Infection classification is the key for choosing the proper treatment plans. Early determination of the causative agents is critical for disease control. Host responses analysis can detect variform and sensitive host inflammatory responses to ascertain the presence and type of the infection. However, traditional host‐derived inflammatory indicators are insufficient for clinical infection classification...
Compartmented Bienzyme Biocatalysts
Biomimetic mineralization and slow seed‐induced nucleation strategy enables the synthesis of compartmented bienzyme system based on core‐shell ZIF@ZIF in aqueous solution. Bienzyme can be accurately localized into the shell and core with uniform distribution. The optimization of pore structure and bienzyme positional assembly provides a guidance for preparing efficient...
Transient batteries are expected to lessen the inherent environmental impact of traditional batteries that rely on toxic and critical raw materials. This work presents the bottom‐up design of a fully transient Zn‐ion battery (ZIB) made of nontoxic and earth‐abundant elements, including a novel hydrogel electrolyte prepared by cross‐linking agarose and carboxymethyl cellulose. Facilitated by a high...
Most nanozymes in development for medical applications only exhibit single‐enzyme‐like activity, and are thus limited by insufficient catalytic activity and dysfunctionality in complex pathological microenvironments. To overcome the impediments of limited substrate availabilities and concentrations, some metal‐based nanozymes may mimic two or more activities of natural enzymes to catalyze cascade...
Alginate Hydrogel Microbeads
In article number 2204139, Hiroaki Onoe and co‐workers present near‐infrared (NIR) triggered on‐demand adeno‐associated virus (AAV) release from alginate microbeads with heat transducer for gene therapy. The heat transducer encapsulated in microbeads generate heat under NIR‐irradiation. Subsequently, AAV release from the microbeads could be controlled on‐demand by the...
Percutaneous implants may experience infection for several times during their servicing periods. They need antibacterial activity and durability to reduce recurrent infection and cytocompatibility to reconstruct biosealing. A novel photoresponse bio‐heterojunction (PCT) is developed herein. It consists of TiO2 nanotubes loaded with CuS nanoparticles and wrapped with polydopamine (PDA) layer. In PCT,...
For complex cascade biocatalysis, multienzyme compartmentalization helps to optimize substrate transport channels and promote the orderly and tunable progress of step reactions. Herein, a simple and general synthesis strategy is proposed for the construction of a multienzyme biocatalyst by compartmentalizing glucose oxidase and horseradish peroxidase (GOx and HRP) within core–shell zeolite imidazole...
Accurate detection of trace biomarkers in biological samples is a key task in diagnostic testing, but it remains challenging due to the high concentration of other physiologically relevant interferences. This work presents a new electrochemiluminescence (ECL) sensing device based on a bio‐inspired nanochannel membrane (NM) guarded with two differential gates. The recognition event at the aptamer gate...
Carbon quantum dots (CDs) are a class of emerging carbonaceous nanomaterials that have received considerable attention due to their excellent fluorescent properties, extremely small size, ability to penetrate cells and tissues, ease of synthesis, surface modification, low cytotoxicity, and superior water dispersion. In light of these properties, CDs are extensively investigated as candidates for bioimaging...
Advanced carbon materials are constantly being used in the field of microwave absorption. Herein, in order to enrich the variety and expand the application fields of graphdiyne (GDY), the wrinkled graphene (RGO) nanosheet coated and embedded with GDY porous microspheres (RGO/GDY) are prepared by GDY synthesis, ultrasonic spray, and pyrolysis. The study finds that RGO and GDY have effective synergistic...
Targeted liposomes, as a promising carrier, have received tremendous attention in COVID‐19 vaccines, molecular imaging, and cancer treatment, due to their enhanced cellular uptake and payload accumulation at target sites. However, the conventional methods for preparing targeted liposomes still suffer from limitations, including complex operation, time‐consuming, and poor reproducibility. Herein, a...
Block copolymer (BCP) self‐assembly in thin films is an elegant method to generate nanometric features with tunable geometrical configurations. By combining directed assembly and hybridization methods, advances in nano‐manufacturing have been attested over the past decades with flagship applications in lithography and optics. Nevertheless, the range of geometrical configurations is limited by the...
Gene therapy using adeno‐associated virus (AAV) has potential as a radical treatment modality for genetic diseases such as sensorineural deafness. To establish clinical applications, it is necessary to avoid immune response to AAV by controlled release system of AAV. Here, a near‐infrared (NIR)‐triggered on‐demand AAV release system using alginate hydrogel microbeads with a heat transducer is proposed...
Achieving satisfactory organic pollutant oxidation with a low concentration of peroxymonosulfate (PMS) is vital for persulfate‐involved advanced oxidation processes to reduce resource consumption and avoid excessive sulfate anion (SO42−) production. Herein, efficient conversion of dissolved oxygen (DO) over single‐atomic Fe–N3O1 sites anchored on carbon nitride for efficient contaminant degradation...
A mechanochromic strain sensor that is capable of distinguishing the orientation, the location, and the degree of deformation based on the highly stretchable membrane of main‐chain chiral liquid crystalline elastomer (MCLCE) is proposed. The MCLCE film is designed to exhibit uniform and significant color shift upon the small strain by using step‐growth polymerization of liquid crystal (LC) oligomer...
Poor stability of CsPbBr3 perovskite nanocrystals (NCs) to moisture/heat/light has significantly limited their application as a green phosphor, despite their outstanding luminescent properties. Here, a remarkably stable CsPbBr3 NCs−silica composite phosphor functionalized with surface phenyl molecules (CsPbBr3−SiO2Ph) is synthesized by controlling low‐temperature hydrolysis and condensation reaction...
Potassium‐ion batteries (PIBs) have become one of the promising candidates for electrochemical energy storage that can provide low‐cost and high‐performance advantages. The poor cyclability and rate capability of PIBs are due to the intensive structural change of electrode materials during battery operation. Carbon‐based materials as anodes have been successfully commercialized in lithium‐ and sodium‐ion...
