      DNA origami nanostructures can be coated with well-defined protein–dendron conjugates. Plain DNA origami nanostructures often suffer from poor delivery properties, stability, and immunogenicity in biological systems. Coating of the origami with inert proteins (e.g., serum albumin) can, however, alleviate these issues efficiently.

      Externally actuated ferrogels are used to demonstrate the importance of timing of biologic therapies with respect to injury-induced inflammation. Delaying treatment until the peak of inflammation leads to both early and long-term regenerative benefits surpassing those seen with treatment initiated at the time of injury. This strategy can likely be applied broadly to both new and existing cell transplantation therapies.

      Cotransporting ion, Na+, is found as a trigger for the proceeding of l-carnitine-conjugated poly(lactic-co-glycolic acid) (PLGA) nanoparticles (LC-PLGA NPs) targeting to Na+-coupled organic cation/carnitine transporter 2 (OCTN2). In this case, LC-PLGA NPs and Na+ bind to specific binding sites of OCTN2, and then initiate the conformation change from outward-facing to occluded state to form an energetically stable intermediate complex (OCTN2-Na+-LC-PLGA NPs). The complex induces membrane invagination and the following endocytosis.

      Cell-engineered nanovesicles (CNVs) fabricated from feeder cells successfully regulate the fates of embryonic stem cells through contact-dependent stimulus. Unlike feeder layer methods, scalable, diffusible, and storable characteristics of CNVs can constitute a novel tool for embryonic stem cell research. The CNV method might be used in various other applications that require heterotipic cell–cell interactions.
