Families of Dyes

NIRvana Sciences is commercializing two families of dyes developed at NC State University: chlorins and bacteriochlorins. Chlorins have a violet excitation and emit between 600-725nm and we’re working on ways to extend emissions out to 800nm. Our bacteriochlorins usually have a peak absorption in the ultra violet region with emissions between 685nm-900nm.

If you would like to learn more about our Chlorin dyes, feel free to review this helpful journal article:
Synthetic Chlorins Bearing Auxochromes at the 3- and 13-Positions by Joydev K. Laha, Chinnasamy Muthiah, Masahiko Taniguchi, Brian E. McDowell, Marcin Ptaszek, and Jonathan Lindsey DOI: 10.1021/jo060208o
