BioColour - Bio-based Dyes and Pigments for Colour Palette

Research group

Natural dyes may contain biologically active compounds which may have harmful effects on human health. The research team lead by Prof. Jaana Rysä of toxicology at the School of Pharmacy UEF will assess toxicity of novel biocolourants. The team includes Postdoctoral Researcher Mikko Herrala and Doctoral Student Johanna Yli-Öyrä. The team studies cell viability, cytotoxicity, skin sensitivity and production of reactive oxygen species in human cell lines. In addition, the team provides expertise for safety evaluation and risk assessment. The ultimate aim is to ensure the safety of novel bio-based dyes and pigments.
