Cancerous Cell Death from Sensitizer Free Photoactivation of Singlet Oxygen
Singlet oxygen (1O2) is an electronic state of molecular oxygen which plays a major role in many chemical and biological photo‐oxidation processes. It has a high chemical reactivity which is commonlyExpand

A high-power tunable Raman fiber ring laser for the investigation of singlet oxygen production from direct laser excitation around 1270 nm.
We report on the development of a tunable Raman fiber ring laser especially designed for the investigation of the 3Σ(-)(g) →1 Δg transition of molecular oxygen. Singlet oxygen (1Δg) is a reactiveExpand

Phenotypic diversity and temporal variability in a bacterial signaling network revealed by single-cell FRET
We present in vivo single-cell FRET measurements in the Escherichia coli chemotaxis system that reveal pervasive signaling variability, both across cells in isogenic populations and within individualExpand

Production Rate and Reactivity of Singlet Oxygen 1O2(1Δg) Directly Photoactivated at 1270 nm in Lipid Nanocapsules Dispersed in Water
Singlet oxygen is produced through the O2 [3∑g–] → O2 [1Δg] transition of molecular oxygen upon direct 1270 nm laser irradiation in water. The non water-soluble 1,3-diphenylisobenzofuran (DPIBF) isExpand

Singlet oxygen (1O2) generation upon 1270 nm laser irradiation of ground state oxygen (3O2) dissolved in organic solvents: Simultaneous and independent determination of 1O2 production rate and
Abstract Direct photo-production of singlet oxygen, via 1270 nm laser excitation of molecular oxygen, has been the focus of recent articles. The chemical traps 1,3-diphenylisobenzofuran and rubreneExpand

Chapter 4:Production of Singlet Oxygen by Direct Photoactivation of Molecular Oxygen
In this chapter, we will discuss singlet oxygen direct production schemes that imply only natural transition of molecular oxygen that we name direct photoactivation. Our purpose will be to highlightExpand

Dynamical thermal dose models and dose time-profile effects
Abstract Introduction: Models of dose-effect relationships seek systematic and predictive descriptions of how cell survival depends on the level and duration of the stressor. The CEM43 thermal doseExpand

Grating-Free and Bragg-Grating-Based Raman Lasers Made With Highly Nonlinear Photonic Crystal Fibers
We study both experimentally and theoretically power and spectral characteristics of two types of Raman fiber lasers (RFLs) fully made with highly nonlinear photonic crystal fibers (HNL-PCFs). TheExpand
