Methods for the preparation and microscopic study of Nanogold® and Undecagold-labeled nucleic acids, as well as their applications in building nanostructured materials and nanodevices, are discussed in our recent paper in Micron:
Powell, R. D., and Hainfeld, J. F.: Preparation and high-resolution microscopy of gold cluster labeled nucleic acid conjugates and nanodevices. Micron, 42, 163-174 (2011).

Check our expanded online library of applications – we have added two papers presented at the Microscopy & Microanalysis 2010 meeting:
- Large Covalently Linked Fluorescent and Gold Nanoparticle Immunoprobes
Using FluoroNanogold™ with larger gold nanoparticles. This study presents some new results.
- Gold Labeling of Protein Fusion Tags for EM
New results using 5 nm Ni-NTA-Nanogold, and other investigations into new expression tags.
When it comes to gold nanoparticles, slightly bigger is often better — especially if you want plasmonic or electronic properties that only kick in for particles bigger than Nanogold®. We are developing larger gold nanoparticle labels with the same specific, controlled covalent reactivity as Nanogold®; we have already presented preliminary results with 3 nm Nanogold® particles and 10 nm Nanogold® particles, and we are planning a new product line soon.
