Heme enzymes, with the pentacoordinate heme iron active sites, possess high catalytic activity and selectivity in biosensing applications. However, they are still subject to limited catalytic stability in the complex environment and high cost for broad applications in electrochemical sensing. It is meaningful to develop a novel substitute that has a similar structure to some heme enzymes and mimics...
Future applications of conjugated polymer particles (CPP) in medicine, organic photonics, and optoelectronics greatly depend on high performance and precisely adjustable optical properties of the particles. To meet these criteria, current particle systems often combine conjugated polymers with inorganic particles in core–shell geometries, extending the possible optical characteristics of CPP. However,...
The application of static or precessing magnetic fields on superparamagnetic colloids confined at fluid interfaces induces the formation of different self‐assembled structures, mainly determined by the field tilt angle. In article number 2101188, Fernando Martínez‐Pedrero, Carles Calero, and co‐workers demonstrate that dynamic bead‐like structures composed of spinning particles can be used in the...
In article number 2101483, Kostas Kostarelos, Açelya Yilmazer, and co‐workers report that thin, biological‐grade graphene oxide (GO) nanosheets show molecular affinity toward the SARS‐CoV‐2 viral spike and the ACE2‐bound spike complex. GO nanosheets were shown to inhibit the infection of wild‐type SARS‐CoV‐2 experimentally in cell cultures. Through an interplay of molecular dynamics simulations and...
In article number 2101655, Kelong Fan, Zhanguo Li, Xiyun Yan, and co‐workers develop a highly sensitive platform for diagnosis of autoimmune disease. The antigen and anti‐Fc peptides are displayed on the surface of ferritin to construct nanocage‐based capture‐detection system. Multimeric display significantly enhances their binding ability to corresponding antibodies, thus improving the detection...
Protein therapy has the potential to revolutionize medicine, but the delivery of multiple proteins is challenging because it requires the development of a strategy that enables different proteins to be combined together and transported not only into cells, but also to the desired cell compartments, such as the nucleus. Here, an efficient intranuclear protein delivery nanoplatform based on modified...
A new strategy for retaining long‐range order during ligand exchange of nanocrystal superlattices is used to construct PbSe infrared photodetectors by Christine Orme and co‐workers (article number 2101166). The ordered photodetectors have a 16× higher responsivity and 2× faster response time compared to disordered ones.
The detection of autoantibodies is critical for diagnosis of autoimmune diseases. However, the sensitivity is often limited by the properties of the antigens and the detection systems such as enzyme‐linked immunosorbent assay (ELISA). Here, employing the multidisplay ability of ferritin, a highly sensitive nanocage‐based capture‐detection system is designed, of which the sensitivity is 100–1000‐fold...
Aqueous zinc‐ion batteries (AZIBs) are regarded as one of the most promising alternative technology to lithium‐ion batteries on account of their low flammability and cost‐benefits. Among various cathode materials in AZIBs, environment‐friendly and sustainable organic electrode materials stand out owing to their structural diversity and tunability. However, their limited rate capability and cycle stability...
Magnetic colloids adsorbed at a fluid interface are unique model systems to understand self‐assembly in confined environments, both in equilibrium and out of equilibrium, with important potential applications. In this work the pearl‐chain‐like self‐assembled structures of superparamagnetic colloids confined to a fluid–fluid interface under static and time‐dependent actuations are investigated. On...
In article number 2100956, Haitao Zhang, Weiqing Yang, Jun Chen, and co‐workers invent a low‐cost, scalable, and air‐stable conducting polymer ink via a facile assemble‐disperse strategy for printed micro‐supercapacitors, which exhibits remarkable energy storage capacity as a power source for wearable bioelectronics in the era of Internet of Things.
Interfacial engineering methods have been developed to solve defect issues of perovskite solar cells (PSCs). However, traditional surface passivation has limited effects on eliminating defect‐forming residuals, while secondary grain growth (SGG) is restricted by limited choices of additives and intrinsic properties of perovskites. Here, a pincer strategy of taking advantages of surface passivation...
Despite the rapid development of CsPbIxBr3−x (0 ≤ x ≤ 3) inorganic perovskite solar cells, associated with their superior thermal stability, their low moisture stability limits their commercial deployment. In this study, 1D‐2D‐3D multidimensional coupled perovskites are prepared by means of an in situ self‐integration approach. This pioneering method allows incorporating thus far unreported 1D‐Tpy...
Solid state nanopores are single‐molecular devices governed by nanoscale physics with a broad potential for technological applications. However, the control of translocation speed in these systems is still limited. Ionic liquids are molten salts which are commonly used as alternate solvents enabling the regulation of the chemical and physical interactions on solid–liquid interfaces. While their combination...
Manipulations of carrier and phonon scatterings through hierarchical structures have been proved to be effective in improving thermoelectric performance. Previous efforts in GeTe‐based materials mainly focus on simultaneously optimizing the carrier concentration and band structure. In this work, a synergistic strategy to tailor thermal and electrical transport properties of GeTe by combination with...
Self‐assembled block copolymers are promising templates for fabricating thin film materials with tuned periodic feature sizes and geometry at the nanoscale. Here, a series of nanostructured platinum and iridium oxide electrocatalysts templated from poly(styrene)‐block‐poly(vinyl pyridine) (PSbPVP) block copolymers via an incipient wetness impregnation (IWI) pathway is reported. Both nanowire and nanocylinder...
Organic–inorganic halide perovskite solar cells (PSCs) have shown a significant growth in power conversion efficiencies (PCEs) during last decade. Progress in device architecture and high‐quality perovskite film fabrication has led to an incredible efficiency over 25% in close to a decade. Developments in solution‐based thin film deposition techniques for perovskite layer preparation in PSCs provide...
Carbonaceous materials exhibit promising application in electrochemical energy storage especially for hollow or porous structure due to the fascinating and outstanding properties. Although there has been achieved good progress, controllable synthesis of hollow or porous carbons with uniform morphology by a green and easy way is still a challenge. Herein, a new artful and green approach is designed...
The tumor hypoxic microenvironment not only induces genetic and epigenetic changes in tumor cells, immature vessels formation for oxygen demand, but also compromises the efficiency of therapeutic interventions. On the other hand, conventional therapeutic approaches which kill tumor cells or destroy tumor blood vessels to block nutrition and oxygen supply usually facilitate even harsher microenvironment...
