Single-substrate Enzyme Kinetics: The Quasi-steady-state Approximation and Beyond [PDF]

open access: yesJ. Math. Chem. 51 (2013) 1467, 2012
We analyze the standard model of enzyme-catalyzed reactions at various substrate-enzyme ratios to identify the regions of validity of the quasi-steady-state approximation. Certain prevalent conditions are checked and compared against the actual findings. Efficacies of a few other measures are highlighted. Some very recent observations are rationalized,

Effective inter-symbol interference mitigation with a limited amount of enzymes in molecular communications [PDF]

open access: yesarXiv, 2016
In molecular communication via diffusion (MCvD), the inter-symbol interference (ISI) is a well known severe problem that deteriorates both data rates and link reliability. ISI mainly occurs due to the slow and highly random propagation of the messenger molecules, which causes the emitted molecules from the previous symbols to interfere with molecules ...
