Enzyme localization can drastically affect signal amplification in signal transduction pathways. [PDF]
PLoS Computational Biology, 2007 Push-pull networks are ubiquitous in signal transduction pathways in both prokaryotic and eukaryotic cells. They allow cells to strongly amplify signals via the mechanism of zero-order ultrasensitivity.

Microcapsule-Based Signal Amplification Method for Biomolecules
Sensors, 2019 The direct signal amplification of target molecules could be an effective means of increasing the sensitivity and reducing the size of biosensors. The purpose of this study was to propose a novel signal amplification method suitable for the detection of ...

Noisy signal amplification in ultrasensitive signal transduction [PDF]
Proceedings of the National Academy of Sciences, 2004 Because intracellular processes are inherently noisy, stochastic reactions process noisy signals in cellular signal transduction. One essential feature of biological signal transduction systems is the amplification of small changes in input signals.

Substantial gain enhancement for optical parametric amplification and oscillation in two-dimensional χ(2) nonlinear photonic crystals [PDF]
, 2008 We have analyzed optical parametric interaction in a 2D NPC. While in general the nonlinear coefficient is small compared to a 1D NPC, we show that at numerous orientations a multitude of reciprocal vectors contribute additively to enhance the gain in ...

Eight-fold signal amplification of a superconducting nanowire single-photon detector using a multiple-avalanche architecture [PDF]
, 2014 Superconducting nanowire avalanche single-photon detectors (SNAPs) with n parallel nanowires are advantageous over single-nanowire detectors because their output signal amplitude scales linearly with n.

Nanoscale field effect transistor for biomolecular signal amplification [PDF]
, 2007 We report amplification of biomolecular recognition signal in lithographically defined silicon nanochannel devices. The devices are configured as field effect transistors (FET) in the reversed source-drain bias region. The measurement of the differential

High intermodulation gain in a micromechanical Duffing resonator
, 2005 In this work we use a micromechanical resonator to experimentally study small signal amplification near the onset of Duffing bistability. The device consists of a PdAu beam serving as a micromechanical resonator excited by an adjacent gate electrode.

Thermodynamically Driven Signal Amplification
, 2023 The field of chemical computation attempts to model computational behavior that arises when molecules, typically nucleic acids, are mixed together. Thermodynamic binding networks (TBNs) is a highly abstracted model that focuses on which molecules are bound to each other in a "thermodynamically stable" sense. Stability is measured based only on how many
