A polypeptide-DNA hydrogel is prepared by Z. Li, D. Liu, and co-workers, employing the “X”-shaped DNA assembling structure as crosslinker. The hydrogel can be modified with multifunctional components (here fluorescent molecules as a model), and possess excellent self-healing and thixotropic properties, enabling the direct-writing of arbitrary 3D structures. The study on page 1138 provides a simple, universal strategy for the assembly of functionalized hydrogels with biomolecules, especially enzymes.

Nanoparticles have recently been widely applied in biomedicine. Understanding how nanoparticles interact with biosystems (especially cells) is crucial for their further biomedical application. On page 1055, H.-m. Ding and Y.-q. Ma summarize the current progress on theoretical and computational investigations of nanoparticle-biomembrane interactions in cellular delivery. The parameters that determine the cellular uptake and subsequent intracellular trafficking of nanoparticles are discussed in detail.

A method to encapsulate magnetic nanoparticles into His-tagged virus-like particles (VLPs) is developed by L. Ren and co-workers on page 1190. It is the first report using the affinity of histidine tags for the nickel-nitrilotriacetic acid chelate to trigger encapsulation of nanoparticles by VLPs. This makes it possible to integrate a wide range of starting nanoparticles into fundamentally different kinds of viral coating proteins or other nonenveloped viruses for application in cancer nanotechnology and medicine.

The gecko's foot generates an adhesive force with numerous keratinous setae which form a large real contact area with the substrate. While geckos can switch the adhesion freely, the detachment of gecko-inspired synthetic adhesives is often difficult, and relies on external mechanical control. On page 1131, D. Wang, S. N. Gorb, F. Zhou, and co-workers develop chemically responsive nanofibrillar surfaces: silicon nanowires grafted with polymers, in which attachment and detachment are chemically triggered in response to pH, humidity, or electrolyte solution.
