Title: Innovations of Sungmun Lee in Reactive Oxygen Species Detection

Introduction

Sungmun Lee is an accomplished inventor based in Dunwoody, GA (US). He has made significant contributions to the field of chemical detection, particularly in the area of reactive oxygen species (ROS). His innovative work has led to the development of a unique patent that enhances the ability to detect these critical species in various biological contexts.

Latest Patents

Sungmun Lee holds a patent for "Reduced dye probes for the detection of radical oxygen species." This invention describes reduced dyes, such as hydrocyanines and deuterocyanines, which are capable of detecting one or more reactive oxygen species. The reduced dyes exhibit minimal fluorescence due to disrupted π conjugation. However, upon reaction with ROS, these dyes are oxidized, regenerating the extended π conjugation and resulting in a significant increase in fluorescence intensity. The oxidized dye is generally membrane impermeable, but many of the reduced dyes are membrane permeable, allowing them to accumulate in cells and tissues. This accumulation amplifies the signal for imaging ROS, such as hydroxide radical and superoxide, in serum, cell cultures, tissue explants, and in vivo.
