Pleased to have been given an award for the most outstanding presentation at the BRC symposium at St Anne's College. My talk was on "Identification of substandard and falsified vaccines using a panel of low-cost tests". @BiochemOxford @KavliOxford

NEW: An international team of researchers led by Oxford University and Oxford University Hospitals NHS Foundation Trust have demonstrated that hospital analysers can be used to identify fake liquid medical products.

In case you missed it... our very own Dr Bevin Gangadharan speaks about why it's so important not only that detection of contaminants in eg medicinal syrups is available but is also low-cost and rapid.👏👏👏
Thank you @TTVOxfordshire. We have repurposed simple, rapid and low-cost tests (saliva/breastmilk alcohol strips and disposable breathalysers) to help prevent child deaths from contaminated medicinal syrups.
Note: The strips are less than £1 (I accidentally said under £10).
Bevin Gangadharan retweeted
"The reasons why these toxic ingredients happen to be found in syrups are various. They are intentional and nonintentional cases."
That's TV spoke to Celine Caillet about how she hopes the test will prevent tainted medicine from reaching young children.

Pleased that our paper has been published where we repurpose rapid, low-cost tests to help prevent child deaths from contaminated medicinal syrups.
Thanks to @benedict_yohan, @zitzmann_nicole and rest of the DEG-EG team in Oxford.
NEW: Researchers have shown that simple, rapid, and low-cost tests can detect deadly contaminants in medicinal syrups – the same contaminants linked to the deaths of hundreds of children worldwide.
They repurposed existing rapid tests, each costing under £1.

Low-cost, rapid tests like alcohol test strips & breathalysers can detect toxic contaminants in medicinal syrups
@IDDOnews
With over 300 child deaths worldwide linked to syrup contamination, these simple tools could save lives.

Simple, rapid, inexpensive tests can detect deadly contaminants in medicinal syrups – contaminants that have tragically led to the deaths of hundreds of children worldwide. The discovery was made by researchers here @UniofOxford and collaborators. ➡️Read bit.ly/202512_gangadharan
ALT This flow chart demonstrates how metabolic pathways of PG and glycerol are used as excipients in syrups and DEG/EG, including the use of glycolate oxidase for the detection of glycolic acid. To simplify this pathway, steps with NAD+ and NADH have been omitted.
