Nanozyme‐based metabolic regulation triggered by tumor‐specific endogenous stimuli has emerged as a promising therapeutic strategy for tumors. The current efficacy, however, is constrained by the limited concentration of endogenous substrates and the metabolic plasticity of tumors. Consequently, the implementation of efficient metabolic regulation in tumor therapy is urgently needed. Herein, a versatile...
Dual‐Functional Ag@Pt Nanozymes
Two types of dual‐functional Ag@Pt nanozymes, adjustable NA‐Ag@Pt nanozyme and POD‐like enhancing FNA‐Ag@Pt nanozyme, are designed and synthesized by nucleic acid and metal ions coordination‐driven one‐step rapid self‐assembly. One of the Pb‐FNA‐Ag@Pt nanozymes can achieve specific detection of Pb2+ and solve the specificity problem of nanozymes, and both Ag@Pt nanozymes...
Realizing high‐precise and adjustable regulation of engineering nanozyme is important in nanotechnology. Here, Ag@Pt nanozymes with excellent peroxidase‐like and antibacterial effects are designed and synthesized by nucleic acid and metal ions coordination‐driven one‐step rapid self‐assembly. The adjustable NA‐Ag@Pt nanozyme is synthesized within 4 min using single‐stranded nucleic acid as templates,...
Anthropogenic nitrate pollution has an adverse impact on the environment and human health. As part of a sustainable nitrate management strategy, electrochemical denitrification is studied as an innovative strategy for nutrients recycling and recovering. It is, however, challenging to selectively electro‐reduce nitrate with low‐concentration for ammonia. Herein, the photo‐deposition of size‐defined...
With an extremely high theoretical energy density, poly(ethylene oxide) (PEO)‐based solid‐state lithium‐sulfur (Li‐S) batteries are emerging as one of the most feasible and safest battery storage systems. However, the long‐term cycling performance is severely impeded by polysulfides (Li2Sn, n = 4–8) shuttling and terrible electrode passivation from the electronic insulating Li2S. Here, a novel cathode...
Fluorescence (FL) bioimaging in the second near‐infrared window (NIR‐II, 1000–1700 nm) provides improved imaging quality and high resolution for diagnosis of deep‐seated tumors. However, integrating FL bioimaging and photothermal therapy (PTT) in a single photoactive molecule exhibits a great challenge because a dramatic increase of PTT in the NIR‐II window benefitting from the nonradiative decay...
Phase change materials (PCMs) are regarded as promising candidates for realizing zero‐energy thermal management of electronic devices owing to their high thermal storage capacity and stable working temperature. However, PCM‐based thermal management always suffers from the long‐standing challenges of low thermal conductivity and liquid leakage of PCMs. Herein, a dual‐encapsulation strategy to fabricate...
Ordered bio‐inorganic hybridization has evolved for the generation of high‐performance materials in living organisms and inspires novel strategies to design artificial hybrid materials. Virus‐like particles (VLPs) are attracting extensive interest as self‐assembling systems and platforms in the fields of biotechnology and nanotechnology. However, as soft nanomaterials, their structural stability remains...
Lithium–sulfur batteries, as one of promising next‐generation energy storage devices, hold great potential to meet the demands of electric vehicles and grids due to their high specific energy. However, the sluggish kinetics and the inevitable “shuttle effect” severely limit the practical application of this technology. Recently, design of composite cathode with effective catalysts has been reported...
The prospect of programming molecular computing systems to realize complex autonomous tasks has advanced the design of synthetic biochemical logic circuits. One way to implement digital and analog integrated circuits is to use noncovalent hybridization and strand displacement reactions in cell‐free and enzyme‐free nucleic acid systems. To date, DNA‐based circuits involving tens of logic gates capable...
Dynamic DNA structures, a type of DNA construct built using programmable DNA self‐assembly, have the capability to reconfigure their conformations in response to environmental stimulation. A general strategy to design dynamic DNA structures is to integrate reconfigurable elements into conventional static DNA structures that may be assembled from a variety of methods including DNA origami and DNA tiles...
