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

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.
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.
