Signal Amplification: Let's Turn Down The Lights
نویسنده
چکیده
G protein activation by membrane-bound receptors initiates a chain reaction that amplifies cellular responses to external signals. In retinal photoreceptors, amplification by the phototransduction cascade is regulated by quickly switching off the visual pigment that acts as the receptor for light.

Applicability of the Dendrimer-quantum Dot (Den-QD) Bioconjugate as a Novel Nanocomposite for Signal Amplification in the Fabrication of Cocaine Aptasensor
A selective aptasensor was developed using the electrochemical transduction method for the ultrasensitive detection of cocaine. In this method, dendrimer-quantum dot (Den-QD) bioconjugate was utilized as a specific nanocomposite to efficiently fabricate the aptasensor. CdTe QD, which carries highly significant properties, was immobilized on the surface of a glassy carbon electrode (GCE), and po...
متن کاملComparing signal amplification of thiocyanated Gold nanoparticles in the presence of different ions
Detecting is the most important section in all kinds of sensors. In this regard, the amplification of surface plasmon resonance intensity of gold colloids nanoparticles (GNPs) was studied in the presence of several ions. GNPs were synthesized and then capped by thiocyanate and characterized via DLS and TEM image. In the next step the effect of different concentrations of ions such as iron, copp...

متن کاملRapid detection of TEM-type extended-spectrum β-lactamase (ESBL) mutations using lights-on/lights-off probes with single-stranded DNA amplification.
Rapid identification of specific TEM-type β-lactamase genes in bacterial infections is important for determining appropriate clinical treatment. We report here the design and initial testing of a molecular diagnostic assay capable of amplifying a large segment of the blaTEM gene, as well as detecting widely spaced extended-spectrum β-lactamase (ESBL) mutations and inhibitor-resistant TEM (IRT) ...
متن کاملDeveloping an Analytical Model and Simulation of The Contraflow Left-Turn Lane at Signalized Intersections
At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...
