An efficient analysis of nanomaterial cytotoxicity based on bioimpedance

Nanotechnology, 2010
In the emerging nanotechnology field, there is an urgent need for the development of a significant and sensitive method that can be used to analyse and compare the cytotoxicities of nanomaterials such as carbon nanotubes (CNTs) and gold nanoparticles (AuNPs), since such materials can be applied as contrast agents or drug delivery carriers.

Bioimpedance vector analysis as a measure of muscle function

Clinical Nutrition, 2009
The impedance vector produced by an alternating current in the bioimpedance analysis can be seen as a standardised test of cellular mass and function since reactance is believed to reflect the mass and integrity of cell membranes. This study investigated the association between resistance and reactance normalised for height (R/H and Xc/H), and muscle ...

Design and uncertainty analysis of a bioimpedance measurement channel

2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2013
This work presents the design and uncertainty analysis of a bioimpedance measurement channel for use in electrical impedance tomography (EIT). A bioimpedance measurement channel was designed. Then the random error of each stage of the project as well as the entire channel was measured. The loads used were resistive, in the range of 100 Ω -1K Ω.

A comparison of the whole-body and segmental methodologies of bioimpedance analysis

Acta Diabetologica, 2003
Theory supports the use of a segmental methodology (SM) for bioimpedance analysis (BIA) of body water (BW). However, previous studies have generally failed to show a significant improvement when the SM is used in place of a whole-body methodology. A pilot study was conducted to compare the two methodologies in control and overweight subjects.

Bioimpedance Analysis for the Characterization of Breast Cancer Cells in Suspension

IEEE Transactions on Biomedical Engineering, 2012
The bioimpedance spectroscopy (BIS) technique is potentially a useful tool to differentiate malignancy based on the variation of electrical properties presented by different tissues and cells. The different tissues and cells present variant electrical resistance and reactance when excited at different frequencies.

Reference Values for Multifrequency Bioimpedance Analysis in Dialysis Patients

Blood Purification, 2004
<i>Background:</i> The role of multifrequency bioimpedance (MF-BIA) in the assessment of fluid status in dialysis patients is still not fully elucidated. Especially, the predictive value of reference values for extracellular water (ECW) has not yet been addressed.

Modelling of Bioimpedance Measurements: Application to Sensitivity Analysis

2014
A technology for high-resolution efficient numerical modeling of bioimpedance measurements is considered that includes 3D image segmentation, adaptive unstructured tetrahedral mesh generation, finite-element discretization, and the analysis of simulation data. The first-order convergence of the proposed numerical methods on a series of unmatched meshes

Liver Cancer Analysis Using Bioimpedance

2015
In this work the impedance analysis is used in order to determinate differences between tumor and unaltered liver tissue. The electrical characterization of tissues at 10 to 200 KHz is obtained by the four electrode measurement method. The difference between the tissues is determined by phase angle measured at 50 KHz.
