There is an ongoing restructuring process in the healthcare services all over the world, occurring with more intensiveness in the developed countries. The world of healthcare delivery includes the concept of “continuity of care”. This leads us to think about a shift of the concept hospital-centered healthcare to a new patient/citizen centered healthcare as well as from cure to prevention. Strong and reliable textile electrodes could be the first step towards the necessary health data for patient/citizen-centered healthcare and consequently prevention. Textile electrodes have the potential for continuous measurement, of physiological and physical parameters from patients to service providers, family and other support people. In order to design a reliable wearable device to detect, and consequently help in the cure of diseases, textile electrodes can provide a useful contribution. However it is necessary to test the new textile electrodes intensively in order to obtain reliable answers of the physiological signals. For that, it is necessary to know or create conditions of temperature and force, and to control the humidity for each measurement.

Some Investigations on Aperture Size in RF Ion Traps

4839 руб.
This monograph presents results of investigations on fields and multipole expansion coefficients in axially symmetric (referred to as 3D) and two dimensional (2D) ion trap mass analysers. 3D mass analysers have a three-electrode geometry with two (electrically shorted) endcap electrodes and one central ring electrode. rf-only or rf/dc potential applied across the electrodes creates a linear trapping field in the central cavity of the mass analyser. 2D mass analysers have four longitudinal electrodes in which the opposite pairs of electrodes are electrically shorted. Here, rf-only or rf/dc potential applied across the pair of electrodes creates a linear trapping field and fragment ions of the analyte gas are trapped along the central axis of the mass analyser. Both these mass analysers have apertures machined on the electrodes (holes in case of 3D traps and slits in case of 2D traps) to permit entry of electrons for ionising the analyte gas and for collection of destabilized fragment ions. This thesis is concerned with how these apertures influence the fields and multipole expansion coefficients within the traps. This thesis is divided into five chapters.

Modified electrodes are a very active area of electrochemistry, with multiple and widespread uses. They are a central component in many electrochemical devices, in which usually a thin membrane covers the electrode, as in Proton Exchange Fuel cells. Thus, understanding the structure and molecular processes at electrode/membrane interfaces constitutes an important issue for an efficient development of these devices. In this work, Nafion® coated Pt(111) electrodes were studied and experimental results were explained in light of two different theoretical approaches. Initially, the structure and dynamics of the electrode/SPE interface was described in terms of the acid/base equilibrium and the different mobility of membrane ionic groups. The model extends the conceptual framework for the interpretation of CVs for these systems and the general theory for electrified interfaces. Additionally, it provides a tool towards the understanding of the electrocatalytic activity on modified electrodes.

Protein is the essential part of human body, in hemodialysis process sometimes it seeps out through dialysis membrane, which enters in waste dialysate material. This book focuses on a protein sensor which can be placed in dialysis machine to monitor the protein leakage in dialysate material. The sensor consists of electrodes system and micropump. The micropump carries the dialysate material towards the electrodes and electrodes sense the presence of protein in dialysate material. The protein sensor is composed of three sensing electrodes, including a working electrode, a counter electrode and a reference electrode. The principle of the proposed sensor is the change in the electric current between the working and the reference electrodes. When protein is absorbed on to the working electrode it reduces the conducting area, as a result resistance increases and current decreases between working electrode and reference electrode. This change of current is used for the measurement of the concentration of protein in the waste dialysate material. The purposed sensor can also be use for urinary protein.

Advancements in the micro/nano-fabrication techniques have opened up new avenues for the development of portable and easier-to-use biosensors. Over the last few years, carbon electrodes have been widely used as sensing units in biosensors due to their attractive physiochemical properties. This book details different strategies to develop functionalized high surface carbon micro/nano-electrodes for electrochemical and biosensing devices. Carbon electrodes were fabricated via carbon-MEMS technique, which is based on pyrolyzing prepatterned photoresist. To increase the surface area of the carbon electrodes, multiple approaches such as (i) fabrication of porous 3D carbon microarrays, (ii) conformal coating of graphene onto 3D carbon microarrays, and (iii) fabrication of controllable carbon nanostructures were investigated. For carbon surface functionalization to covalently attach biomolecules, different oxidation techniques and the resultant surface carbon–oxygen groups were analyzed and compared. Lastly, label-free detection of platelet-derived growth factor oncoprotein, a cancer biomarker, was demonstrated on 3D carbon microarrays platform with sub-nanomolar detection limit.

Ion selective electrodes (ISEs) are electrochemical sensors that allow potentiometric determination of the activity of certain ions in the presence of other ions in the sample solution. Potentiometric sensors are essentially passive electrochemical devices, in which changes in the electromotive force (emf) are monitored under virtually zero current conditions. In so-called direct potentiometry, the emf is ideally a function of the activity of only one chosen sample-ion so that it can be selectively assessed in the presence of other ions. Achieving sufficient selectivity to measure one ion in the presence of others has long been the main focus of research in this field. This work has been carried out to present and characterize new plastic membrane, coated wire and chemically modified carbon paste electrodes for the determination of the antihistaminic drug, Ketotifen fumarate. The electrodes are based on individual and/or mixed ion-associates formed from the ion-associations of the drug cation with anions of phosphotungstate and tetraphenylborate. The electrodes were constructed and fully characterized.Each electrode was applied to the potentiometric determination of the drug cation
