Influence of stomach mucosa tissue on the efficacy of intragastric antibacterial PDT
To estimate the light action spectrum for the in vivo phototherapy of H. pylori in the visible range, we performed a simulation of the light transmitted by a simple optical model of the gastric wall structure.

Toward better microbial safety of wheat sprouts: chlorophyllin-based photosensitization of seeds
The chlorophyllin-based photosensitization treatment, being nonthermal, environmentally friendly and cost-effective, has huge potential for microbial control of highly contaminated germinated wheat sprouts and seeds used to produce sprouts.

Mosquito larvae control by photodynamic inactivation of their intestinal flora – a proof of principal study on Chaoborus sp.
The aim of this study is to investigate the potential of photodynamic agents to combat mosquito larvae, the carriers of dangerous pathogens around the world. All photosensitizers tested were observed in the digestive tract of the larvae.

About this collection
Microbial pathogens trouble mankind in practically all habitats around the globe. Motivated by the outstanding success of Photodynamic Inactivation in treatment of infections from head to feet, novel and very promising applications based on the light-induced and photosensitizer-mediated overproduction of reactive oxygen are constantly identified and explored by the research community, with great imagination and creativity.
This virtual themed issue provides two comprehensive reviews and a selection of articles on novel and promising developments in Photodynamic Inactivation ranging from biomaterial-conjugated photosensitizers to photoantimicrobial textiles. The collection will hopefully stimulate efforts to expand the convincing benefits of the antimicrobial photodynamic approach into new fields of application in human medicine and beyond.
