The prevalence of drug‐resistant bacteria presents a significant challenge to the antibiotic treatment of Helicobacter pylori (H. pylori), while traditional antimicrobial agents often suffer from shortcomings such as poor gastric retention, inadequate alleviation of inflammation, and significant adverse effects on the gut microbiota. Here, a selenized chitosan (CS‐Se) modified bismuth‐based metal‐organic...
Dielectric energy storage polymers play a vital role in advanced electronics and electrical systems, due to their high breakdown strength, excellent reliability, and easy fabrication. However, the low dielectric constant and poor thermal resistance of dielectric polymers limit their energy storage density and working temperatures, making them less versatile for broader applications. In this work,...
Intracellular bacterial pathogens hiding in host cells tolerate the innate immune system and high‐dose antibiotics, resulting in recurrent infections that are difficult to treat. Herein, a homing missile‐like nanotherapeutic (FeSAs@Sa.M) composed of a single‐atom iron nanozyme (FeSAs) core coated with infected macrophage membrane (Sa.M) is developed for in situ elimination of intracellular methicillin‐resistant...
The proper functioning of host defense system (HDS) is the key to combating bacterial infection in biological organisms. However, the delicate HDS may be dysfunctional or dysregulated, resulting in persistent infection, tissue damage, or delayed wound healing. Herein, a powerful artificial “host defense system” (aHDS) is designed and constructed for treatment of bacterial infections. First, the aHDS...
Cobalt‐based electrodes receive emerging attention for their high theoretical capacity and rich valence variation ability, but state‐of‐the‐art cobalt‐based electrodes present performance far below the theoretical value. Herein, the in‐depth reaction mechanisms in the alkaline electrolyte are challenged and proven to be prone to the surface‐redox pseudocapacitor behavior due to the low adsorption...
Metallic bismuth (Bi) holds great promise in efficient conversion of carbon dioxide (CO2) into formate, yet the complicated synthetic routes and unobtrusive performance hinder the practical application. Herein, a facile galvanic‐cell deposition method is proposed for the rapid and one‐step synthesis of Bi nanodendrites. Compared to the traditional deposition method, it is found that the special galvanic‐cell...
Triple‐cation mixed‐halide perovskites have attracted considerable attention due to their excellent photovoltaic properties and enhanced stability, though the power conversion efficiency (PCE) is still far below the theoretical expectation. In order to understand the microscopic mechanisms responsible for the gap, a Cs0.05(FA0.85MA0.15)0.95Pb(I0.85Br0.15)3 (CsFAMA)‐based solar cell with respectful...
Chronic wound healing is an important and basic issue in medical and healthcare fields. Recently, stimuli‐responsive hydrogel systems have emerged as promising drug delivery carriers for wound management. However, given to the limited therapeutic outcomes, new hydrogel systems for efficient wound treatment are urgently needed. Here, the development of a 2D MXene‐based hydrogel system for highly efficient...
Bornite (Cu5FeS4) is an Earth‐abundant, nontoxic thermoelectric material. Herein, twin engineering and Se alloying are combined in order to further improve its thermoelectric performance. Cu5FeS4−xSex (0 ≤x≤ 0.4) icosahedral nanoparticles, containing high‐density twin boundaries, have been synthesized by a colloidal method. Spark plasma sintering retains twin boundaries in the pellets sintered from...
Pyro‐phototronic and piezo‐phototronic effect have shown their important roles for high performance heterojunction‐based photodetectors (PDs). Here, a coupling effect of pyro‐phototronic and piezo‐phototronic effect is utilized to fabricate a self‐powered and broadband PD based on the MAPbI3 single‐crystal film/n‐Si heterojunction. First, by using the pyro‐phototronic effect derived from MAPbI3, the...
Structural color hydrogels are promising candidates as scaffold materials for tissue engineering and for matrix cell culture and manipulation, while their super‐elastic features are still lacking due to the irreconcilable interfere of the precursor and the self‐assembly unit. This hinders many of their practical biomedical applications where elasticity is required. Herein, hydrophilic and size‐controllable...
Conductive hydrogels are receiving increasing attention for their utility in electronic area applications requiring flexible conductors. Here, it is presented novel conductive hydrogel microfibers with alginate shells and poly (3, 4‐ethylenedioxythiophene): poly (4‐styrenesulfonate) (PEDOT: PSS) cores fabricated using a multiflow capillary microfluidic spinning approach. Based on multiflow microfluidics,...
In article number 1803551, Zhiyang Li, Xuehao Wang, Yuanjin Zhao, and co‐workers present mussel‐inspired photonic crystal (PhC) barcodes with graphene oxide (GO) encapsulation for multiplex miRNA detection. The GO‐based hybridization chain reaction strategy realizes low abundance and high sensitivity miRNA quantification. At the same time, multiplex detection is achieved by employing different GO‐decorated...
Multiplexed microRNA (miRNA) quantification has a demonstrated value in clinical diagnosis. In this paper, novel mussel‐inspired photonic crystal (PhC) barcodes with graphene oxide (GO) encapsulation for multiplexed miRNA detection are presented. Using the excellent adhesion capability of polydopamine, the dispersed GO particles can be immobilized on the surfaces of the PhC barcodes to form an additional...
Significant progress is achieved for the utilization of graphene quantum dots as enzyme mimics in various biomedical fields recently. Although promising, the biocatalytic performance is far from satisfactory. Here, the rational design and synthesis of specific oxygenated groups enriched graphene quantum dots (o‐GQDs) via a facile oxidation reflux route is reported. These well‐prepared o‐GQDs with...
