We demonstrated the surface functionalization of a highly three-dimensional, superhydrophilic wicking substrate using light to immobilize functional biomolecules for sensor or microarray applications. We showed here that the three-dimensional substrate was compatible with photo-attachment and the performance of functionalization was greatly improved due to both increased surface capacity and re...

a novel, simple, sensitive and effective method has been developed for preconcentration of lead. this solid-phase extraction adsorbent was synthesized by functionalization of graphenes with covalently linked n -methyl-glycine and 3, 4-dihydroxybenzaldehyde onto the surfaces of graphite. the method is based on selective chelation of pb (ii) on surfactant coated c 18 , modified with functionaliza...

The [O] [H] functionalization of carbon nanotube (CNT) was studied using oxygen–hydrogen (O2–H2) gas mixture direct current (DC) glow discharge plasma technique for cathode/CNT-anode separation of 0.10 ± 0.01 cm. O2 and H2 were fixed at flowrate of 10.0 ml/min in order to obtain gas mixture ratio of 1:1. During the (O2–H2) gas mixture DC glow discharge, current–voltage (I–V) characteristic of g...

Getting rid of the tubes: An assessment of the retention of functionalized multi-walled carbon nanotubes (MWNTs) in the organs of mice was carried out using single photon emission computed tomography and quantitative scintigraphy (see scheme). Increasing the degree of functionalization on MWNTs enhanced renal clearance, while lower functionalization promoted reticuloendethelial system accumulat...

The near-field of surface plasmons is locally confined to nanometer dimensions. Here, we use surface plasmons to initiate polymer-functionalization of mesoporous silica films allowing subsequent ionic permselectivity gating based on polymer charge. We expect this functionalization approach to open a new dimension of functional miniaturization e.g. in nanofluidics.

A novel porous organic polymer has been synthesized using the molecular building block approach to deliberately encompass aldehyde functionalities amenable to post functionalization. The resultant porous framework allows a facile, one-step quantitative and post-synthetic functionalization by amines, permitting enhanced CO2 sorption properties.

Aluminosilicate glasses offer wide-ranging potential as enabling materials for a new generation of optical devices operating in harsh environments. In this work, nonconventional manufacturing process, the molten core method, is employed to fabricate and study sapphire (Al2O3) YAG (yttrium aluminum garnet) derived all-glass silicate fibers which femtosecond (fs) laser used imprint oriented nanos...

Functionalization of single-walled carbon nanotubes sSWNTsd by isotropic plasma treatment was studied using resonant Raman spectroscopy. It was shown that plasma-induced functionalization results in the uniaxial isotropic constriction of the nanotubes but preserves their overall structural integrity. It was demonstrated that NH3 ·H2O and hexamethyldisiloxan plasmas yield various types of conduc...

Recent developments in nanotechnology have provided new tools for both cancer imaging and treatment. The functionalization of the nanocarrier based drugs using biological ligands allows increasing specificity of drug targeting enhancing efficacy and reducing side effects. In this paper some current nanocarrier based drugs are described and the principles for their functionalization in cancer tr...

A catalytic meta-selective C-H functionalization of 2-phenylpyridines using a range of tertiary halides is described. The protocol is simple to perform and uses commercially available reagents to construct challenging quaternary carbon centres in a regioselective manner. Preliminary studies suggest the C-H functionalization proceeds through a radical process directed via a remote σ-activation.
