Bart Hoogenboom, 2012 First visualisation of the DNA double helix in water: A miniaturised cantilever tracing the contours of the DNA double helix, with its deflection detected by laser optics (not to scale). Atomic Force Microscopy with Nanoscale Cantilevers Resolves Different Structural Conformations of the DNA Double Helix (Nano Letters, ACS, June 2012) |

Nguyen TK Thanh, 2001 This image was captured using Transmission Electron Microscope (TEM) at 8000 times magnification during the work on the immuno-aggregation assay based on protein coated gold nanoparticles. The whole flower containing few tens of billion of gold nanoparticles aggregated due to specific interaction between protein A and anti-protein A (Nguyen TK Thanh and Zeev Rosenzweig, Anal Chem, 2002, 74, 1624). |

John Finney Ice XIII is one of the newly-discovered ice phases - the water-methanol picture shows how the methanol molecules (grey) and the water molecules (yellow) microsegregate, an effect which can quantitatively and simply explain the hydrophobic interaction that is central to much of biology (and chemistry). |
