Fluorescent conjugated block copolymer nanoparticles by controlled mixing

Abstract: Monitoring of the formation of stable fluorescent nanoparticles from controlled mixing of a THF solution of poly(fluorene ethynylene)-block-poly(ethylene glycol) in a microfluidic laminar flow crossjunction by spatially resolved fluorescence spectroscopy reveals the time scale of particle formation as well as incorporation of small molecule guests and the role of solvent mixing.

“…[4044] There have been significant efforts to create versatile semiconducting polymer nanoparticles (a small subset of which are Pdots), tune their properties and functions, and improve their performance for biomedical studies. The research efforts include exploring new preparation methods, [45,46,69,70,72] investigating nanoparticle formation mechanisms, [120,121] probing nanoparticle photophysics, [47,49,54,122,123] characterizing the fluorescence performance, [48,51,56,58] tuning the emission color, [47,49,71,89] engineering the particle surface, [5658,6466,98,102] encapsulating inorganic materials, [96,97,99,104,105] developing nanoparticle sensors, [52,59,60,62,74,77] imaging cellular structures, [56,57,6366] and in vivo targeting in small animals.

“…47,48 Our current report is one of the few reports where these highly emitting fluorophores have been successfully incorporated into a polymer scaffold in the form of cross-linker and achieved fluorescent polymer beads with intense emission from the nonaggregated chromophore in the solid state. 19,42,49,50 The absolute quantum yield of the powder sample determined using the integrating sphere set up and the fluorescence microscopic images was proof for this. The fact that this approach allows the incorporation of simultaneous addition of multiple fluorophores emitting in different colors makes it very convenient to use for labeling studies where one can access different emission regions just by exciting at the appropriate wavelength without having to label with different fluorophores.…”
