Generation And Detection Of Singlet Oxygen (1O2) By Upconversion Nanoparticles (UCNP)

Singlet oxygen is a reactive oxygen species, as its chemical reactivity derives from its characteristic electronically-excited state. This species has attracted researches in the last years because of the involvement of singlet oxygen in many important atmospheric, physical, chemical, biological, and therapeutic processes. Currently, nanoparticles that present UC luminescence have become a research field, related to the potential for application in biological images, which has led to the search for intensifications in the signals emitted by upconversion.
