Quinaldine and Indole based pH Sensitive Colorimetric Chemosensor and their application of nanofiber

Bae J.S., Kim S-H, Son D.H. Lee Y-A., Kyungpook National University, KR

Colorimetric chemosensors are now considered as one of the most effective analytical method used in the environment monitoring. Colorimetric chemosensors for pH sensing can easily detect the primary danger or change of the surrounding environment [...]

Amplified On-Chip Fluorescent and Colorimetric Detection of DNA and RNA Hybridization by Surface-Initiated Enzymatic Polymerization

Tjong V., Yu H., Hucknall A., Chilkoti A., Duke University, US

We present a new on-chip, isothermal signal amplification technique for direct detection of unmodified DNA and RNA on microarrays using terminal deoxynucleotidyl transferase (TdT), a template-independent DNA polymerase that catalyzes the sequential addition of deoxynucleotides [...]

Carbon Nanotube-based Labels for Sensitive Nucleic Acids Detection

Lee A.C., Ye J.S., Tan S.N., Poenar D., Sheu F.S., Heng C.K., Lim T.M., National University of Singapore, SG

A novel multiple-labelled conjugate with carbon nanotubes (CNTs) to amplify hybridization signal was developed to improve the nucleic acids assay sensitivity. The carboxylated CNTs were functionalized by horseradish peroxidase (HRP) and single-stranded oligonucleotides via diimide-activated [...]
