Systems and methods are disclosed herein for applying near-infrared optical energies and dosimetries to alter the bioenergetic steady-state trans-membrane and mitochondrial potentials (&Dgr;Ψ-steady) of all irradiated cells through an optical depolarization effect. This depolarization causes a concomitant decrease in the absolute value of the trans-membrane potentials &Dgr;Ψ of the irradiated mitochondrial and plasma membranes. Many cellular anabolic reactions and drug-resistance mechanisms can be rendered less functional and/or mitigated by a decrease in a membrane potential &Dgr;Ψ, the affiliated weakening of the proton motive force &Dgr;p, and the associated lowered phosphorylation potential &Dgr;Gp. Within the area of irradiation exposure, the decrease in membrane potentials &Dgr;Ψ will occur in bacterial, fungal and mammalian cells in unison. This membrane depolarization provides the ability to potentiate antimicrobial, antifungal and/or antineoplastic drugs against only targeted undesirable cells. |
