A simple amino-functionalization method for carbon nanotubes and its application in an electrochemical immunosensor for detection of the human cardiac troponin T are described. Amino-functionalized carbon nanotubes allow oriented antibodies immobilization via their Fc regions, improving the performance of an immunosensor. Herein multiwalled carbon nanotubes were amino-functionalized by using th...

Ralph Stanton was born in Ontario, Canada, on the anniversary of the Battle of Trafalgar, and he died in St Boniface hospital in Winnipeg, at the age of 86. He preferred a simple life, content with a shelf of good books, his stamp collection, a little good food, congenial company, and an interesting problem on which to work. Stanton graduated with a PhD in Mathematics in 1949, and began his tea...

Nickel (II) preconcentration and speciation analysis using a hollow fiber supported liquid membrane (HFSLM) device was studied. A counterflow of protons coupled to complexation with formate provided the driving force of the process, while Kelex 100 was employed as carrier. The influence of variables related to module configuration (acceptor pH and carrier concentration) and to the sample proper...

abstract the decisions and personal preferences of the designer are vital for all aspects and stages of the design. to elaborate, the designer has the central role in creation, development, detailing and construction of the built forms. also, the scientific/engineering evaluations of the design models are carried out under the directions and decisions of the designer. the paper explores the con...
