dc.description.abstractConjugated polymer particles are brightly fluorescing and stable materials for live cell imaging. Combination of conjugated polymers with a whispering gallery mode (WGM) resonator allows laser emission from microscale particles. Once internalized by cells, the mode pattern of the laser emission can be used for tagging and tracking, as each laser spectrum represents a bar code to identify individual cells. However, currently these particle systems are limited by their large size, which might interfere with cellular functions. Here we present, stimulated resonance Raman scattering (SRRS) in small conjugated polymer microparticles as a new method for generating narrow emission as an alternative to WGM-based laser emission. This opens up spectral range for multiplexing optical readout and multicolor imaging of live cells. We discuss the synthesis of monodisperse micron-sized poly(fluorene-co-divinylbenzene) particles and characterize their WGM and SRRS emission. Finally, we showcase how these particles and their emission can be employed in live cell imaging and tagging.
