A system for transferring near-UV and/or UV photons with engineered angular momentum on to matter, and treat organic and inorganic substances and/or impurities comprising a coherent or incoherent source of near-UV and/or UV photons, and one or more angular momentum generators configured to deliver near-UV and/or UV photons with optimized spin angular momentum (SAM), orbital angular momentum OAM, and/or a SAM/OAM combination to target organic or inorganic substance and/or impurity, wherein the angular momentum generators are scalable such that they can be fabricated as a stand alone structure, as a structure fabricated on the package of the near-UV and/or UV photon source, or as an integral part of the near-UV and/or UV photon source.
