Chemical Sensors towards Environmental Toxic Molecule Monitoring: Fluores-cent Probes for Detection of Thiophenol

Chemical Sensors for Environmental Monitoring and Homeland Security

35 Chemical sensors consist of a recognition element that is sensitive to stimuli produced by various chemical compounds (analyte) and a transduction element that generates a signal whose magnitude is functionally related to the concentration of the analyte. Chemical sensors also include a special branch referred to as biosensors for the recognition of biochemicals and bio-reactions. The use of...

Synthesis of Oligonucleotide Conjugates Carrying Viologen and Fluores- cent Compounds

The preparation of oligonucleotide conjugates carrying viologen and fluorescein is described. Reaction of the appropriate carboxyl derivatives with oligonucleotides carrying aliphatic amino groups gave the desired compounds. A simple method for the introduction of the amino group at the 5’-end of the oligonucleotides is reported.

Micro- and nanomechanical sensors for environmental, chemical, and biological detection.

Micro- and nanoelectromechanical systems, including cantilevers and other small scale structures, have been studied for sensor applications. Accurate sensing of gaseous or aqueous environments, chemical vapors, and biomolecules have been demonstrated using a variety of these devices that undergo static deflections or shifts in resonant frequency upon analyte binding. In particular, biological d...
