Abstract
Zn phthalocyanine with improved synthesis suitable for bulk production shows extremely high antimicrobial efficacies even under weak indoor light. The dye-impregnated cellulose material inactivates over 99.996% of drug-resistant C. albicans, S. aureus and E. faecalis in just one hour exposure with consumer-grade fluorescent lamps and diodes.
