Tracking cells with omnidirectional visible laser particles
Credit: by Shui-Jing Tang, Paul H. Dannenberg, Andreas C. Liapis, Nicola Martino, Yue Zhuo, Yun-Feng Xiao, and Seok-Hyun Yun Laser particles are micrometre and nanometre lasers in the form of particles dispersible in aqueous solution, which have attracted considerable interest in the life sciences as a promising new optical probe. Laser particles emit highly bright light with extremely narrow spectral bandwidth. By transferring laser particles into live cells as shown in Figure 1, individual cells in a heterogeneous population can be tracked using each intracellular particle's specific spectr...
