Boron-doped diamond powder (BDDP) and boron-doped nanodiamond (BDND) were developed with the aim of expanding area application conductive electrodes. BDDP BDND are powders obtained by depositing a (BDD) layer on surface (DP) (ND) substrates, respectively, using chemical vapor deposition method. As particle size depends that DP substrate, it can be arbitrarily selected in range at least submicro...

PURPOSE Recently robotic approaches to cystectomy have been reported, and while clinical and oncological efficacy continues to be evaluated, potential financial costs have not been clearly evaluated. In this study we present a financial analysis using current cost structures and clinical outcomes for robotic and open cystectomy for bladder cancer. MATERIALS AND METHODS The financial costs of ...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1403. 64 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9651-7. Applications that require electrical energy storage are becoming increasingly diverse. This d...

This paper describes the development of a referenced Electrochemical Paper-based Analytical Device (rEPAD) comprising a sample zone, a reference zone, and a connecting microfluidic channel that includes a central contact zone. We demonstrated that the rEPADs provide a simple system for direct and accurate voltammetric measurements that are referenced by an electrode with a constant, well-define...

Water-activated microbatteries with long shelf life have been demonstrated based on a one-mask micromachining process for the first time. Magnesium is used as the anode and silver chloride or cuprous chloride is used as the cathode in the prototype demonstration. Adding water or aqueous solutions activate the electrochemical reactions between the anode and cathode to release electricity. Experi...

Direct Electron Transfer biosensors, facilitating direct communication between the biomolecule of interest and electrode surface, are preferable compared to enzymatic and mediator based sensors. Although hemoglobin (Hb) contains four redox active iron centres, direct detection is not possible due to inaccessibility of iron centres and formation of dimers, blocking electron transfer. Through the...

Interdigitated microelectrodes (IDEs) functionalized with a cysteamine (Cys) self-assembled monolayer (SAM) were used to fabricate a sensitive, disposable, impedimetric biosensor for prostate specific antigen (PSA) detection. PSA specific monoclonal antibody (anti-PSA) was covalently immobilized on cysteamine modified gold surface of IDEs, using N-ethyl-N’-(3-dimethylaminopropyl) carbodiimide a...

Celiac disease is a gluten-induced autoimmune enteropathy characterized by the presence of tissue tranglutaminase (tTG) autoantibodies. A disposable electrochemical immunosensor (EI) for the detection of IgA and IgG type anti-tTG autoantibodies in real patient's samples is presented. Screen-printed carbon electrodes (SPCE) nanostructurized with carbon nanotubes and gold nanoparticles were used ...

Simple, rapid and accurate detection of ethanol concentration in blood is very crucial in the diagnosis and management of potential acute ethanol intoxication patients. A novel electrochemical detection method was developed for the quantification of ethanol in human plasma with disposable unmodified screen-printed carbon electrode (SPCE) without sample preparation procedure. Ethanol was detecte...

A rapid prototyping of an inexpensive, disposable graphene and copper nanocomposite sensor strip using polymeric flexible substrate for highly sensitive and selective nonenzymatic glucose detection has been developed and tested for direct oxidization of glucose. The CuNPs were electrochemically deposited on to the graphene sheets to improve electron transfer rates and to enhance electrocatalyti...
