Pediatric photosensitivity [PDF]

Photodermatology, Photoimmunology & Photomedicine, 2012
SummaryPhotosensitivity is a rarely encountered problem in the pediatric population. It may be caused by a diverse group of primary, idiopathic photosensitivity conditions, or may reflect photoexacerbation of an existing dermatosis. In addition, there are several genodermatoses, metabolic disorders, and connective tissue disorders that can present with

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

Advanced Optical Materials, EarlyView.
Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...

Biofilm‐Binding Phages Enhance Biofilm Eradication by Synergistic Photothermal and Photodynamic Therapy

Advanced Science, EarlyView.
Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...

A Molecular Engineering Strategy to Fine‐Tune Phototoxicity of AIE Probes for Super‐Resolution Imaging of Mitochondrial Cristae Dynamics

Advanced Science, EarlyView.
Regulation of molecular packing, phototoxicity, and ROS output of AIE photosensitizers is achieved through carboxylation and alkyl‐chain‐length tuning. The probe designed via this strategy enables super‐resolution visualization of inner‐mitochondrial‐membrane cristae dynamics under controlled oxidative stress, and fluorescence‐lifetime imaging of ...

Research on selective uptake of photosensitizer C3N4@RP by different cancer cells

Materials Research Express, 2022
Photodynamic therapy (PDT), as a clinical treatment, can remove malignant cells upon laser irradiation by selective uptake of photosensitizer (PS). The relative contribution of these antitumor effects depends largely on the dose and uptake of PS. In this
