It has been widely reported that "naked" gold nanoparticles (Au NPs) without protectors have glucose oxidase (GOx)-like activity, and the use of can inhibit GOx-like activity. Here, "non-naked" Au NPs with activity are synthesized by using protein as protector. Although peroxidase-like optimal pH ranges both activities obviously different. Fortunately, as-synthesized show dual enzyme-like at same pH. So, be described "tandem nanozyme." As another bonus, participation protector stabilize make...

Abstract Given the promising prospect of peroxidase‐like nanozymes in colorimetric assay, it is interesting and significant to eliminate their oxidase‐like activities color interference for nanozyme‐based assay. Here, enzyme‐mimicking activity GeO 2 nanomaterials discovered. exclusively possess without characteristics, freeing corresponding assay system from O interference. Moreover, are white, thereby eliminating themselves nanozymes‐based Interestingly, compared with other metal oxides,...

A colorimetric assay based on an enzyme-inhibition strategy is promising for the on-site detection of pesticide residues. Due to high cost and low stability enzymes, nanozymes (nanomaterials with enzyme-like activities) are widely developed as substitutes enzymes. However, inhibition pesticides toward enzymes generally lacks selectivity. It great significance challenge design a specific activity-inhibition strategy. Here, we discovered that iridium nanoparticles possess both peroxidase-like...

Transition-metal dichalcogenide $1T\text{\ensuremath{-}}{\mathrm{VSe}}_{2}$ experimentally exhibits multiple charge density wave (CDW) orders, but its origin is still under debate. Using first-principles calculations, we investigate the of CDW orders in and clarify ground state freestanding monolayer. Our results show that both Fermi-surface nesting electron-phonon coupling account for $4\ifmmode\times\else\texttimes\fi{}4\ifmmode\times\else\texttimes\fi{}3$ superstructure bulk...

Abstract Recently, a new magnetic phase called altermagnetism has been proposed, ushering in third distinct beyond ferromagnetism and antiferromagnetism. It is expected that this groundbreaking exhibits unique physical properties such as C-paired spin-valley locking, anomalous Hall effect, nontrivial Berry phase, giant magnetoresistance. Among all the predicted candidates, several room temperature altermagnets are suggested to host significant potential applications. Nevertheless, direct...

Oxidative stress after ischemia reperfusion can cause irreversible brain damage. Thus, it is vital to timely consume excessive reactive oxygen species (ROS) and conduct molecular imaging monitoring on the injury site. However, previous studies have focused how scavenge ROS while ignoring mechanism of relieving injury. Herein, we reported a layered double hydroxide (LDH)-based nanozyme (denoted as ALDzyme), which was fabricated by confinement astaxanthin (AST) with LDH. This ALDzyme mimic...

Abstract The hollow structure has long attracted great attention because of its excellent properties. However, this special is usually synthesized through some complex approaches. Herein, we discovered that denatured bovine serum albumin (BSA) can trigger unusual biomineralization for the simple, green and shape‐controllable synthesis germanium oxide (GeOx) microsphere (HMS). At high temperature (60°C), BSA was denatured, a compact layer formed around H 2 bubbles. stable suitable anchoring...

Exploring the topological surface state of a semimetal by transport technique has always been big challenge because overwhelming contribution bulk state. In this work, we perform systematic angular-dependent magnetotransport measurements and electronic band calculations on SnTaS2 crystals, layered nodal-line semimetal. Distinct Shubnikov–de Haas quantum oscillations were observed only in nanoflakes when thickness was below about 110 nm, oscillation amplitudes increased significantly with...

<title>Abstract</title> <bold>As a special type of collinear antiferromagnetism (AFM), altermagnetism has garnered significant research interest recently. Altermagnets exhibit broken parity-time symmetry and zero net magnetization in real space, leading to substantial band splitting momentum space even the absence spin-orbit coupling. Meanwhile, breaking always induce nontrivial topology such as Weyl nodes. While semimetal states nodal lines have been theoretically proposed altermagnets,...
