Hot Article: Luminescent quantum-dot-sized semiconducting polymer nanspheres

In this ‘Hot’ paper, Mark Green and co-workers from Kings College, London report the synthesis of small luminescent conjugated polymer nanoparticles and the role of poly(ethylene glycol) in the nanoparticle structure.  This is the first time that semiconducting polymer nanospheres (SPNs) on the scale of quantum dots have been made using miniemulsion methods.

Luminescent quantum-dot-sized conjugated polymer nanoparticles—nanoparticle formation in a miniemulsion system

SPNs have been made using miniemulsion methods previously but the resulting materials have been significantly larger than quantum dots.  Quantum dots are desirable as these are the nanomaterial of choice for cell imaging.  The SPNs were characterized by TEM, absorption and emission spectroscopy, they were found to be stable in solution for months and bright and are expected to be effective in various fluorescence applications.
