An elusive chemical contribution to SERS is investigated by estimating the chemical coupling strengths through a dynamic relative peak analysis during solvent evaporation from a diluted chemical sample that is drop-deposited on a soft SERS substrate.

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.

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

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.
