LASER To Bacteria: Resistance Is Futile
A laser-activated antimicrobial offers hope for new treatments of bacterial infections, even those that are resistant to current drugs. Research published today in the open access journal BMC Microbiology describes the use of a dye, indocyanine green, which produces bacteria-killing chemicals when lit by a specific kind of laser light. Michael Wilson led a team from UCL (University College London) who carried out experiments showing that activated indocyanine green is capable of killing a wide range of bacteria including Staphylococcus aureus, Streptococcus pyogenes and Pseudomonas aeruginosa. The dye is safe for humans. The strength of this new approach lies in the variety of ways in which the chemicals produced by the activated dye harm bacteria. Read More...
