Chemical amplification of optoacoustic signals

Nature, 1983
Historically, the optoacoustic effect has been produced in gases through the absorption of IR radiation1–3. As the effect depends only on the conversion of modulated radiation to periodic heating of the gas (which in a closed vessel is equivalent to a sound wave), it is not surprising that the optoacoustic effect can be produced by several different ...

Signal Amplification for Nanobiosensing

2011
One of the major goals in developing novel biological assay methods for the ­detection of biomolecules and DNA hybridization is achieving high sensitivity. The need for ultrasensitive bioassays is of major importance in view of the growing trend toward miniaturized assays.

Amplification of Signaling Events in Bacteria

Science's STKE, 2002
Bacteria respond to extremely shallow chemical gradients by modifying their motility in a process called chemotaxis. This chemotactic response is characterized by high sensitivity to small concentration differences, which extends over a large range of concentrations.

Tyramide Signal Amplification for Immunofluorescent Enhancement

2015
Enzyme-linked signal amplification is a key technique used to enhance the immunohistochemical detection of protein, mRNA, and other molecular species. Tyramide signal amplification (TSA) is based on a catalytic reporter deposit in close vicinity to the epitope of interest.
