Cotton gauze is a widely used topical hemostatic material for bleeding control, but its high blood absorption capacity tends to cause extra loss. Therefore, development of rapid cotton with less loss great significance. Here, we develop an efficient whose surface slightly modified catechol compound which features flexible long hydrophobic alkyl chain terminated group. Its performance in animal injuries superior standard and Combat GauzeTM. biosafety similar rebleeding hardly occurs when the...
Photocatalytic regeneration of a nicotinamide cofactor, adenine dinucleotide phosphate (NADPH), has emerged as an ideal cascade partner for combination with enzymatic transformations, but it still suffers from low efficiency due to the recombination photogenerated charge carriers. Herein, hierarchical Rh-covalent organic framework (COF)@COF core–shell hollow sphere (CSHS) S-scheme heterojunction is proposed enhance carrier transfer and utilization in photocatalysis regenerate expensive...
Cascade catalysis that combines chemical and biocatalysis has received extensive attention in recent years, especially the integration of metal nanoparticles (MNPs) with enzymes. However, compatibility between MNPs enzymes, stability integrated nanocatalyst should be improved to promote application. Therefore, this study, we proposed a strategy space-separately co-immobilize enzymes pores surface highly stable covalent organic framework (COF), respectively. Typically, Pd NPs were prepared by...
Green synthesis of gold nanoparticles using plant extracts is one the more promising approaches for obtaining environmentally friendly nanomaterials biological applications and environmental remediation. In this study, proanthocyanidins-functionalized were synthesized via a hydrothermal method. The obtained characterized by ultraviolet visible spectrophotometry (UV-Vis), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) X-ray diffraction (XRD)...
Using Chitosan/PEO as the shell and PCL core, chitosan–polyethylene oxide/polycaprolactone nanofibrous mats were prepared successfully by coaxial electrospinning for co-load sequential co-delivery of two drugs.
A simple and efficient strategy was developed to synthesize polyacrylonitrile-copper oxide (PAN-CuO) nanoflowers by growing copper nanoneedles on the surface of polyacrylonitrile (PAN) under mild conditions. Fortunately, obtained PAN-CuO exhibit excellent peroxidase-mimicking activity catalyze oxidation 3,3′,5,5′-tetramethylbenzidine (TMB) form a blue-colored solution with H2O2. The peroxidase-like mechanism originated from generation •OH radical. PAN-CuO-based colorimetric assay used detect...
Hierarchical flower-like NiMnO3 composites were facilely prepared by template-free hydrothermal treatment and calcined under mild conditions. Due to the strong ability absorb oxygen, as-prepared endowed with oxidase-like activity catalyze oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) a blue product without H2O2. Investigations on mechanism indicate that originates from superoxide radical generation. The was selectively inhibited hydroquinone (HQ), which could reduce oxTMB colorless TMB...
Abstract Metal‐enzyme integrated catalysts (MEICs) that combine metal and enzyme offer great potential for sustainable chemoenzymatic cascade catalysis. However, rational design construction of optimal microenvironments accessible active sites in individual nanostructures are necessary but still challenging. Herein, Pd nanoparticles (NPs) Candida antarctica lipase B (CALB) co‐immobilized into the pores surfaces covalent organic frameworks (COFs) with tunable functional groups, affording...
Novel antibacterial nanomaterials have been developed for biomedical applications. The present study involves the preparation and properties of nanofibers from chitosan/polyethylene oxide electrospun incorporated with silver nanoparticles. Silver nanoparticles were efficiently synthesized in situ after ultra violet (UV) AgNO3 as precursor reducing agent protecting agent, respectively. Then resultant solutions into nanofibers. formation was confirmed ultraviolet visible (UV-vis) transmission...

High blood glucose levels, excessive production of reactive oxygen species (ROS), unbalanced inflammatory responses and impaired angiogenesis render chronic wounds more likely to be colonized by bacteria which can form biofilms, leading recurrent infections prolonging disunion. The pH-responsive fibers poly (vinyl alcohol) (PVA)/poly (acrylic acid) (PAA) -epigallocatechin gallate (EGCG) have been constructed. were able swell (pH > 7.4) /shrink < 6.5) reversibly with changes in wound pH,...
