External Stimuli‐Activable Single‐Atom Nanozymes for Bioapplications
Small, EarlyView.Stimuli‐activable single‐atom nanozymes (SANs) are reviewed from materials design to biomedical applications. We explain electronic‐structure tuning principles and synthesis strategies that maximize the responsiveness of metal active sites and supports to light, ultrasound, and magnetic fields.

Activatable smart contrast agents for photoacoustic imaging
Smart Molecules, EarlyView.This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Smart Molecules, EarlyView.We constructed a novel excellent photodynamic drug without heavy atoms based on the conventional BODIPY photosensitizer, and then obtained a photodynamic vesicle with efficient tumor targeting (BDPM@OMVs) by bacterial extravasation. Multiple reactive oxygen species were efficiently generated under light irradiation, and the spontaneous elimination of ...

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.

Australian Endodontic Journal, EarlyView.ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

Journal of the European Academy of Dermatology and Venereology, EarlyView.In this RCT, KOH 5% demonstrated superior clinical success to diclofenac 3% and placebo at the end of treatment in patients with mild‐to‐moderate actinic keratosis and comparable long‐term efficacy to diclofenac. Its fast onset of efficacy and favourable tolerability make KOH a valuable treatment option in early‐stage actinic keratosis treatment ...

Oral Diseases, EarlyView.ABSTRACT Objective This randomized controlled trial evaluated the 24‐month effectiveness of a nonsurgical intervention for peri‐implant mucositis, comparing a 15% ozonated sunflower oil hydrogel with a 1% chlorhexidine gel. Methods Thirty patients with 360 peri‐implant mucositis sites were treated in a split‐mouth design, receiving both therapies in ...
