Combining Complement Fixation and Luminol Chemiluminescence for Ultrasensitive Detection of Avian Influenza A rH7N9

03-Feb-2016 | Man Li; ZhuanZhuan Shi; Ling Yu; Changming Li, Analyst, 2016

The complement fixation test (CFT) is a serological test that can be used to detect the presence of either specific antibody or antigen to diagnose infections. In a conventional CFT, the assay result is determined by observing the clarity of the reaction solution or sediment of red cells by eyes. ...


Stochastic Detection and Characterisation of Individual Ferrocene Derivative Tagged Graphene Nanoplatelets

02-Feb-2016 | Haoyu Wu; Qianqi Lin; Christopher Batchelor-McAUley; Luís M Gonçalves; Carlos F. R. A. C. Lima; Richard G Compton, Analyst, 2016

Graphene nanoplatelets (GNPs) are ‘tagged’ with 1-(biphen-4-yl)ferrocene. Chronoamperometry is then utilised to observe single particle impacts when GNPs suspended in solution collide with a carbon fibre micro wire electrode held at an oxidising potential, resulting in current/time transient ...


Development and validation of a CE‐MS method for the targeted assessment of amino acids in urine

30-Jan-2016 | Karina T. Rodrigues, Djalila Mekahli, Marina F. M. Tavares, Ann Schepdael, ELECTROPHORESIS, 2016

A CE‐ESI‐MS method was developed and validated for the separation and quantitative analysis of amino acids in urine. Experimental parameters related to the CE‐MS interface, background electrolyte (BGE) and mass spectrometer (MS) settings were optimized providing a good separation of 27 amino ...


A Ruthenium Complex/Carbon Nanotube Based Electrode as the First Electrochemical Sensor for Simultaneous Sensing of D‐Penicillamine, 6‐Thioguanine and Catecholamines

27-Jan-2016 | Mohammad Mazloum‐Ardakani, Mohammad Ali Sheikh‐Mohseni, Masoud Salavati‐Niasari, Electroanalysis, 2016

Abstract The electrochemical behavior of a synthesized Ru complex (RuL) was investigated at multiwalled carbon nanotubes modified carbon paste electrode. Some special properties of the electrochemical response of this modified electrode are suitable charge transfer rate, repeatability and ...


Superhydrophobic ceria on aluminum and its corrosion resistance

27-Jan-2016 | Beibei Wan, Junfei Ou, Damei Lv, Mingshan Xue, Fajun Wang, Huiming Wu, Surface and Interface Analysis, 2016

Superhydrophobic ceria on the aluminum substrate was fabricated, and its corrosion resistance was investigated by different techniques. For example, the so‐obtained superhydrophobic sample was immersed into the NaCl aqueous solution, and the variations in the surface wettability as well as the ...


Electron microscopic visualization of complementary labeled DNA with platinum‐containing guanine derivative

25-Jan-2016 | Alexandre Loukanov, Chavdar Filipov, Polina Mladenova, Svetlin Toshev, Saim Emin, Microscopy Research and Technique, 2016

ABSTRACT The object of the present report is to provide a method for a visualization of DNA in TEM by complementary labeling of cytosine with guanine derivative, which contains platinum as contrast‐enhanced heavy element. The stretched single‐chain DNA was obtained by modifying double‐stranded ...


Electromembrane extraction of gonadotropin‐releasing hormone agonists from plasma and wastewater samples

22-Jan-2016 | Saeed Nojavan, Tina Bidarmanesh, Ali Mohammadi, Saeid Yaripour, ELECTROPHORESIS, 2016

In the present study, for the first time electromembrane extraction (EME) followed by high performance liquid chromatography (HPLC) coupled with ultraviolet (UV) detection was optimized and validated for quantification of four Gn‐RH agonist anticancer peptides (alarelin, leuprolide, buserelin ...


Re‐evaluation of Sn(II)‐Br− Speciation in Concentrated Bromide Media by Cyclic Voltammetry

21-Jan-2016 | Dasom Park, Jinho Chang, Electroanalysis, 2016

Abstract We report re‐evaluated Sn(II)‐Br− speciation by cyclic voltammetry on a glassy carbon (GC) electrode in concentrated Br− aqueous solutions. Contrary to the previous reports, electrochemical evidences of Sn(II)Br53−, Sn(II)Br64−, Sn(II)Br75−, and Sn(II)Br86− were found in aqueous ...


Molecularly imprinted ionic liquid magnetic microspheres for the rapid isolation of organochlorine pesticides in environmental water

21-Jan-2016 | Fengxia Qiao, Mengmeng Gao, Hongyuan Yan, Journal of Separation Science, 2016

A new type of molecularly imprinted ionic liquid magnetic microspheres was synthesized by aqueous suspension polymerization, using 4,4'‐dichlorobenzhydrol as a dummy template, and 1‐allyl‐3‐ethylimidazolium hexafluorophosphate and methacrylic acid as co‐functional monomers. The results of ...


Bi‐directional AC electrothermal micropump for on‐chip biological applications

21-Jan-2016 | Reza Hadjiaghaie Vafaie, Habib Badri Ghavifekr, Harald Lintel, Juergen Brugger, Philippe Renaud, ELECTROPHORESIS, 2016

The ability to control and pump high ionic strength fluids inside microchannels forms a major advantage for clinical diagnostics and drug screening processes, where high conductive biological and physiological buffers are used. Despite the known potential of AC Electrothermal (ACET) effect in ...
