A Korean research team has developed a microdroplet device based on surface-enhanced Raman spectroscopy capable of detecting Yersinia pestis, a bacterium transmitted from rodents to humans by the bite of infected fleas.

The microdroplet device can generate extremely tiny droplets in microchannels, and automatically analyze various material responses, and surface-enhanced Raman spectroscopy is a test that uses a phenomenon which amplifies Raman scattering signals caused by light reflecting from material by 100 to 1,000 times on the surface of metals.

This microdroplet device allows for detecting bacteria in a fast, safe and highly sensitive manner.

Professor Chu Jae-Beom주재범 of Hanyang University jointly researched with the Korea Centers for Disease Control & Prevention (KCDC) and found a new methodology for detecting high-risk pathogens on the spot in a fast, safe and highly sensitive manner.

KCDC is currently developing and distributes bioterrorism agent and toxin multi-detection kit (9 kinds) using immunochromatographic assays, as well as next-generation on-site detection technology with fast speed and high sensitivity, using Raman and nano fusion technology.

As the new technology allows for pathogen detection within the device, it can prevent the outflows of a pathogen in the course of the test, securing its reproducibility and stability as well.

The results of the study were published in the August issue of Analytical Chemistry, a prominent international academic journal published by the American Chemical Society.
