Facile Synthesis of Poly (N-isopropylacrylamide) Coated SiO2 Core-shell Microspheres via Surface-initiated Atom Transfer Radical Polymerization for H2O2 Biosensor Applications

In this study, inorganic/organic composites containing poly (N-isopropylacrylamide) coated core-shell SiO2 microspheres were prepared via surface-initiated atom transfer radical polymerization (ATRP). The thermal responsive polymer, N-isopropylacrylamide was treated with methanol, water and CuBr/CuBr2/1,1,4,7,7-pentamethyldiethylenetriamine (PMDETA) at room temperature to form PNIPAM@SiO2 microspheres. The as-prepared PNIPAM@SiO2 microspheres were characterized by FT-IR, TGA, XPS, SEM, TEM analyses. Hemoglobin (Hb) was immobilized onto the surfaces of PNIPAM@SiO2 microspheres via hydrophobic and pi-pi stacking interactions. The as-prepared Hb/PNIPAM@SiO2 electrode exhibits well-defined redox peak at a formal potential of ?0.38 V, validating the direct electrochemistry of Hb. The Hb immobilized composite film retained its bioelectroactivity without any significant loss of catalytic activity. The modified electrode detects H2O2 over a wide linear concentration range (0.1 muM to 333 muM) with a detection limit of 0.07 muM. This modified electrode also successfully detects H2O2 from food and disinfectant samples with appreciable recovery values, validating its practicality. We believe that PNIPAM@SiO2 composite has great potential to be used in the detection of H2O2 and development of other enzyme based biosensors.

Photo-Irresponsive Molecule-Amplified Cell Release on Photoresponsive Nanostructured Surfaces

Cell manipulation has raised extensive concern owing to its underlying applications in numerous biological situations such as cell-matrix interaction, tissue engineering, and cell-based diagnosis. Generally, light is considered as a superior candidate for manipulating cells (e.g., cell release) due to their high spatiotemporal precision and non-invasion. However, it remains a big challenge to release cells with high efficiency due to their potential limitation of the light-triggered wettability transition on photoresponsive surfaces. In this study, we report a photoresponsive spiropyran-coated nanostructured surface that enables highly efficient release of cancer cells, amplified by the introduction of a photo-irresponsive molecule. On one hand, structural recognition stems from topological interaction between nanofractal surfaces and the protrusions of cancer cells. On the other, molecular recognition can be amplified by a photo-irresponsive and hydrophilic molecule by reducing the steric hindrance of photoresponsive components and resisting nonspecific cell adhesion. Therefore, this study may afford a novel avenue for developing advanced smart materials for high-quality biological analysis and clinical diagnosis.

Fabrication of nitrogen-doped hollow carbon nanospheres with variable nitrogen contents using mixed polymer brushes as precursors

Design and synthesis of heteroatoms-doped porous carbon model materials with controllable nitrogen contents and similar pore structure are of great importance for fundamental understanding of the correlation between their intrinsic properties and applications. Herein, we report a synthetic strategy for synthesis of nitrogen-doped hollow carbon nanospheres with variable nitrogen contents, similar pore structure and morphology by pyrolysis of mixed polymer brushes formed through surface-initiated atom transfer radical polymerization of monomer mixtures of styrene and 4-vinylpyridine. With increasing 4-vinylpyridine fractions in the monomer mixture, nitrogen contents in the final carbon products increase up to about 5.5 wt%. As example applications, electrocatalytic performance for oxygen reduction reactions in both basic and acidic media and carbon dioxide adsorption properties of the thus-formed materials are investigated to evaluate the synthetic approach. The results reveal that the higher nitrogen contents doped in carbon do not guarantee the better performance for either electrocatalysis or carbon dioxide adsorption. It is the fraction of pyridinic nitrogen that dominates the electrocatalytic activity and carbon dioxide adsorption capacity. The findings demonstrate that mixed polymer brushes are promising precursors for the formation of heteroatoms-doped carbon materials, particularly as model materials for fundamental understanding their structure?properties correlations.

Boronate decorated membrane via atom transfer radical polymerization for separation and enrichment of polyphenols from tea drinks

Boronate affinity (BA) materials play an important role in the selective separation and enrichment of cis-diol-containing compounds. However, a majority of BA materials suffer from low binding capacity and tedious preparation process. In this work, a novel high-capacity BA membrane was synthesized via a two-step procedure, including immobilization of active bromine groups on a nylon 66 membrane and grafting of poly(4-vinylphenylboronic acid) chains by surface-initiated atom-transfer radical polymerization. The successful synthesis was revealed by scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, and so on. The BA membrane could not only selectively recognize cis-diol-containing compounds by specific interaction between cis-diol and boronic acid ligands, but also extensively adsorb non-cis-diol-containing compounds by hydrophobic (or pi-pi) interaction and B-O coordination effect. The novel BA membrane was used as an extraction material, and some parameters of extraction were optimized in detail. Membrane extraction coupled with ultra-high performance liquid chromatography was applied to the selective enrichment and determination of 10 kinds of polyphenols, including eight cis-diol-containing polyphenols and two non-cis-diol-containing polyphenols. The recoveries at three spiked levels from jasmine green tea were between 91.2% and 100.5% for cis-diol-containing polyphenols, with intraday and interday relative standard deviations ranging from 3.7% to 7.5% and 4.2% to 8.2%, respectively.

