VUB scientist receives European grant of €1.5 million

By using carbon-based materials, Vermeulen is working to improve the energy efficiency of lasers on a chip that emit a wide variety of colours, making them fit for large-scale applications. The light sources on chips could be used for biomedical purposes, for example, making sure that diabetes patients no longer have to take a blood sample to check their sugar levels. Instead of pricking themselves with needles, patients would only need to hold the chip against their skin. The chip could possibly also serve to detect the contamination of drinking water.
