Quantitative analysis of hydrogen peroxide using ratiometric fluorescent probe-doped silica nanoparticles

Fluorescent nano- and microparticles for sensing cellular microenvironment: past, present and future applications

“…The biocompatible and ratiometric reactive dye PL1 was used to detect the endogenous concentration of H 2 O 2 in RAW264.7 macrophages and HEK 293 T cells. Later on, Kim's group 166 prepared silica nanoparticles decorated with PL1. The aim was to develop a new scaffold as a promising tool for monitoring hydrogen peroxide.…”
