In nature, many organisms respond chemotactically to external chemical stimuli in order to extract nutrients or avoid danger. Inspired by this natural chemotaxis, micro/nanomotors with chemotactic properties have been developed and applied to study a variety of disease models. This chemotactic strategy has shown promising results and has attracted the attention of an increasing number of researchers...
Potassium‐ion batteries (PIBs) have broad application prospects in the field of electric energy storage systems because of its abundant K reserves, and similar “rocking chair” operating principle as lithium‐ion batteries (LIBs). Aiming to the large volume expansion and sluggish dynamic behavior of anode materials for storing large sized K‐ion, bismuth telluride (Bi2Te3) nanoplates hierarchically encapsulated...
Amination of aryl chlorides by metallaphotocatalysis is highly desired but remains practically challenging. Meanwhile, relying on soluble noble‐metal photocatalysts suffers from resource scarcity and structural instability which limit their practical application. Here in, a highly crystalline acetylene‐based hydrazone‐linked covalent organic framewok‐1 (AC‐COF‐1) is reported that enables metallaphotocatalytic...
As a typical perovskite‐type crystal, polyhedral strontium titanate (SrTiO3) has shown anisotropic charge transport behavior in recent studies, however, the carrier transportation and transition of which has not been explained very clearly. This work present the existence of Sr and O divacancies in the novel rhombicuboctahedron SrTiO3 micro/nano particles (Sr1−xTiO3−x/TiO2−x) with exposing (100),...

Multiple crystal surface exposure gives SrTiO3 micro/nano crystal better photocatalytic performance. In addition to the exposed crystal surface, the vacancy is vitally important. In article number 2202659, Li‐zhu Wu, Dongping Duan, and co‐workers investigate the dynamic formation mechanism of atomic vacancies of SrTiO3 crystal deeply, and more importantly, the Sr‐O di‐vacancies...
The investigation of carbonaceous‐based anode materials will promote the fast application of low‐cost potassium‐ion batteries (PIBs). Here a nitrogen and oxygen co‐doped yolk‐shell carbon sphere (NO‐YS‐CS) is constructed as anode material for K‐ion storage. The novel architecture, featuring with developed porous structure and high surface specific area, is beneficial to achieving excellent electrochemical...
Engineered platelets (PLT) can bring new possibilities for diseases treatment due to the specific response for a variety of physiological disease environments. However, the deep penetration of engineered PLT in diseased tissues such as tumor is still an important challenge that restricts the therapeutic effect. Herein, the engineered PLT micromotor (PLT@PDA‐DOX) is constructed by a universal self‐polymerization...
In the preparation of nanomaterials, the kinetics and thermodynamics in the reaction can significantly affect the structures and phases of nanocrystals. Therefore, people are keen to adopt various synthetic strategies to accurately assemble the target nanocrystals, and reveal the underlying mechanism of the formation of specific structures. In this work, the total reaction time is adjusted to let...
Infection with live‐attenuated vaccines always inevitably induces side effects that reduce their safety. This study suggests a concept of magnetic virus produced by genetically modifying viral surfaces with Fe3O4 nanoparticles (NPs) to control their tropisms. An iron‐affinity peptide is designed to be displayed on the viral surface protein (VP1) of human enterovirus type 71 (EV71), a typical nonenveloped...
Cancer biomarkers are expected to be indicative of the occurrence of certain cancer diseases before the tumors form and metastasize. However, many biomarkers can only be acquired in extremely low concentrations, which are often beyond the limit of detection (LOD) of current instruments and technologies. A practical strategy for nanopore sensing of cancer biomarkers in raw human blood down to the femtomolar...
In article number 1804078, Hai‐Chen Wu and co‐workers develop a strategy for the ultrasensitive detection of cancer biomarkers based on the combination of a sandwich assay, “click” chemistry, and DNA‐assisted nanopore sensing. The limit of detection of the strategy can be as low as the femtomolar level. Furthermore, it can effectively eliminate interferences from plasma proteins and be applied in...
Multifunctional nanotheranostic agents are of particular importance in the field of precise nanomedicine. However, a critical challenge remains in the rational fabrication of monodisperse multicomponent nanoparticles with enhanced multifunctional characteristics for efficient cancer theranostics. Here, a rational and facile synthesis of monodisperse Gd2O3/Bi2S3 hybrid nanodots (Gd/Bi‐NDs) is demonstrated...
Enrichment of molecular photosensitizers and catalysts in a confined nanospace is conducive for photocatalytic reactions due to improved photoexcited electron transfer from photosensitizers to catalysts. Herein, the self‐assembly of a highly stable 3D supramolecular organic framework from a rigid bipyridine‐derived tetrahedral monomer and cucurbit[8]uril in water, and its efficient and simultaneous...
