When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration — something that is still not fully understood. Now, an international team led by researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has directly observed how the protein shells of viruses can change shape during dehydration, offering new clues to viral resilience and opening new possibilities for virology research. The results, published in Light: Science & Applications, lay the groundwork for potential applications in virology and public health, and can for instance help develop antiviral strategies. more

Plasmons promise a variety of applications if the processes triggered by optical excitation in the nanoparticles can be controlled. A research team from Hamburg and Berlin reports in Nano Letters experimental observations that cannot be explained by established models and describes a new theoretical model that explains the dynamics of excited gold nanoparticles observed in experiments. more

An international team of scientists, led by Kartik Ayyer from the MPSD, has obtained some of the sharpest possible 3D images of gold nanoparticles. The resuts lay the foundation for obtaining high resolution images of macromolecules. more

Research group leader Kartik Ayyer has conceived a new method to image much smaller biomolecules at an unprecedented  resolution. It involves new algorithms as well as  2D crystals or gold, as he describes in his paper in Optica. more
