Abstract Anaphylaxis is a life-threatening hypersensitivity reaction. Clinical observations suggest heightened susceptibility during viral infections, yet the mechanisms remain poorly defined. Here, we show that both active and passive IgG-mediated anaphylaxis were exacerbated in the setting of acute viral infection.

Graphical Abstract Chemiresistive Sensors In article number 2405694, Máté J. Bezdek and co-workers present a chemiresistor for detecting oxygen at room temperature under light illumination. Inspired by the operating principles of dye-sensitized solar cells, the sensor is based on a carbon nanotube-titania hybrid bearing a rhenium photosensitizer that absorbs green light. The photoactivated device exhibits high oxygen selectivity, ppb-level sensitivity, humidity tolerance and multi-month stability.

1 Introduction Dioxygen (O2) is ubiquitous in the environment and is essential for life.[1] As such, the accurate measurement of O2 concentration is crucial for a range of applications spanning the medical, biological, and environmental sciences including water quality monitoring[2] and evaluating cell health or disease progression.[3, 4] Information about O2 levels is equally important in industrial settings, as exemplified by the central role of O2 detectors in personnel health...
