Abstract: A particle including at least one aliphatic polymer having anti-microbially active quaternary ammonium groups chemically bound thereto, is provided. The particle may be used to inhibit populations of microorganisms and biofilms. Also provided are methods for the preparation of such particles and uses thereof for the inhibition of microorganisms.

Abstract: The present invention discloses a selective and a non-selective method and means of treating microbial diseases in local infections. The novel method comprising the step of emitting a beam of a blue light towards the tissue to be treated, wherein the beam is having a wavelength from 400 to 550 nanometers and further wherein the temperature of said tissue is not exceeding about 42° C. along the procedure or immediately after it so that a selective phototoxic effect is exerted. A cost effective device for selectively or non-selectively exerting phototoxic effect by emitting a beam of blue light towards a tissue to be treated is also provided useful, especially for dental application.
