Poly(dimethylsiloxane) (PDMS)-based microfluidic devices are increasing in popularity due to their ease of fabrication and low costs. Despite this, there is a tremendous need for strategies rapidly easily tailor the surface properties these devices. We demonstrate one-step procedure covalently link polymers PDMS microchannels by ultraviolet graft polymerization. Acrylic acid, acrylamide, dimethylacrylamide, 2-hydroxylethyl acrylate, poly(ethylene glycol)monomethoxyl acrylate were grafted...
Abstract Photodynamic therapy (PDT) is a promising method for cancer treatment. Two parameters that influence the efficacy of PDT are light source and oxygen supply. Herein, we prepared system using hemoglobin (Hb)‐linked conjugated polymer nanoparticles (CPNs), which can luminesce supply oxygen. Hb catalyzes activation luminol, poly[2‐methoxy‐5‐(2‐ethylhexyloxy)‐1,4‐phenylenevinylene] (MEH–PPV) absorb chemiluminescence luminol through resonance energy transfer (CRET) then sensitize supplied...
In this work, a novel approach for simple and sensitive determination of alkaline phosphatase (ALP) is developed on the basis an inner filter effect p-nitrophenylphosphate (PNPP) fluorescence gold nanoclusters (AuNCs). AuNCs with high quantum yield 12% were synthesized by one-pot strategy directly applied as fluorescent substance. When mixed PNPP, was remarkably quenched or decreased via since absorption spectrum PNPP overlaps well excitation AuNCs. While in presence ALP, catalytically...
We demonstrate a simple procedure to coat the surfaces of enclosed PDMS microchannels by UV-mediated graft polymerization. In prior applications, only disassembled channels could be coated this method. This limited utility method coatings that easily and tightly seal with themselves. By preadsorbing photoinitiator onto surface microchannels, rate polymer formation at was greatly accelerated compared in solution. Thus, gel did not form lumen microchannels. benzophenone remained on even after...
The phenomenon of sulfur (S) deficiency in Chinese soil is becoming increasingly severe, especially the northeastern saline-sodic wasteland (WL). To determine bioavailability S long-term cultivated paddy with or without organic amendment addition, field experiment site was established and incubation experiments were conducted. Compared to WL, properties have been continuously improved during 15-year (PF) cultivation, ultimately enhancing content carbon (by 242.62 %), total nitrogen 126.49 %)...
Poly(dimethylsiloxane) (PDMS) is an attractive material for microelectrophoretic applications because of its ease fabrication, low cost, and optical transparency. However, use remains limited compared to that glass. A major reason the difficulty tailoring surface properties PDMS. We demonstrate UV grafting co-mixed monomers customize PDMS microfluidic channels in a simple one-step process. By co-mixing neutral monomer with charged different ratios, between those could be selected. Mixtures...

Abstract Aggregate stability and soil organic carbon (SOC) are critical for maintaining structure preserving productivity. Land use substantially affects the process of aggregate stabilization SOC sequestration, yet detailed mechanisms have not been well studied in degraded ecosystems (e.g., saline‐sodic soils). Therefore, to interpret effects land‐use changes on stocks soils, soils were sampled from four major areas (degraded meadow, artificial forest, sorghum field, paddy field) Northeast...
<title>Abstract</title> Soil salinization poses a threat to global food security by deteriorating soil biodiversity and especially various functions. However, how affects the biodiversity-multifunctionality relationship remains largely unknown in agro-ecosystems. Here, we conducted standardized survey of agro-ecosystems across typical gradient at 115 representative agricultural sites, aiming investigate relationships between (encompassing diversity bacteria, fungi, archaea, protists,...
Flexibility is an intrinsic property of proteins and essential for their biological functions. However, because structural flexibility, obtaining high-quality crystals with heterogeneous conformations remain challenging. Here, we show a novel approach to immobilize traditional precipitants onto molecularly imprinted polymers (MIPs) facilitate protein crystallization, especially flexible proteins. By applying this method, the N-terminus human fragile X mental retardation are obtained, whose...
