Macrophages (Mφs) are characterized by remarkable plasticity, an essential component of chronic inflammation. Thus, an appropriate and timely transition from proinflammatory (M1) to anti‐inflammatory (M2) Mφs during wound healing is vital to promoting resolution of acute inflammation and enhancing tissue repair. Herein, exosomes derived from M2‐Mφs (M2‐Exos), which contain putative key regulators...
Composites based on carbon nanotubes (CNTs) are promising patternable materials that can be engineered to incorporate the outstanding properties of CNTs into various applications via printing technologies. However, conventional printing methods for CNTs require further improvement to overcome the major drawbacks that limit the patterning resolution and target substrate. Herein, an intaglio contact...
Device Miniaturization
Intaglio contact printing enables the realization of highly precise carbon nanotube (CNT) network patterns exhibiting multi‐functionalities without restrictions on the substrate. In article number 2106174, Soonmin Seo, Yoon‐Kyu Song, Ju‐Hyung Kim, and co‐workers present this method for the fabrication and miniaturization of high‐performance devices, including flexible fringe‐effect...
Organometallic and all‐inorganic halide perovskites (HPs) have recently emerged as promising candidate materials for resistive switching (RS) nonvolatile memory due to their current–voltage hysteresis caused by fast ion migration. Lead‐free and all‐inorganic HPs have been researched for non‐toxic and environmentally friendly RS memory devices. However, only HP‐based devices with electrochemically...
In article number 2003225, Soo Young Kim, Ho Won Jang, and co‐workers successfully fabricate preconditioned resistive switching memory devices using lead‐free dual‐phase halide perovskites. The devices show filamentary resistive switching behavior involving Ag cations in halide perovskites with ultra‐low operating voltages, and high on/off ratio.
In article number 1802618, Joong‐jae Lee, Hak‐Sung Kim, and co‐workers develop an intracellular protein delivery system by sequence specific DNA‐protein interactions for targeted therapy. Engineered nucleoproteins are sequentially assembled onto the surface of gold nanoparticles. The resulting nucleoprotein nanoparticles exhibit highly programmable designability for functional protein loading, and...
With a growing number of intracellular drug targets and the high efficacy of protein therapeutics, the targeted delivery of active proteins with negligible toxicity is a challenging issue in the field of precision medicine. Herein, a programed assembly of nucleoprotein nanoparticles (NNPs) using DNA and zinc fingers (ZnFs) for targeted protein delivery is presented. Two types of ZnFs with different...
Spatial arrangement of 1D nanomaterials may offer enormous opportunities for advanced electronics and photonics. Moreover, morphological complexity and chemical diversity in the nanoscale components may lead to unique properties that are hardly anticipated in randomly distributed homogeneous nanostructures. Here, controlled chemical segmentation of metal nanowire arrays using block copolymer lithography...
