Effect of novel porphyrazine photosensitizers on normal and tumor brain cells [PDF]

, 2020
Photodynamic therapy (PDT) is a clinically approved procedure for targeting tumor cells. Though several different photosensitizers have been developed, there is still much demand for novel photosensitizers with improved properties.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

D‐type neuropeptide decorated AIEgen/RENP hybrid nanoprobes with light‐driven ROS generation ability for NIR‐II fluorescence imaging‐guided through‐skull photodynamic therapy of gliomas

Aggregate
Glioma is one of the most common malignant tumors of the central nervous system, leading high mortality rates in human. Aggregation‐induced emission (AIE) photosensitizers‐based photodynamic therapy (PDT) has emerged as a promising therapeutic strategy ...

Photodynamic Therapy for Glioblastoma: Potential Application of TiO₂ and ZnO Nanoparticles as Photosensitizers

Pharmaceutics
Despite aggressive current therapies against glioblastoma (GB), residual tumor cells may remain at the edge of the surgical cavity after resection. These cells can rapidly proliferate, giving rise to tumor recurrence in more aggressive and drug-resistant

Highly efficient optogenetic cell ablation in C. elegans using membrane-targeted miniSOG. [PDF]

, 2016
The genetically encoded photosensitizer miniSOG (mini Singlet Oxygen Generator) can be used to kill cells in C. elegans. miniSOG generates the reactive oxygen species (ROS) singlet oxygen after illumination with blue light.

Chronic Photosensitivity

Dermatologic Clinics, 1986
Chronic photosensitivity is an incompletely understood syndrome that is difficult to diagnose and treat. Persistent light reaction, actinic reticuloid, and photosensitive eczema most commonly occur in middle-aged and elderly patients and have overlapping features.
