“…The rate of photo-bleaching of PS was estimated from the decrease in the intensity of their fluorescence depending on the light dose density. The intensity of their fluorescence was determined using spectra-analyzer LESA-01-BIOSPEC (Biospec, Moscow, Russia) with an extended dynamic range [23,24]. The irradiation was carried out in a cyclic mode, the fluorescence intensity was measured in the pauses between irradiation intervals under excitation with lasers with a light wavelength of 633 nm (MS, Cholosens) or 532 nm (derivatives of bacteriochlorin-tetra-cationic (3-PyBrE) 4 BCBr 4 and electro-neutral (3-PyBS) 4 BC).…”

The aim of this work is the study of antibacterial photodynamic inactivation (APDI) of Escherichia coli (on the example of a model E. coli K12 TG1), the influence of the charge of photosensitizer (PS) molecules on the efficiency of binding with these Gram-negative bacteria. The results obtained confirm that PSs based on polycationic phthalocyanines and synthetic bacteriochlorins provide effective photodynamic inactivation of E. coli, much higher than monocationic methylene blue and electro-neutral bacteriochlorin derivative. The efficiency of APDI, assessed by the intensity of bioluminescence of model E. coli K12 TG1 bacteria, correlates with the charge of PS molecules and the efficiency of electrostatic binding of PS to bacterial cells.

In-fiber whispering gallery mode (WGM) microsphere resonators have received remarkable attention due to the superiorities of compact structure, high stability and self-alignment. As an in-fiber structure, WGM microsphere resonators have been demonstrated in various applications, such as sensors, filters and lasers, which have significant impacts on modern optics. Herein, we review recent progress of in-fiber WGM microsphere resonators, which involve fibers of diverse structures and microspheres of different materials. First, a brief introduction is given to in-fiber WGM microsphere resonators, from structures to applications. Then, we focus on recent progresses in this field, including in-fiber couplers based on conventional fibers, capillaries and micro-structure hollow fibers, and passive/active microspheres. Finally, future developments of the in-fiber WGM microsphere resonators are envisioned. Graphical Abstract
