Magnetic conjugated polymer nanoparticles doped with a europium complex for biomedical imaging

Self-assembling conjugated polymer nanoparticles containing PVK and PLGA-PEG as a matrix polymer were doped with both a luminescent rare-earth complex and magnetic nanoparticles (SPIONs), giving rise to materials that are both luminescent and magnetic.

The Biosynthesis of Infrared-Emitting Quantum Dots in Allium Fistulosum

The development of simple routes to emissive solid-state materials is of paramount interest, and in this report we describe the biosynthesis of infrared emitting quantum dots in a living plant via a mutual antagonistic reaction. Exposure of common Allium fistulosum to mercury and tellurium salts under ambient conditions resulted in the expulsion of crystalline, non-passivated HgTe quantum dots that exhibited emissive characteristics in the near-infrared spectral region, a wavelength range that is important in telecommunications and solar energy conversion.

Red-emitting protein-coated conjugated polymer nanoparticles

Red emitting materials are desirable in biology due to the transparency of certain biological tissues at these wavelengths.
