A field‐effect transistor (FET) based on ultrathin Ti 3 C 2 –MXene micropatterns is developed and utilized as a highly sensitive biosensor. The device is produced with the microcontact printing technique, making use of its unique advantages for easy fabrication. Using the MXene–FET device, label‐free probing of small molecules in typical biological environments and fast detection of action potentials in primary neurons is demonstrated.
