Dicyanine. Things To Know About Dicyanine.

The fluorescence quenching property of disulfide dicyanine dyes provides an excellent background; however, in order to use the dicyanine dyes in optical imaging, the fluorescent strength needs to be enhanced at the tumor site. Therefore, we investigated the spectral properties of disulfide dicyanine dyes in the presence of GSH. We would like to show you a description here but the site won’t allow us.Mo, S., Zhang, X., Hameed, S., Zhou, Y., & Dai, Z. (2020).
