Rate of oxygen disappearance from arterioles in rat mesentery measured with scanning phosphorescence quenching microscopy (PQM)

The FASEB Journal, 2010
The oxygen disappearance curve (ODC) recorded in an arteriole after rapid arrest of blood flow reflects the complex interaction between the HbO 2 dissociation curve and the kinetics of tissue respiration.

Impact of accumulated oxygen depletion (AOD) on measurements of oxygen tension (PO2) using phosphorescence quenching microscopy (PQM)

The FASEB Journal, 2008
PQM is a powerful method to measure PO 2 in microvessels. However, its application to stationary tissue and fluids has never been substantiated. Multiple flash excitations applied in PQM to the same sampled volume produce AOD and distort the measured PO 2

Oxygen dependence of respiratory rate (VO2) in rat spinotrapezius muscle in situ measured with phosphorescence quenching microscopy (PQM)

The FASEB Journal, 2012
Objective The sensitivity of isolated cells to PO2 is described by Hill's equation with a low Km (< 5 torr). Cells in intact tissues are more sensitive to O2 deficiency. To study the oxygen dependence of VO2 in muscle fibers we developed a method to register and interpret O2 disappearance curves (ODC).

Oxygenation through oral Ox66 in a two-hit rodent model of respiratory distress

Artificial Cells, Nanomedicine, and Biotechnology
Acute respiratory distress syndrome (ARDS) is a complication of pulmonary disease that produces life-threatening hypoxaemia. Despite ventilation and hyperoxic therapies, undetected hypoxia can manifest in capillary beds leading to multi-organ failure ...

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

Advanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Rationalizing the Unexpected Inefficiencies of 3D Porphyrin‐MOFs as Singlet Oxygen Photosensitizers Against Botrytis cinerea

Advanced Materials Interfaces
Porphyrin‐based MOFs (PMOFs) are known to be efficient photocatalysts and singlet oxygen (1O2) photosensitizers (PS) in solution, but their application in agriculture and food protection is practically unknown.

Circularly Polarized Red‐NIR Emission With High Dissymmetry Factor From Achiral [Mo6I8(OCOC2F5)6]2− Cluster Anion Embedded in a Bent‐Core Liquid Crystal Host

Advanced Optical Materials, EarlyView.
Associating a chiral bent core liquid crystal molecule, that self‐assembles into helical nanofilaments, with an achiral red‐NIR phosphorescent octahedral molybdenum cluster produces a hybrid material exhibiting efficient red‐NIR circularly polarized emission under UV excitation.