Rational design of homo and hetero hexanuclear coordination compounds: Syntheses and magnetic properties of hexacopper and diocopper tetranickel coordination compounds and the crystal structure of a hexacopper coordination compound (see abstract)

New homo- and heterometallic hexanuclear complexes of formula {[Cu(tmen)(H2O)]2[Cu(tmen)]2[Cu2L](H2O)}(ClO4)4 ¡¤ 2 H2O [Cu6- tmen] {[Cu(pmdien)]4[Cu2L]}(ClO4)4 ¡¤ 4 H2O [Cu6-pmdien] and {[Ni(cyclam)]4[Cu2L]}(ClO4)4 ¡¤ 4 H2O [Cu2Ni4-cyclam] [H8L = tetrakis(aminomethylene)methanetetrakis(oxamic acid), tmen = N,N,N’,N’- tetramethylethylenediamine, pmdien = N,N,N’N’,N”- pentamethyldiethylenetriamine, and cyclam = 1,4,8,11- tetraazacyclotetradecane] have been synthesized. The crystal structure of [Cu6-tmen] has been determined by single-crystal X-ray diffraction. The structure consists of cationic {[Cu(tmen)(H2O)]2[Cu(tmen)]2- [Cu2L](H2O)}4+ hexanuclear units. The hexanuclear cation is made up of two symmetry-related oxamato-bridged trinuclear units connected through the central carbon atom C(6) of the L8- ligand. Variable-temperature magnetic susceptibility measurements (1,8-300 K) have been performed for these series of complexes including the dinuclear precursors of formula Na4[Cu2L] ¡¤ 10.5 H2O [Cu2-Na], (NMe4)4[Cu2L] ¡¤ 4 H2O [Cu2-NMe4] and (PPh4)4[Cu2L] ¡¤ 6 H2O [Cu2-PPh4]. The magnetic data have been interpreted. Evidence of a weak intramolecular ferromagnetic interaction between the two Cu(II) ions in [Cu2L]4- has been observed. For the hexanuclear species, the interaction through the oxamato bridge was found to be equal to -6790, -2650, and -1643 yJ (-342, -133, and -82 cm-1) for [Cu6-tmen], [Cu6-pmdien], and [Cu2Ni4-cyclam], respectively. In these complexes, the weak intramolecular ferromagnetic coupling between the two Cu(II) ions within the dinuclear synthon was masked by intermolecular interactions or local anisotropy.

These compounds include [Cu4(pmedien)4(mu4-nptc)(H 2O)4](ClO4)4¡¤2H2O (1), [Cu2(pmedien)2(mu2-2,5-pydc)(H 2O)](ClO4)2¡¤H2O (2), [Cu 3(DPA)3(1,3,5-btc)(ClO4)3] ¡¤H2O (3), [Cu3(DPA)3(HN(CH 2COO)3)(H2O)3](ClO4) 4¡¤3H2O (4), and [Cu3(pmedien) 3(HN(CH2COO)3)(H2O) 3](ClO4)4¡¤2H2O (5) where pmedien = N,N,N?,N?,N?-pentamethyldiethylenetriamine and DPA = di(2-pyridymethyl)amine. X-ray single crystal crystallography reveal the tetra- and di-nulear bridging nature of the fully deprotonated acids H4nptc and 2,5-H2pydc in complexes 1 and 2, respectively. Magnetic susceptibilities of complexes 1 and 2 which were measured at variable temperatures showed very weak antiferromagnetic coupling.

Biaxial Chain Growth of Polyolefin and Polystyrene from 1,6-Hexanediylzinc Species for Triblock Copolymers

Synthesis of polyolefin (PO)-based block copolymers is of immense research interest. In this work, we report a strategy for the construction of polystyrene (PS)-block-PO-block-PS, a useful thermoplastic elastomer, directly from olefin and styrene monomers. Multinuclear zinc species Et[Zn(CH2)6]aZnEt were prepared through successive additions of BH3 and Et2Zn to 1,5-hexadiene. Poly(ethylene-co-propylene) chains were biaxially grown from the a(CH2)6- units in Et[Zn(CH2)6]aZnEt via “coordinative chain transfer polymerization (CCTP)” using the pyridylaminohafnium catalyst. PS chains were subsequently grown in one pot from the generated polymeryl-Zn sites by subsequent introduction of the anionic initiator Me3SiCH2Li¡¤(pmdeta) (pmdeta, pentamethyldiethylenetriamine) and styrene monomers. The fraction of the extracted PS homopolymer grown from the Me3SiCH2 sites was low (homo-PS (g)/total PS (g), 15-22%). The gel permeation chromatography (GPC) curves shifted evidently after styrene polymerization, and change in the molecular weight (I”Mn, 39-56 kDa) was approximately twice the homo-PS Mn (20-23 kDa), in accordance with attachment of the PS chains at both ends of the PO chains. Transmission electron microscopy analysis of the thin films showed segregation of the PS domains in the PO matrix to form spherical or wormlike rippled structures depending on the PS content. The prepared triblock copolymers exhibited elastomeric properties in the cyclic tensile test, similar to the commercial PS-block-poly(ethylene-co-1-butene)-block-PS.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 3030-47-5, you can also check out more blogs about3030-47-5
