Query: Micro-OptoMechanical Movements (MOMs) with SoftOxometalates (SOMs):
  Controlled Motion of Single Soft-Oxometalate Pea-pods Using Exotic Optical
  Potentials   An important challenge in the field of materials design and synthesis is to
deliberately design mesoscopic objects starting from well-defined precursors
and inducing directed movements in them to emulate biological processes.
Recently, mesoscopic metal-oxide based Soft Oxo Metalates (SOMs) have been
synthesized from well-defined molecular precursors transcending the regime of
translational periodicity. Here we show that it is actually possible to
controllably move such an asymmetric SOM-with the shape of a `pea-pod' along
complex paths using tailor-made sophisticated optical potentials created by
spin-orbit interaction due to a tightly focused linearly polarized Gaussian
beam propagating through stratified media in an optical trap. We demonstrate
motion of individual trapped SOMs along circular paths of more than 15 $\mu$m
in a perfectly controlled manner by simply varying the input polarization of
the trapping laser. Such controlled motion can have a wide range of application
starting from catalysis to the construction of dynamic mesoscopic
architectures.
