Abstract Nanoscale plasmonic assemblies display exceptionally strong chiral optical activity. So far, their structural design was primarily driven by challenges related to metamaterials whose practical applications are remote. Here we demonstrate that gold nanorods assembled the polymerase chain reaction into DNA-bridged systems have promising analytical applications. The chiroplasmonic activity of side-by-side patterns is attributed a 7–9 degree twist between nanorod axes. This results in...
Reactive oxygen species (ROS) are generated and consumed in living organism for normal metabolism. Paradoxically, the overproduction and/or mismanagement of ROS have been involved pathogenesis progression various human diseases. Here, we reported a two-dimensional (2D) vanadium carbide (V2C) MXene nanoenzyme (MXenzyme) that can mimic up to six naturally-occurring enzymes, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), glutathione (GPx), thiol (TPx) haloperoxidase...
Nanocatalytic medicine has been developed recently to trigger intratumoral generation of highly toxic reactive oxygen species (ROS) for cancer therapy, which, unfortunately, suffers from compromised therapeutic efficacy due a self-protective mechanism, autophagy, cells mitigate oxidative damage. In this work, during the efforts ROS by nanocatalytic medicine, pharmacological autophagy inhibition strategy is implemented augmenting ROS-induced damage synergetic therapy. An iron-containing...
Abstract The explosion of emerging high‐performance 2D MXenes in theranostic nanomedicine is still at the preliminary stage. Despite tremendous efforts devoted to photonic tumor hyperthermia, current photothermal‐conversion nanoagents suffer from critical issues preventing further clinical translation such as low biodegradability. Here, for first time, construction novel molybdenum carbide (Mo 2 C) hyperthermia reported. structure both bulk Mo Ga C ceramic and MXene fully revealed....
Atherosclerosis, driven by chronic inflammation in the artery walls, underlies several severe cardiovascular diseases. However, currently available anti-inflammatory-based strategies for atherosclerosis treatment suffer from compromised therapeutic efficacy and undesirable outcome. Herein, a distinct tetrapod needle-like PdH nanozyme was designed engineered efficient combinatorial reactive oxygen species (ROS) scavenging, hydrogen anti-inflammation, autophagy activation. After loading into...
The anticancer mechanism of nanozymes is dominantly associated with the capacity for generation reactive oxygen species (ROS) caused by valence change metal elements. However, very little research focused on and has achieved exploration development enzyme-mimicking activities valence-invariable compounds. Herein, a distinct calcium fluoride (CaF2 ) nanozyme ultrasound (US)-enhanced peroxidase (POD)-mimicking activity rationally designed engineered efficient (Ca2+ )-overload-enhanced...
Silicon/organic heterojunction solar cells (HSCs) based on conjugated polymers, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and n-type silicon (n-Si) have attracted wide attention due to their potential advantages of high efficiency low cost. However, the state-of-the-art efficiencies are still far from satisfactory inferior junction quality. Here, facile treatments were applied by pretreating n-Si wafer in tetramethylammonium hydroxide (TMAH) solution using a...
Molecularly imprinted polymer (MIP) coated Fe3O4 nanoparticles (Fe3O4@MIP) were synthesized by atom transfer radical polymerization (ATRP) and used as highly selective magnetic solid-phase extraction (MSPE) sorbents for trace bisphenol A (BPA) from packed food. The morphological polymeric characteristics of the Fe3O4@MIP characterized transmission electron microscopy Fourier transform infrared spectroscopy. In this work, competitive recognition compounds (4-n-octylphenol diglycidyl ether)...

Abstract A simple and sensitive method was developed validated for the simultaneous determination of 103 pesticide residues in tea by LC‐MS/MS. For analysis with polarity, thermal lability or low volatility, this LC‐MS/MS has an advantage over GC. In work, residual pesticides were extracted from sample ACN then purified using Carb‐NH 2 SPE cartridges. Using multiple reaction monitoring mode, quantified identified most abundant characteristic fragment ions. The recoveries obtained each ranged...
