Genetic tools that permit functional or connectomic analysis of neuronal circuits are rapidly transforming neuroscience. The key to deployment of such tools is selective transfection of target neurons, but to date this has largely been achieved using transgenic animals or viral vectors that transduce subpopulations of cells chosen according to anatomical rather than functional criteria. Here, w...

A nanocomposite capable of simultaneously controlling multiple water pollutants (soluble organic dye and insoluble chemical solvent) has been obtained. The Au and Fe3O4 nanoparticles (NPs) were modified on a graphene oxide (GO) surface via light reduction and covalent attachment. The obtained Fe3O4-Au-GO nanocomposite has magnetic driving ability and catalytic applications. The nanocomposite ca...

Dye sensitizers can significantly affect power conversion efficiency of dye-sensitized solar cells (DSSCs). Porphyrin-based dyes are promising sensitizers due to their performances in DSSCs. Here, based upon a N-fused carbazole-zinc porphyrin-free-base porphyrin triad containing an ethynyl-linkage (coded as DTBC), the novel porphyrin dyes named DTBC-MP and DTBC-TP were designed by varying the p...

In this work, pillared bentonite with Al−Fe (Al−Fe−PILC) was synthesized and used as a heterogeneous Fenton-like catalyst in the oxidation of tartrazine azo-dye an aqueous solution. The modification Al-Fe mixed system concentrated medium, ultrasound assisted intercalation carried out, obtained characterized by XRF, XRD, N2 adsorption at 77 K. Al−Fe−PILC, using different amounts H2O2, expressed ...

Differential protein expression analysis based on modification of selected amino acids with labelling reagents has become the major method of choice for quantitative proteomics. One such methodology, two-dimensional difference gel electrophoresis (2-D DIGE), uses a matched set of fluorescent N-hydroxysuccinimidyl (NHS) ester cyanine dyes to label lysine residues in different samples which can b...

We develop a new strategy of using surface functionalized small molecule organic dye nanoparticles (NPs) for targeted cell imaging. Organic dye (2-tert-butyl-9,10-di(naphthalen-2-yl)anthracene, TBADN) was fabricated into NPs and this was followed by surface modification with an amphipathic surfactant poly(maleic anhydride-alt-1-octadecene)-polyethylene glycol (C18PMH-PEG) through hydrophobic in...

The development of effective sorbents based on cheap natural raw materials for water purification from synthetic organic dyes is an important environmental problem. It known that layered silicates are distinguished by mechanical strength, thermal and chemical resistance, high dispersion, ion exchange, availability low cost. However, the main disadvantage clays their insufficiently sorption capa...

ABSTRACT. The utilization of a metal organic framework (ZIF-8) modified by Fe3O4 nanoparticles was used to accomplish adsorption Rhodamine B (RB) from aqueous solutions. SEM, XRD, IR, and BET analyses were all characterize the composite (Fe3O4@ZIF-8). surface area this adsorbent 478.4 m2/g. X-Ray diffraction spectroscopy detect modification utilizing electron microscopy (SEM) scanning with 48 n...

A new method for cardiovascular shunt detection is described using the indicator-dilution principle applied to blood conductivity changes produced by 5 per cent saline. It possesses these distinct advantages over the Evans blue technic: (1) an unlimited number of deter-minations can be made without an increasing blood dye background or bluish discoloration of the patient, (2) oximetric determin...
