Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

open access: yesPhotochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

Human ocular‐discomfort‐free thresholds for 222 nm Far‐UVC irradiation: A prospective interventional study

open access: yesPhotochemistry and Photobiology, EarlyView.
Eye discomfort induced by 222 nm far‐UVC irradiation is significantly correlated with both irradiance and radiant exposure dose. The red circles indicate conditions with significant differences in the number of eye discomfort compared to the control group (blue circles), while the green circles indicate conditions with no difference from the control ...
