Thesis Top Lessons from before and after nanotech   pp611 - 612 Chris Toumey doi:10.1038/nnano.2012.173 Ethical questions arising from biotechnology first, then nanotechnology, and synthetic biology now, present common features, but as Chris Toumey explains, the scientific and ethical issues arising in each case should be treated individually. Research Highlights Top Our choice from the recent literature   p613 doi:10.1038/nnano.2012.181 News and Views Top Nanoparticles: Imaging electrocatalysts in action   pp615 - 616 Stephen J. Percival and Bo Zhang doi:10.1038/nnano.2012.164 A surface plasmon resonance imaging technique can be used to probe electrocatalytic reactions occurring on individual nanoparticles. See also: Letter by Shan et al. Single molecules: A protein in the spotlight   pp616 - 617 Nicolas Plumeré doi:10.1038/nnano.2012.175 The photocurrent of a single photosynthetic protein can be measured by using a scanning probe tip as both an electrode and a localized light source. See also: Letter by Gerster et al. Quantum information: Blockade at a different level   pp617 - 619 Guido Burkard doi:10.1038/nnano.2012.174 Valley degeneracy in carbon nanostructures can be detrimental to electron spin control and readout based on spin blockade. As a way around this problem, it is now shown how to use a combined valley–spin blockade instead. See also: Letter by Pei et al.
