A Near Infrared Emission Feature from Visible Fluorescence Tails and its Correlation with Singlet Oxygen

open access: yesAdvanced Optical Materials, EarlyView.
A persistant NIR emission tail and feature at 923 nm is observed during photochemical singlet oxygen generation using various photosensitizers. While initially considered as singlet oxygen phosphorescence we show that it arises from the NIR‐tail of (visible) photosensitizer emission and the non‐linear increase of detector sensitivity.

Minimally Invasive Chemical Biopsy Needle with Self‐Wettable Extraction Phase For In Vivo Tissue Sampling During Medical Procedures

open access: yesAdvanced Science, EarlyView.
A new tissue sampling device using an acupuncture needle with bio‐compatible extraction sorbents in the recessed section is developed. The coating material using self‐wettable particles doesn't require solvent activation after sterilization. This device is applied for the anti‐cancer drug concentration monitoring during the in vivo lung perfusion ...

Cell Viability, Drug Screening, and Mechanism Study Under Mild Phototherapy Integrated Chemotherapy (PIC)

open access: yesAdvanced Science, EarlyView.
Mild phototherapy integrated chemotherapy (mild‐PIC) monitored by real‐time impedance spectroscopy enhances drug efficacy in liver cancer via the “More Light‐Aiding, Less Bonding (LALB)” mechanism, achieving higher targeting with lower toxicity. Abstract Phototherapy integrated chemotherapy (PIC) offers a promising cancer treatment strategy as single ...

Biosynthesis of H2S and Siderophores Targeting Gram‐Negative Bacterial Resistance to Reactive Oxygen Species

open access: yesAdvanced Science, EarlyView.
Discover how Gram‐negative bacteria develop resistance to reactive oxygen species, and how scientists aim to overcome this challenge. Abstract Reactive oxygen species (ROS) are a promising alternative bactericide. However, it is questioned that bacteria can potentially develop resistance to ROS, similar to their resistance against antibiotics and ...
