Abstract:
The present invention provides a sensor including a detection unit having a detection electrode and a polymer layer that is disposed on the detection electrode and includes a mold having a three-dimensional structure complementary to a steric structure of a microorganism to be detected. The sensor detects the microorganism based on a state of capturing the microorganism in the mold. The polymer layer is formed by a manufacturing method including: a polymerization step of polymerizing a monomer in the presence of the microorganism to be detected, to form the polymer layer having captured the microorganism on the detection electrode; a destruction step of partially destroying the microorganism captured in the polymer layer; and a peroxidation step of peroxidizing the polymer layer to release the microorganism from the polymer layer.
Abstract:
A detection device (100) detects an analyte that may be contained in a specimen. The detection device (100) includes a plurality of gold nanoparticles, an optical trapping light source (101), an illumination light source (102), an objective lens (103), an image pick-up device (108), and a computation unit (106). The plurality of gold nanoparticles are each modified with a probe DNA allowing the analyte to specifically adhere thereto. The optical trapping light source (101) emits polarized light for assembling the plurality of gold nanoparticles together. The objective lens (103) focuses and introduces the polarized light into a liquid containing a specimen and the plurality of gold nanoparticles. The image pick-up device (108) receives light from the liquid. The computation unit (106) detects an analyte based on a signal received from the image pick-up device (108).
