A highly sensitive and water-soluble "switch-on" fluorescent probe with aggregation-induced emission characteristics was developed for protein quantification and visualization. It offers a rapid, economic and effective way for the assay of complete serum proteins and disease-marker proteins.
In this paper, global-like dendrimers, G1-TPA, G2-TPA and G3-TPA, bearing 9, 21 and 45 azobenzene chromophore moieties, respectively, were conveniently prepared with high purity and satisfactory yields, through the combination of divergent and convergent approaches, coupled with the utilization of the powerful Sharple…
Super tough carbon nanotube (CNT) reinforced nanocomposites require both the unique interaction and effective stress transfer between CNTs and polymer chains. When CNT reinforced nanocomposites are stretched, the crack interfaces are usually bridged by CNTs, and energy can be absorbed during deformation before fractur…
We report synthetic routes to both cubic and hexagonal phase Cu2−x(SySe1−y) alloy nanocrystals exhibiting a well-defined near-infrared valence band plasmon resonance, the spectral position of which is dependent mainly on x, i.e. on Cu stoichiometry, and to a lesser extent on the crystal phase of the NCs. For cubic Cu2…
Metallosupramolecular π-amphiphiles are emerging as a new class of adaptive materials that combine the ability of π-conjugated systems to self-assemble in a “programmed” fashion and the versatile coordination geometry and well-known optical, electronic and magnetic properties of metal ions. In particular, their aqueou…
Four organic-decorated quaternary TM-Hg-Sb-Q compounds, namely, [Mn(phen)](2)HgSb(2)S(6) (phen = 1,10-phenanthroline) (1) and isomorphic [TM(tren)]HgSb(2)Se(5) (TM = Mn (2), Fe (3), Co (4); tren = tris(2-aminoethyl)amine) have been solvothermally prepared, and structurally characterized by single crystal X-ray diffrac…
The inferior olive (IO) forms one of the major gateways for information that travels to the cerebellar cortex. Olivary neurons process sensory and motor signals that are subsequently relayed to Purkinje cells. The intrinsic subthreshold membrane potential oscillations of the olivary neurons are thought to be important…
MnO2 nanoparticles uniformly distributed and tightly anchored on graphene are prepared using an ethanol-assisted graphene-sacrifice reduction method, producing composite electrodes with tunable energy density (up to 12.6 Wh kg−1) and power density (up to 171 kW kg−1) via rational design of the oxide/graphene ratio.
Deposition of nanostructures such as carbon nanotubes on Si wafers to make heterojunction structures is a promising route toward high efficiency solar cells with reduced cost. Here, we show a significant enhancement in the cell characteristics and power conversion efficiency by growing a silicon oxide layer at the int…
The reduction-sensitive shedding of hydrophilic shells has recently emerged as a simple, effective and general approach to achieve markedly improved intracellular drug release from micelles. Here, the effects of disulfide content on reduction-sensitivity, triggered drug release and the anti-tumor activity of shell-she…
In the present work, we demonstrate the feasibility to form an aligned Nb(2)O(5) nanotube layer by self-organizing anodization of Nb in a NH(4)F-glycerol electrolyte. In order to achieve a nanotubular rather than a nanoporous layer, careful optimization of the anodization electrolyte is required. We show that only in…
Self-assembled structures adsorbed on carbon nanotubes and other nanofibres offer a plethora of opportunities to endow them with new functions and to integrate them into devices and materials. At the same time they are key to solve the greatest problem in carbon nanotube utilisation--debundling and individualisation.…
Synthetic silica nanospheres of 20 and 100 nm diameter were produced via the sol‐gel method to be used as filler in polypropylene (PP) composites. Modification of the silica surface was further performed by reaction with organic chlorosilanes in order to improve the particles interaction with the hydrophobic polyolefi…
The self-assembly of small molecules provides a potentially powerful method to create functional nanomaterials for many applications ranging from optoelectronics to oncology. However, the design of well-defined nanostructures via molecular assembly is a highly empirical process, which severely hampers efforts to creat…
Organic additives are well known to influence the nucleation and growth of minerals. A combination of experimental and theoretical methods has been used to probe how three simple additives, containing varying numbers of carboxylate groups, influence the early stages of the growth of calcium carbonate. Computationally,…
A modular system for detecting protease activity via enzyme-triggered gel formation is described. Protease-specific recognition sequences are utilized to achieve enzyme specificity. Artificial blood clotting is demonstrated by activating endogenous thrombin to trigger gelation in fibrinogen-deficient blood plasma.
Zinc ferrite nano-particles are synthesised by advanced combustion route. The nano-sized Zn ferrite characterized by X-ray diffraction (XRD), Scanning electron micrographs (SEM) and Energy dispersive X-ray (EDX) techniques. The magnetic properties were determined by using vibrating sample magnetometer (VSM). The prepa…
We report on a joint experimental–theoretical study of collective diffusion in, and static shear viscosity of solutions of bovine serum albumin (BSA) proteins, focusing on the dependence on protein and salt concentration. Data obtained from dynamic light scattering and rheometric measurements are compared to theoretic…
The stoichiometric reaction of the salicylaldimine derivatives (L1-L12) with trimethylaluminium afforded the corresponding dimethylaluminium aldiminophenolates (C1-C12), which were fully characterized by NMR spectroscopy and elemental analysis. The molecular structures of the representative complexes C1, C6, and C8 we…
We have successfully developed a facile two-step anodization combined layer-by-layer (LBL) self-assembly route for rapid fabrication of well-defined metal-TiO(2) nanoring/nanotube combined nanostructures, i.e. M/T-NRNT (M = Au, Ag, Pt). These hierarchically self-assembled hybrid systems are demonstrated to exhibit ver…
