WebChirality (physics) A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality ). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called ... WebChirality has been reported to play an important role in controlling and mediating the self-assembly of gels.
