Over the past decade, liquid-phase electron microscopy has revolutionized direct mechanistic studies of reactions in liquid media. Scanning electron microscopy and (scanning) transmission electron microscopy of liquid samples have enabled breakthroughs in nanoparticle chemistry, soft-matter science, catalysis, electrochemistry, battery research and biochemistry. See Kashin et al.

  • The ability of soft nanoparticles to shrink makes their diffusion in a confined environment faster than that of hard nanoparticles of the same size. The size reduction results from electrostatic interactions between the soft nanoparticle and medium and has important implications for their use as efficient drug carriers.

  • The propensity of guanine and its derivatives to assemble into guanine quartets makes them a privileged tool in the design of functional supramolecular assemblies. This Review describes the production of such functional suprastructures and their applications in nanotechnology, soft matter and chemical biology.
