Photodynamic treatment with phenothiazinium photosensitizers kills both ungerminated and germinated microconidia of the pathogenic fungi Fusarium oxysporum, Fusarium moniliforme and Fusarium solani. [PDF]

The search for alternatives to control microorganisms is necessary both in clinical and agricultural areas. Antimicrobial photodynamic treatment (APDT) is a promising light-based approach that can be used to control both human and plant pathogenic fungi.

Enhanced Photocatalytic Wastewater Purification and Bacterial Elimination via Copper Ion Irradiation‐Induced Modification of BiOCl

Advanced Science, EarlyView.
This study presents a copper ion irradiation method to achieve the modification function of BiOCl. By using high‐energy ion beams to introduce impurity ions inside the material, the intrinsic electric field of BiOCl is optimized, promoting the separation of photogenerated carriers and enhancing the photocatalytic activity.
