Pathogenic bacteria pose a devastating threat to public health. However, because of the growing bacterial antibiotic resistance, there is an urgent need develop alternative antibacterial strategies established antibiotics. Herein, iron-doped carbon dots (Fe-CDs, ∼3 nm) nanozymes with excellent photothermal conversion and photoenhanced enzyme-like properties are developed through facile one-pot pyrolysis approach for synergistic efficient therapy wound healing. In particular, Fe doping endows...
Abstract Sonodynamic therapy (SDT) has attracted widespread attention due to its non‐invasiveness and deep tissue penetration. However, the development of efficient sonodynamic nanoplatforms improve therapeutic efficiency is still one main challenges current research. In this work, a new type sonosensitizer prepared by simple method, manganese carbonate nanoparticles (MnCO 3 NPs), used for enhanced SDT. MnCO NPs could generate large amounts 1 O 2 •OH under ultrasound irradiation. At same...
Abstract The high reactive oxygen species (ROS) generation ability and simple construction of sonosensitizer systems remain challenging in sonodynamic therapy against the hypoxic tumor. In this work, we rationally prepared MOF‐derived double‐layer hollow manganese silicate nanoparticle (DHMS) with highly effective ROS yield under ultrasound irradiation for multimodal imaging‐guided (SDT). presence Mn DHMS increased efficiency because it could be oxidized by holes to improve electron–hole...
Abstract Clinical therapy of multidrug resistant (MDR) bacteria‐induced deep‐tissue infections such as pneumonia is highly challenging. Ultrasound (US)‐induced sonodynamic (SDT) a promising strategy for treatment diseases given the strong tissue penetration US. Here, ZIF‐8‐derived carbon@TiO 2 nanoparticles (ZTNs) are developed inhalable sonosensitizers bacterial pneumonia. ZTNs upon US irradiation exhibit an excellent efficacy to produce reactive oxygen species (ROS) and thereby kill...
Ultrasound (US) generates toxic reactive oxygen species (ROS) by acting on sonosensitizers for cancer treatment, and the mechanical damage induced cavitation effects under US is equally significant. Therefore, designing a novel sonosensitizer that simultaneously possesses efficient ROS generation enhanced promising. In this study, carbon-doped zinc oxide nanoparticles (C-ZnO) are constructed mechano-sonodynamic therapy. The presence of carbon (C) doping optimizes electronic structure,...
A kind of manipulative oil in water Pickering emulsion stabilized by heterogeneously modified cellulose nanocrystals (CNCs) and its application as a template for the creation functional polystyrene microspheres were presented this study. First, 18-carbon alkyl long chains selectively introduced at reducing ends CNCs through two-step chemical process including hydrazone reaction amidation reaction. The as-obtained (CNC–C18) then used emulsifiers formation emulsions. Compared with pristine...
Sonodynamic therapy (SDT) has been widely reported as a noninvasive and high-penetration for cancer; however, the design of an efficient sonosensitizer remains urgent need. To address this issue, molybdenum disulfide nanoflowers (MoS2 NF) piezo-sonosensitizers introduced sulfur vacancies on MoS2 NF (Sv-MoS2 to improve their piezoelectric property cancer are designed. Under ultrasonic mechanical stress, Sv-MoS2 resulted in polarization band tilting, which enhanced charge carrier separation...
Structural and chemical deterioration its impact on cell wall mechanics were investigated for visually intact walls (VICWs) in waterlogged archaeological wood (WAW). Cell mechanical properties examined by nanoindentation without prior embedding. WAW showed more than 25% decrease of both hardness elastic modulus.

We report that the graphene sheets can be stably dispersed in water by hydrophobic interaction with polyacrylamide. Most interestingly, resultant graphene–polyacrylamide complexes show a reversible pH responsive property although polyacrylamide itself does not possess such characteristics. This method opens up novel opportunities for potential applications of intelligent sensors, biology, medicine, nanoelectronics and other relevant areas.
In this work, a combination of two fabrication methods, i.e.electrospinning and the hydrothermal reaction, are used to fabricate ZnO/SiO2 hierarchical structure. The structure is made up silica fibers as backbone for supporting epitaxial growth ZnO nanorods. resembles "tube brush" like morphology with high porosity surface area, both which vital factors in water purification. This method offers way construct flexible membrane functional composites To aid electron–hole separation, Ag modified...
ABSTRACT The relationship between the cell wall ultrastructure of waterlogged wooden archeological artifacts and state water bound to walls free in voids is fundamental develop consolidating drying technologies. Herein, a lacquer-wooden ware boat-coffin dating 4th century BC were selected as representative study. Wood anatomy results indicated that they belonged Idesia sp. Machilus sp., respectively. They exhibited typical spongy texture, revealed by SEM observations, their contents had...
Abstract DNA barcoding technology has emerged as one of the most promising tools available to identify timber at species level, contributing monitoring trade and conservation forestry sources. This paper reviews progress, challenges, existing problems in development for wood identification last ten years. There is a focus on optimization extraction methods processed or ancient wood, strategy screening high-resolution barcodes suitable identification, reference database especially priority...
