1. A method of treating biological surfaces comprising:
treating a biological surface with chlorhexidine together with electromagnetic radiation in the form of light of two different energy levels, a first light with photons having a majority energy in the range from 3.17 eV to 2.95 eV and a second light with photons having a majority energy in the range from 1.56 eV to 1.45 eV, wherein the photons of the first light and the second light are simultaneously directed against the biological surface.
 
29. A method of treating biological surfaces comprising:
treating a biological surface with electromagnetic radiation in the form of light of two different energy levels, a first light with photons having a majority energy in the range from 3.17 eV to 2.95 eV and a second light with photons having a majority energy in the range from 1.56 eV to 1.45 eV,
wherein photons of the first light and the second light are simultaneously directed against the biological surface, and
wherein the energy intensity ratio between the first light and the second light is in the range of 5:1 to 0.2:1.
