Building nanoSPR biosensor systems based on gold magnetic composite nanoparticles.

J. Nanosci. Nanotechnol. 13(8) , 5485-92, (2013)

Composite Fe3O4/Au nanoparticles are attracting considerable interest in developing visual and specific detection of biomolecular due to their unique physical and chemical properties. Here, two localize surface plasmon resonance (LSPR) probes based on Fe3O4/A...

A pH-responsive nano-carrier with mesoporous silica nanoparticles cores and poly(acrylic acid) shell-layers: fabrication, characterization and properties for controlled release of salidroside.

Int. J. Pharm. 446(1-2) , 153-9, (2013)

A novel pH-responsive nano-carrier MSNs-PAA, possessing mesoporous silica nanoparticles (MSNs) cores and poly(acrylic acid) (PAA) shell-layers, was developed for controlled release of salidroside. The vinyl double bonds modified MSNs were synthesized by using...

Role of the Mmr efflux pump in drug resistance in Mycobacterium tuberculosis.

Antimicrob. Agents Chemother. 57(2) , 751-7, (2013)

Efflux pumps are membrane proteins capable of actively transporting a broad range of substrates from the cytoplasm to the exterior of the cell. Increased efflux activity in response to drug treatment may be the first step in the development of bacterial drug ...

Application of surfactant assisted dispersive liquid-liquid microextraction as an efficient sample treatment technique for preconcentration and trace detection of zonisamide and carbamazepine in urine and plasma samples.

J. Chromatogr. A. 1308 , 25-31, (2013)

A simple, rapid, and efficient method, based on surfactant assisted dispersive liquid-liquid microextraction (SA-DLLME), followed by high performance liquid chromatography (HPLC) has been developed for simultaneous preconcentration and trace detection of zoni...

Sorption and transport studies of cetyl trimethylammonium bromide (CTAB) and Triton X-100 in clayey soil.

J. Environ. Sci. (China) 25(3) , 576-84, (2013)

Surfactants are soil washing agents and facilitators for subsurface remediation of hydrocarbon spills. It is important to understand the sorption and transport behavior of surfactants for enhanced soil remediation. The adsorption and desorption isotherms of c...

The colorimetric detection of Pb2+ by using sodium thiosulfate and hexadecyl trimethyl ammonium bromide modified gold nanoparticles.

Dalton Trans. 42(15) , 5485-90, (2013)

A simple, rapid colorimetric detection method for Pb(2+) in aqueous solution has been developed by using sodium thiosulfate (Na2S2O3) and hexadecyl trimethyl ammonium bromide (CTAB) modified gold nanoparticles (Au NPs). Na2S2O3 was added into the Au NP soluti...

Ex vivo microbial leakage after using different final irrigation regimens with chlorhexidine.

J. Appl. Oral Sci. 21(1) , 74-9, (2013)

To assess the influence of final irrigation protocols with chlorhexidine in the coronal leakage of Enterococcus faecalis in filled root canals.Seventy single-root canals from extracted teeth were prepared using ProTaper instruments. The irrigation protocol ac...

Charged surfactants induce a non-fibrillar aggregation pathway of amyloid-beta peptide.

J. Pept. Sci. 19(9) , 581-7, (2013)

The amyloid β-peptide with a sequence of 42 amino acids is the major constituent of extracellular amyloid deposits in Alzheimer's disease plaques. The control of the peptide self-assembly is difficult to achieve because the process is fast and is affected by ...

Micelle-induced multiple performance improvement of fluorescent probes for H2S detection.

Anal. Chim. Acta 768 , 136-42, (2013)

In this paper, two colorimetric and turn-on fluorescent probes N-[2-(2-hydroxy)-ethoxy] ethyl-4-azido-1,8-naphthalimide (SS1) and N-butyl-4-azido-1,8-naphthalimide (SS2) for selective recognition of H2S were designed and synthesized. The probes were construct...

Use of surface plasmon resonance to study the adsorption of detergents on poly(dimethylsiloxane) surfaces.

Electrophoresis 34(8) , 1249-52, (2013)

This paper demonstrates the use of surface plasmon resonance to study adsorption (either reversible or irreversible) of detergents on PDMS surfaces in real time. The surface plasmon resonance measurements can directly provide information about the adsorption/...
