Abstract
A specific bonding analysis method by which sensitivity and concentration range in analysis can be freely set, and a device using this are provided. The intended analysis is optimized by using a specific bonding analysis device capable of controlling the velocity of a sample passing through a detection part and causing no remaining of unnecessary components on a detection part.
Claims17
A specific bonding analysis method comprising the steps of:
- preparing a specific bonding analysis device comprising a sample adhering part for adding a liquid sample containing an analyte, a space forming part exerting capillary phenomenon connected with said sample adhering part and a detection part capable of detecting a signal derived from a specific bonding reaction in said space forming part;
- making said sample adhere to said sample adhering part to transfer said sample into said detection part in said space forming part by capillary phenomenon, thereby causing a specific bonding reaction;
- detecting a signal derived from the specific bonding reaction to qualify or quantify said analyte;
- and
- controlling liquid transportation force by capillary phenomenon in said space forming part in the downstream side from said detection part along the transferring direction of said sample.
