Estimation of biochemical network parameter distributions in cell populations [PDF]

open access: yesProceedings of the 15th IFAC Symposium on System Identification (SYSID), Saint-Malo, France, 2009, pp. 1265-1270, 2009
Populations of heterogeneous cells play an important role in many biological systems. In this paper we consider systems where each cell can be modelled by an ordinary differential equation. To account for heterogeneity, parameter values are different among individual cells, subject to a distribution function which is part of the model specification ...

Detection of the melanoma biomarker TROY using silicon nanowire field-effect transistors [PDF]

open access: yesarXiv, 2013
Antibody-functionalized silicon nanowire field-effect transistors have been shown to exhibit excellent analyte detection sensitivity enabling sensing of analyte concentrations at levels not readily accessible by other methods. One example where accurate measurement of small concentrations is necessary is detection of serum biomarkers, such as the ...
