Pre Seed · Biotech · Gothenburg, Sweden · Founded 2023 · 7–7 employees

LayerLogic develops innovative biosensing technology based on graphene field-effect transistors (gFETs) for rapid detection of bacteria, viruses, fungi, and contaminant molecules in food. Their portable biosensor delivers digital test results in under 15 minutes compared to 2-4 days required by traditional methods, with sensitivity comparable to PCR tests. The company raised €470,000 in pre-seed funding in 2025 led by Scientifica Venture Capital and emerged as a spin-off from Chalmers University of Technology's Department of Quantum Device Physics. Their technology addresses critical food safety challenges while reducing waste and supporting sustainable production practices.
