💡Implication: the true burden of the smallest, and potentially most harmful plastics has been severely underestimated. This is a step toward understanding how micro- and nanoplastics affect human health. #placenta #publichealth #nanoplastics

Why did we miss this before? Most methods only detect particles >5 µm and lose tissue context. 👉 Our workflow detects down to ~400 nm, avoids contamination, and preserves histology and letting us map plastics. #fluorescence #clearing

🌍Microplastics don’t just surround us, they’re inside us. And they’re plentiful. Our new method reveals thousands to millions of particles per cm³ in human placenta, not just a handful. Preprint 👉 medrxiv.org/content/10.1101/… #microplastics #health #toxicology

Gisteren op factcheckers : Zitten er microplastics in kartonnen drinkbekers? Onderzoek in Roeffaers Lab geeft verduidelijking : vrt.be/vrtnws/nl/2025/02/17/… Herbekijk de uitzending : vrt.be/vrtmax/a-z/factchecke… #microplastics #factcheckers #Research

Drank uit kartonnen bekertjes bevat piepkleine plasticdeeltjes: "Blootstelling zoveel mogelijk...

Kartonnen wegwerpbekers geven minuscule plasticdeeltjes af die via de drank in het lichaam belanden. Dat blijkt uit een test van het programma 'Factcheckers'. Bij hete dranken zoals koffie of thee...

With KU Leuven Inside, the idea to give our students, alumni, and the public at large a unique insight into our university was brought to fruition. And what a success it was!

From phosphors for energy-efficient LEDs 💡 to solar cell layers ☀️, catalysts for cleaner chemistry ⚗️, and the presence of soot and microplastics in food, drinks, and even human tissues 🌱🧬 – we explored the fascinating world of nanomaterials.

Advanced microscopy helps us not only design better materials but also better understand their potential risks. Centuries old, full of life – and still pushing the boundaries of science.

Our team just returned from the inspiring #Micro2024 conference! 🎉 Quinten was the poster king 👑 with his popular work on detecting microplastics in human tissues. Microplastics may be tiny, but the discussions were HUGE! #Microplastics

Last Friday's lunch was a science feast! We were thrilled to have Prof. H. Zhang (Hong Kong City University) and Prof. N. Yan (UHasselt) join us for delicious food and lively scientific discussions with Prof. J. Hofkens and Prof. F. De Schryver. Great minds, great conversations!
