Abstract Recently, there has been a growing demand for ultra‐thin carbonized wood films (CWF) with high shielding efficiency (SE) to replace non‐renewable alternatives. Researchers aim enhance electromagnetic (EM) wave absorption and improve interference (EMI) SE in CWF materials reduce secondary pollution from reflected EM waves. In this work, the composite film (CWF/EP/Co) thickness of 120 µm through process hot‐pressing carbonizing soaked mixed solution water‐borne epoxy (EP) Co/Zn‐MOF (ZIF‐67/8) is obtained. The CWF/EP/Co exhibits excellent conductivity (105 S cm −1 ) demonstrates an EMI (73 dB) at 200 thickness. Remarkably, specific effectiveness (SSE/t) reached 15833.3 dB·cm 2 ·g X‐band, making it highest reported value among all wood‐derived materials. have coefficient (A) 0.4, indicating their absorbing Furthermore, effect large‐scale wallpaper (170 mm×170 mm) confirmed by finite element analysis. Additionally, good mechanical properties effective Joule heating performance. This shows promise applications such as buildings smart homes, providing warming effects.

Liposomal Enzyme Nanoreactors Based on Nanoconfinement for Efficient Antitumor Therapy

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(44)

Enzymatic reactions can consume endogenous nutrients of tumors and produce cytotoxic species are therefore promising tools for treating malignant tumors. Inspired by nature where enzymes compartmentalized in membranes to achieve high reaction efficiency separate biological processes with the environment, we develop liposomal nanoreactors that perform enzymatic cascade aqueous nanoconfinement liposomes. The effectively inhibited tumor growth vivo consuming (glucose oxygen) producing highly hydroxyl radicals (⋅OH). Co-compartmentalization glucose oxidase (GOx) horseradish peroxidase (HRP) liposomes could increase local concentration intermediate product hydrogen peroxide (H2 O2 ) as well acidity due generation gluconic acid GOx. Both H2 accelerate second-step HRP, hence improving overall reaction. biomimetic compartmentalization tandem biocompatible provides a direction developing catalytic nanomedicines antitumor therapy.

Hyaluronic acid-graphene oxide quantum dots nanoconjugate as dual purpose drug delivery and therapeutic agent in meta-inflammation

Journal of Nanobiotechnology, Год журнала: 2023, Номер 21(1)

Abstract Type 2 diabetes mellitus (T2DM) predominantly considered a metabolic disease is now being an inflammatory as well due to the involvement of meta-inflammation. Obesity-induced adipose tissue inflammation (ATI) one earliest phenomena in case meta-inflammation, leading advent insulin resistance (IR) and T2DM. The key events ATI are orchestrated by macrophages, which aggravate state upon activation, ultimately systemic chronic low-grade Non-Alcoholic Steatohepatitis (NASH) through proinflammatory cytokines. CD44 receptor on macrophages overexpressed ATI, NASH, IR. Therefore, we developed targeted Hyaluronic Acid functionalized Graphene Oxide Quantum Dots (GOQD-HA) nanocomposite for tissue-specific delivery metformin. Metformin-loaded GOQD-HA (GOQD-HA-Met) successfully downregulated expression cytokines restored antioxidant status at lower doses than free metformin both palmitic acid-induced RAW264.7 cells diet induced obese mice. Our study revealed that nanocarrier enhanced efficacy Metformin primarily acting therapeutic agent apart from drug platform. properties stem HA GOQD having anti-inflammatory respectively. This unravels function option meta-inflammation where itself acts agent. Graphical

Zeolite-Like Ln-MOF Luminescent Nanosensor for Highly Efficient Detection of l-Noradrenaline

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(2), С. 1940 - 1949

Опубликована: Янв. 13, 2024

l-Noradrenaline (l-NE) is a neurotransmitter released by postganglionic neurons in the sympathetic nerve branch and stimulates secretion of l-NE human blood. Accurate monitoring concentration serum crucial for detecting stimulants preventing fraud competitive events. In this study, we introduce an approach detection using zeolite-like lanthanide metal–organic framework (Ln-MOF) named Eu0.479Tb0.521-ZMOF, constructed with H2bpdc ligand (where stands 2,2′-bipyridine-6,6′-dicarboxylate acid), forming nanorod. Notably, ratiometric luminescent probe Eu0.479Tb0.521-ZMOF showcases superior sensing performance compared to single emission based on Ln-MOF, enabling highly efficient among various antidepressant hormones. The limit (LOD) was 129 μM. Additionally, has been synthesized into nanorods, which promote effective solutions, exhibiting impressive recovery rate ranging from 97.5 100%. membrane, derived successfully developed utilized visual l-NE. conclusion, our study comprehensively elucidates detailed mechanism zeolite-Like Ln-MOFs Eu0.479Tb0.521-ZMOF.
