Highly selective generation of singlet oxygen from dioxygen with atomically dispersed catalysts

Abstract

Singlet oxygen (1O2) as an excited electronic state of O2 plays a significant role in the ubiquitous oxidative processes from enzymatic oxidative metabolism to industrial catalytic oxidation. Generally, 1O2 can...

Reactive oxygen species-upregulating nanomedicines towards enhanced cancer therapy

“…7A). 102 In addition, MnO x nanosheets also have the ability to generate 1 O 2 under acidic triggering (Fig. 7B).…”

Single and dual metal atom catalysts for enhanced singlet oxygen generation and oxygen reduction reaction

“…This leads to selective and enhanced singlet oxygen ( 1 O 2 ) sensitization, which is used for the PDT of tumor cells. 14 Moreover, charge transfer between DACs and O 2 is investigated using DFT calculations, finding the importance of magnetic coupling on the performance of DACs. 15 In addition to studying charge transfer using DFT calculations, the electronic structure of materials in their excited states can be examined using time-dependent DFT (TD-DFT) calculations to provide additional fundamental insights into the photocatalytic process.…”

“…Las moléculas que tienen esta prepiedad son, entre otras, la clorofila, la eosina y el azul de metileno. El oxígeno singulete no es un radical, sino representa un estado excitado más bajo de la molécula de oxígeno diatómico (O2) (Ma et al, 2022).…”
