Maracells provides a platform for continuous online glucose monitoring across all phases of cell culturing

Our innovative and patented optical sensor technology allows user to measure glucose and other analytes and get data faster, easier and continuously during the entire cell culturing process.

Current focus is on glucose measurement in a low-volume cell culturing, providing a solution for a data-driven decision making in the early cell growth phase.


Our sensor technology is a product of combining nanotechnology with chemistry and optics. By special functionalization of single-walled carbon nanotubes (SWCNT), used as sensing material, spectral properties of this nanomaterial can be utilized. Upon appropriate optical excitation signal focused on the sensing material, a response in near-infrared spectrum can be monitored with dedicated photodiodes. Changes in the emitted spectrum can be directly translated to the concentration of analyte present in the matrix.

Single-walled Carbon nanotubes (SWCNT) & biosensors

Carbon nanotubes are a quasi one dimensional, multifunctional nanomaterial with outstanding electrical, optical and chemical properties due to large specific surface area, ultrahigh lent/diameter ratio and easy chemical functionalization. Single-walled carbon nanotubes have all atoms on the surface and show inherently stable fluorescence which presents a great potential for high-performing biosensors by appropriate surface functionalization.
SWCNT-based biosensors exploit carbon nanotubes as an optical transducer and require an analyte-specific surface coating. In the presence of the analyte, a concentration is converted into a detectable optical signal, detected by a reader.
