title: Whispering gallery mode laser based on antitumor drug-dye complex gain medium.
abstract: Optofluidic lasers have emerged as a new research field over the past few years. Most frequently they use conventional dye molecules as the gain medium. In this Letter, we demonstrate a laser emission produced by the coupling of the evanescent whispering gallery modes that resonate in a cylindrical microresonator to a newly developed gain medium. This medium is formed by attachment of a 7-nitrobenzo [c] [1,2,5]-oxadiazol-4-yl fluorescent tag to tamoxifen, the most widely used drug in the treatment of breast cancer. The antitumor character of the gain medium paves the way to novel biophotonic applications.
