Targeted Delivery of Apoptotic Cell‐Derived Nanovesicles prevents Cardiac Remodeling and Attenuates Cardiac Function Exacerbation

Dextran- and ischemic cardiac homing peptide-conjugated apoptotic cell-derived nanovesicles (ApoNV-DCs) actively target infarcted myocardium and are selectively phagocytosed by macrophages in infarcted heart. ApoNV-DCs polarize macrophages M1 to M2 phenotype and decrease inflammatory responses. Immunomodulation by ApoNV-DCs not only reduce cardiac adverse...

A Self‐Enhancing Nanoreactor Reinforces Radioimmunotherapy by Reprogramming Nutrients and Redox Metabolisms

The Pd/Pt/Au tri-metallic mesoporous nanoparticles (PdPtAu@TF) exhibit high glucose oxidase-, peroxidase-, catalase- and glutathione peroxidase-mimic activities and can function as a self-enhancing nanoreactor to consume glucose and break redox homeostasis in the harsh tumor microenvironment. This study provides a promising strategy to enhance the efficacy...

Histone Deacetylase‐Triggered Self‐Immolative Peptide‐Cytotoxins for Cancer‐Selective Drug Delivery

The facile fabrication of self-immolative peptide-camptothecin nanoassemblies for cancer-selective drug delivery is reported by utilizing the dual-mode peptide targeting design and amine-catalyzed intramolecular hydrolysis. Once the nanoassemblies enter cancer cells, the overexpressed endonuclear histone deacetylases cleave the acetyl group to generate...

Light‐Responsive Programmable Shape‐Memory Soft Actuator Based on Liquid Crystalline Polymer/Polyurethane Network

A light-driven shape memory liquid crystalline network film by covalently cross-linking polyurethane into liquid crystalline polymer networks (PULCN) is realized. The all-optically controlled novel PULCN material enabled the fabrication of artificial muscles and biomimetic devices. Abstract Liquid crystalline polymers (LCPs), especially liquid...

Encapsulating and Operating a Stable Li3ErBr6‐Based Solid Li–SeS2 Battery at Room Temperature

In this study, a new solid-state electrolyte Li3ErBr6 (LErB) is synthesized by a vacuum evaporation-assisted method. LErB has high lithium-ion conductivity, wide electrochemical window, good formability, and good compatibility with electrode materials. Here, the all-solid-state Li–SeS2 batteries based on LErB are assembled by simple cold pressing and...

Functionalized DNA Nanomaterials Targeting Toll‐Like Receptor 4 Prevent Bisphosphonate‐Related Osteonecrosis of the Jaw via Regulating Mitochondrial Homeostasis in Macrophages

Reversal of macrophage polarization imbalance is considered a novel method to prevent bisphosphonate-related osteonecrosis of the jaws (BRONJ). Synthesized tetrahedral DNA nanomaterial (TDN)-modified with TLR4-siRNA (TDN-TLR4-4siR) shows excellent biocompatibility and decreased pro-inflammatory M1 macrophages via reprogramming mitochondrial dynamics...

Main‐Chain Nematic Side‐Chain Smectic Composite Liquid Crystalline Elastomers

The composite liquid crystalline elastomers with the mixed main-chain/side-chain topology, using the siloxane backbone, are developed. It is shown that such composites break into micro-phase separated regions of nematic and smectic order, which leads to much improved mechanical properties of the network. Abstract A composite liquid crystalline...

An Ultrafast, High‐Loading, and Durable Poly(p‐aminoazobenzene)/Reduced Graphene Oxide Composite Electrode for Supercapacitors

Polyaniline-based supercapacitors are limited by poor rate capability, undesirable cycling stability, and low mass-loading. Hence, a novel 3D polyaniline analog-based composite is proposed as a pseudocapacitive electrode. The prepared high-loading electrodes possess abundant stable redox-active sites and porous conductive nanostructure, solving the...

Ligand Exchange Reaction Enables Digital‐To‐Analog Resistive Switching and Artificial Synapse within Metal Nanoparticles

The transition between digital and analog resistive switching is achieved by the ligand exchange reaction of metal nanoparticles. The formation of metallic conducting filaments and coordination bridges accounts for the underlying switching mechanism for digital and analog devices respectively. The analog device is subsequently used to implement synaptic...

p—π Conjugated Polyelectrolytes Toward Universal Electrode Interlayer Materials for Diverse Optoelectronic Devices

By utilizing p–π conjugation to replace the commonly used π–π conjugation, an unprecedented anode interlayer material PCP-S is developed to be universally used in diverse optoelectronic devices, including organic solar cells, perovskite solar cells, and organic light-emitting diodes. Abstract The development of universal interlayer materials...
