Safe near infrared light for fast polymers surface sterilization using organic heaters
Valentin Launay, Frédéric Dumur, Laurent Pieuchot, Jacques Lalevée
Abstract
NIR dyes (called heaters) are here in situ embedded in the polymeric materials so that they could produce a strong photothermal effect upon NIR light. The eradication of Escherichia coli was demonstrated after only 2 min of safe NIR irradiation.
