Transient bioimpedance monitoring of mechanotransduction in artificial tissue during indentation

includes the microfluidic system and support, can be given as: (20) R s u b = ρ s u b L K k h s K k ′ h s $${{R}_{sub}}=\frac{{{\rho }_{sub}}}{L}\frac{K\left( {{k}_{hs}} \right)}{K\left( {{{{k}'}}_{hs}} \right)}$$ In a similar manner the geometry of the thin film of the conductive medium can be mapped onto the parallel plate geometry [ 36 ]. In this instance: (21) k t f = tanh π g 2 h tanh π s + g 2 h $${{k}_{tf}}=\frac{\tanh \left( \frac{\pi g}{2h} \right)}{\tanh \left( \frac{\pi \left( s+g \right)}{2h} \right)}$$ and: (22

A short tutorial contribution to impedance and AC-electrokinetic characterization and manipulation of cells and media: Are electric methods more versatile than acoustic and laser methods?

multi-sensor chip. The chip has been developed for the monitoring of cell-physiological parameters and cell-proliferation behaviour. Glass-wafer technology ensured the microscopic observability of the on-chip cell culture. A mouse-osteoblast precursor-cell line (MC3T3-E1) was used as a model system (manuscript in preparation). The chip has been combined with a microfluidic channel grid, which was imprinted in poly-dimethyl-siloxane. The glass substrate bore thin-film platinum structures which were covered by 1 μm Si 3 N 4 in most chip areas. Bare platinum structures

Applications of bioimpedance measurement techniques in tissue engineering

example, impedance measurements have been used for continuous monitoring of tissue spheroids ( 62 , 84 , 85 ), as well as estimating the cell size ( 84 , 85 ), proliferation ( 62 ), evaluation of cell concentration ( 86 ) and cell viability ( 87 , 88 ). In addition, this method has been used for monitoring cells behavior by application of bulk ( 89 ) or thin film electrodes ( 90 ), on cells attached to a substrate ( 91 ), on cells in suspension ( 92 ) or on trapped single cell ( 93 ). Microsystems can provide an environment for cell cultures where noninvasive
