Resistive SwitchingOn page 2715, physically transient resistive switching memory based on silk fi broin is demonstrated by Y. Hao, X. Chen, and co-workers.The memory devices can be absolutely dissolved in deionized water or phosphate-buffered saline in 2 hours.The transient devices have the potential for application in secure data storage systems and biocompatible electronics. Electron MicroscopyIn situ liquid cell scanning transmission electron microscopy is a powerful tool to study the formation of nanostructures in real time.On page 2701, S. E. Skrabalak and co-authors demonstrate the dendritic growth of palladium on nanocubic gold seeds, which is perturbed by growth of palladium dendrites that are immobilized on the silicon nitride membranes. DNA-Based BiosensorsDNA-based biosensors are cost-effective, sensitive and show promise as point-of-care diagnostic tools.DNA is an ideal molecule for sensing not only because of its specifi city and controllability but also because of its robustness and ability to function under a wide range of biologically relevant temperatures and conditions.On page 2689,
