Biosynthesis of luminescent quantum dots in an earthworm

Klaus Suhling and his groups’ contribution is the characterization of the fluorescence of the quantum dots obtained from the worms, i.e. to measure the fluorescence spectra, quantum yield and fluorescence lifetime. This contribution is an essential piece in the jigsaw to ascertain that the bio-synthesised quantum dots actually fluoresce, once they have been identified by x-ray diffraction and electron microscopy. Since fluorescence was successfully established by my contribution, we could then proceed to functionalise the quantum dots and use them in cell imaging, thus demonstrating the usefulness of bio-synthesised quantum dots for fluorescence imaging.
