Detecting colorectal cancer using electrical impedance spectroscopy: anex vivofeasibility study

Staging of colorectal cancer using serum metabolomics with 1HNMR Spectroscopy

Objective(s): Determination of stages of colon cancer is done by biopsy usually after surgery. Metabolomics is the study of all the metabolites using LC-MS and 1HNMR spectroscopy with chemometric techniques. The stages of colon cancer were detected from patients' sera using 1HNMR. Materials and Methods: Five ml blood was collected from 16 confirmed patients referred for colonoscopy.  One group ...

Review Article: Application of Electrical Impedance Spectroscopy in Bladder Cancer Screening

Introduction Bladder cancer is the most common malignancy in elderly people and most bladder cancers are transitional cell carcinomas (TCC). Bladder pathology is usually investigated visually by cystoscopy and this technique can represent different conditions ranging from simple inflammation to flat CIS. However, biopsies must be taken from the suspected area to obtain diagnostic information. T...

Characterization of Physiological Glucose Concentration Using Electrical Impedance Spectroscopy

Non-invasive glucose monitoring is crucial for effective diabetes mellitus treatment while a sound correlation of a non-invasive parameter to glucose level variation is quite challenging. This paper presents characterization of glucose concentrations using Electrical Impedance Spectroscopy (EIS) in three different solutions: 1) 0.9% NaCl, 2) Saline (NaCl 1.3gm, KCl 0.75gm, Na3C6H5O7 1.45gm, D-g...

Classification of Breast Tissue Using Electrical Impedance Spectroscopy

Electrical Characteristics of Biomodified Electrodes using Nonfaradaic Electrochemical Impedance Spectroscopy

We demonstrate a nonfaradaic electrochemical impedance spectroscopy measurement of biochemically modified gold plated electrodes using a two-electrode system. The absence of any redox indicator in the impedance measurements provide more precise and accurate characterization of the measured bioanalyte at molecular resolution. An equivalent electrical circuit of the electrodeelectrolyte interface...
