According to the World Health Organization (WHO), 600 million people worldwide are affected by food poisoning each year – almost 1 in 10 – of whom 420,000 die
To meet this need, a research team led by Professor Hiroshi Shiigi of the Graduate School of Engineering of Osaka Metropolitan University used the optical properties of organometal NHs – a composite material composed of polyaniline particles that encapsulates a large number of metal nanoparticles – to quickly and simultaneously identify intestinal hemorrhagic Escherichia coli (E.
The team first found that organometallic NHs produce more scattered light than metal nanoparticles of the same size
The research team then binds specifically to E.
This method can identify various types of bacteria
Professor Shiigi said: "Our goal is to establish new detection principles and test methods by developing unique nanobiomatrials
