LayerLogic

LayerLogic is a Swedish deeptech startup, spun out of Chalmers University of Technology, that harnesses graphene-enhanced biosensing technology for rapid, precise bacteria detection.

The Company aims to provide fast, accurate, and reliable detection of harmful bacteria. By combining graphene-based sensor technology (GFET) with advanced biochemistry, it enables food producers and environmental labs to detect contamination quickly and efficiently, reducing risks and ensuring safety.

At the core of the company’s innovation is a portable biosensor that uses graphene field-effect transistors (gFETs) to detect foodborne pathogens. The surface of the sensor is functionalized with selective receptor molecules, enabling rapid identification of bacteria, viruses, fungi, and contaminant compounds. The system provides results digitally in under 15 minutes, compared to the two to four days typically required by conventional lab testing. Designed for direct use on production lines, the compact device aims to help food manufacturers detect contamination early and reduce downtime, waste, and financial loss.

In June 2025, LayerLogic raised €470K to scale its graphene-based food safety sensor.
