members of the FOAM group [1,2,3].
RPC, AMY and a collaborator were the first to show that structured light in the form of one-dimensional helicity fringes  can give rise to a purely discriminatory optical force for chiral molecules and that such forces might form the basis of chiral matter-wave interferometry (CMWI) [1,2,3]. RPC and collaborators have since shown how to produce two- and even three-dimensional helicity lattices . See also the review articles [6,7].
RPC, AMY and DM are continuing to develop the theory of chiral optical forces, focusing in particular on the importance of rotational states and the experimental demonstration of CMWI with Dr J P Cotter at Imperial College, London. Potential applications for CMWI include absolute measurements of enantiomeric excess.
