Aptamer-mediated surface-enhanced Raman spectroscopy intensity amplification.

Nam Hoon Kim et al.

Nano letters, 10(10), 4181-4185 (2010-09-25)

A bifunctional adenosine-sensitive double-stranded DNA aptamer was used to create and control a surface-enhanced Raman spectroscopy (SERS) hot spot between a bulk Au surface and a gold nanoparticle (Au NP) attached to the aptamer via a biotin-avidin linkage. The Au

Free-surface microfluidic control of surface-enhanced Raman spectroscopy for the optimized detection of airborne molecules.

Brian D Piorek et al.

Proceedings of the National Academy of Sciences of the United States of America, 104(48), 18898-18901 (2007-11-21)

We present a microfluidic technique for sensitive, real-time, optimized detection of airborne water-soluble molecules by surface-enhanced Raman spectroscopy (SERS). The method is based on a free-surface fluidic device in which a pressure-driven liquid microchannel flow is constrained by surface tension.

Electrochemical biosensor for detection of BCR/ABL fusion gene using locked nucleic acids on 4-aminobenzenesulfonic acid-modified glassy carbon electrode.

Jinghua Chen et al.

Analytical chemistry, 80(21), 8028-8034 (2008-09-26)

In this study, an electrochemical DNA biosensor was developed for detection of the breakpoint cluster region gene and the cellular abl (BCR/ABL) fusion gene in chronic myelogenous leukemia by using 18-mer locked, nucleic acid-modified, single-stranded DNA as the capture probe.

Sensitive voltammetric determination of tyrosine using multi-walled carbon nanotubes/4-aminobenzeresulfonic acid film-coated glassy carbon electrode.

Ke-Jing Huang et al.

Colloids and surfaces. B, Biointerfaces, 61(2), 176-181 (2007-09-18)

A chemically modified electrode is constructed based on the multi-walled carbon nanotubes (MWNTs)/4-aminobenzeresulfonic acid (4-ABSA) film-coated glassy carbon electrode. The electrocatalytic oxidation of tyrosine (Tyr) is investigated on the surface of the MWNTs/4-ABSA-modified electrode using cyclic voltammetry (CV) and differential

Application of a novel bacterial consortium for mineralization of sulphonated aromatic amines.

Prashant Barsing et al.

Bioresource technology, 102(2), 765-771 (2010-09-25)

A novel bacterial consortium (TJ-2) for mineralization of aromatic amines resulting from decolorization of azo dyes was developed. Three bacterial strains were identified as Pseudomonas pseudoalcaligenes (TJ-21,EU072476), Pseudomonas citronellolis (TJ-22,EU072477) and Pseudomonas testosterone (TJ-23,EU072477) by 16S rRNA gene sequence analysis.
