Rebecca Trager meets an organic chemist catalysing the search for BPA replacements by connecting synthetic chemists, data scientists, toxicologists and polymer chemists
Finding a replacement for the endocrine disruptor bisphenol A (BPA) was never going to be solved by synthesis alone and Helena Lundberg from KTH Royal Institute of Technology in Sweden knew that from the start. Designing a molecule is one thing; demonstrating that it is safe and performs reliably in a polymer is another.
