Throughout the 19th and 20th century, chirality has mostly been associated with chemistry.
However, while chirality can be very useful for understanding molecules, molecules are not …

Optical binding is a laser-induced inter-particle force that exists between two or more
particles subjected to off-resonant light. It is one of the key tools in optical manipulation of …

Optical forces are involved in many physical processes and are used routinely in the
laboratory for manipulating and cooling matter, from the micro down to the quantum scales. It …

Enantioselective optical forces have garnered significant attention, because they provide a
noninvasive means to separate chiral objects. A promising approach to enhance …

The question of how the orbital angular momentum of structured light might engage with
chiral matter is a topic of resurgent interest. By taking account of electric quadrupole …

Enantiomer separation opens great opportunities to develop the technologies of
pharmaceutics, chemicals, and biomedicine, but faces daunting challenges. Here, we …

The identification and separation of substances by chirality has always been an important
problem in biomedical research and industry. Light beams carry optical momentum, and can …

Raman optical activity underpins a powerful vibrational spectroscopic technique for
obtaining detailed structural information about chiral molecular species. The effect centers …

Chiral molecules are ubiquitous in nature; many important synthetic chemicals and drugs
are chiral. Detecting chiral molecules and separating the enantiomers is difficult because …

We report on a chiral optical Stern-Gerlach experiment where chiral liquid crystal
microspheres are selectively displaced by means of optical forces arising from optical …
