AI Technical Summary

Technical Problem

Existing technologies require a culture process when detecting bacteria and viruses, which leads to delayed results and high costs. They also cannot detect multiple bacteria and viruses simultaneously and rapidly. Existing methods such as colony counting, bioluminescence, and PCR cannot meet the needs for rapid quantification and multi-item detection.

Method used

By employing an electrode chip with two or more metal nanostructures attached, the peak current value is measured by applying voltage, and the target is determined by combining data storage and comparison, thus enabling the simultaneous detection and quantification of multiple bacteria and viruses.

Benefits of technology

It enables rapid, quantitative, and highly selective detection of a variety of bacteria and viruses, reducing testing costs and simplifying the operation process.

Abstract

The present application provides a device for making labels corresponding to respective kinds of bacteria or viruses, and detecting bacteria and / or viruses in a test object based on the properties of the labels. A DPV detection device (1) includes: an electrode chip (20); a voltage application unit (105) that applies a voltage in a prescribed range to the electrode chip (20); a current measurement unit (106) that measures a peak current value output from the electrode chip (20) in correspondence with the applied voltage; a data storage unit (107) that stores in advance data of peak current values and applied voltage values at the time of peak current for respective kinds of metal nanostructures; a target determination unit (108) that compares the measured data of the current measurement unit (106) with the stored data, and determines a target that binds to the metal nanostructure; and a display unit (103) that displays the determined target.
