Using Colistin as a Trojan Horse: Inactivation of Gram-Negative Bacteria with Chlorophyllin
Antibiotics, 2019 Colistin (polymyxin E) is a membrane-destabilizing antibiotic used against Gram-negative bacteria. We have recently reported that the outer membrane prevents the uptake of antibacterial chlorophyllin into Gram-negative cells.

Advanced Optical Materials, EarlyView.Hexagonal arrays of silicon nanodisks are proposed to control 1.5 µm emission of Er3+ ions. Toroidal dipole resonance of the nanodisk array generates accessible magnetic hot spots at the surface, leading to enhanced and highly directional magnetic dipole emission along the surface‐normal direction via the magnetic Purcell effect.
