Physical mechanisms of generation and deactivation of singlet oxygen.
TL;DR: Reactions of O2(∆g) are associated with significant applications in several fields, including organic synthesis, bleaching processes, and, most importantly, the photodynamic therapy of cancer, which has now obtained regulatory approval in most countries for the treatment of several types of tumors.

TL;DR: Insight is provided into the dynamics of diffusion in cells, which is pertinent to drug delivery, cell signalling and intracellular mass transport, and the effect of this viscosity increase is observed directly in the diffusion-dependent kinetics of the photosensitized formation and decay of a key cytotoxic agent.

Photoinhibition of Photosystem II
TL;DR: In this chapter, it is shown that the evidence behind the chemistry-based models and the photophysically oriented models can be brought together to build a mechanism that confirms with all types of experimental data.

Nonlinear Optical Materials for the Smart Filtering of Optical Radiation.
TL;DR: This Review gives emphasis to the nonlinear optical properties of photoactive materials for the function of optical power limiting and describes the known mechanisms of optical limiting for the different types of materials.

Time resolved studies of 1.27 micron luminescence from singlet oxygen generated in homogeneous and microheterogeneous fluids.
TL;DR: The technique was shown to be useful in measuring Tδ values in several microheterogeneous systems such as surfactant micelles, vesicles and human serum albumin and the singlet oxygen lifetimes determined directly agreed well with published values.
