COMPETITIVE IMMUNOCHROMATOGRAPHIC ANALYSIS METHOD AND IMMUNOCHROMATOGRAPHIC SENSOR

[Problem to be Solved by the Invention] The purpose of the present invention is to provide a competitive immunochromatographic analysis method and immunochromatographic sensor using said analysis method capable of intuitively displaying a molecular concentration of a substance to be measured and facilitating visual judgement of the molecular concentration. [Problem to be Solved by the Invention] Competitive immunochromatographic analysis method according to the present invention is characterized in that the method comprises a step for supplying a mixed solution, in which a test solution containing a substance to be measured A and a labeled antibody B are mixed, to one or more judgement parts wherein said judgement parts are formed by immobilizing a text antibody C which specifically reacts with the labeled antibody B specifically reacting with the substance to be measured A on a membrane carrier in the form of character(s) or figure(s) and immobilizing a mask antigen D composed of the same antigen as the substance to be measured A on the membrane carrier so as to surround said text antibody C, a step for competitively binding the labeled antibody B to the substance to be measured A, the mask antigen D and the text antibody C on the judgement parts, a step for judging the concentration of the substance to be measured A based on the signal from the labeled antibody B bound to the text antibody C and the mask antigen D.

Methods and apparatus for a shear-enhanced CNT-assembly nanosensor platform for ultra-sensitive and selective protein detection

A nanoscale protein-sensing platform with a non-equilibrium on-off switch that employs dielectrophoretic and hydrodynamic shear forces to overcome these thermodynamic limitations with irreversible kinetics. The detection sensitivity is achieved with complete association of the antibody-antigen-antibody (Ab-Ag-Ab) complex by precisely and rapidly assembling carbon nanotubes (CNT) across two parallel electrodes via sequential DC electrophoresis and dielectrophoresis (DEP), and with single-CNT electron tunneling conductance. The high selectivity is achieved with a critical hydrodynamic shear rate between the activated dissociation shear rates of target and non-target linkers of the aligned CNTs.
