Abstract

The invention relates to a polymicrobial detection device using quantum dot nanocrystal complexes and a detection method therefor.  One aspect of the invention provides a nanocrystal-microbial attractant complex, for which a microbial attractant for attracting microbes is coupled to a nanocrystal containing one or more element selected from a metal group consisting of zinc, cadmium, lead, copper, gallium, arsenic, thallium, nickel, manganese and bismuth, and a preparation method therefor.  Further, the invention provides a polymicrobial detection method based on the electrochemical analysis that involves the use of a detection kit for detecting microbes using said nanocrystal-microbial attractant complex, and the SWASV (Square wave anode stripping voltammetric) method using said detection kit.
