Study Shows Increased Effectiveness Of Light-Activated Antimicrobial Agents Against MRSA

Many bacteria capable of causing life-threatening infections are now resistant to a wide range of antibiotics.  It is essential, therefore, that alternatives to antibiotics are developed for use in the prevention and treatment of such infections. Light-activated antimicrobial agents (LAAAs) are one possible new approach to this problem. LAAAs are compounds that display no antimicrobial activity in the dark but, when exposed to light of a certain wavelength, can kill microbes in the vicinity.  One of the essential attributes of any antimicrobial agent, including a LAAA, is that it be effective at low concentrations so as to reduce the risks of any toxicity to the patient.

The new LAAAs as seen through a very powerful electron microscope. The diameter of each particle is approximately 0.000000005 metre.
