  It is shown that chiral plasmons, characterized by a longitudinal magnetic
moment accompanying the longitudinal charge plasmon, lead to electromagnetic
near-fields that are also chiral. For twisted bilayer graphene, we estimate
that the near field chirality of screened plasmons can be several orders of
magnitude larger than that of the related circularly polarized light. The
chirality also manifests itself in a deflection angle that is formed between
the direction of the plasmon propagation and its Poynting vector. Twisted van
der Waals heterostructures might thus provide a novel platform to promote
enantiomer-selective physio-chemical processes in chiral molecules without the
application of a magnetic field or external nano-patterning that break
time-reversal, mirror plane or inversion symmetry, respectively.
