Sensor having sensing surface of three-dimensional structure, and method of forming and using the sensor

摘要

Embodiments of the present invention are directed to a sensor including a sensing circuit and a probe communicatively coupled to the sensing circuit. The probe is coated with a recognition element and is configured to generate a first measurement value based at least in part on a three-dimensional (3D) sensing surface that interacts with a given material. Including the detection surface. In some embodiments, the 3D sensing surface is shaped as a pyramid, cone, or cylinder to increase the sensing surface area on the two-dimensional (2D) sensing surface. In some embodiments, the 3D sensing surface facilitates penetration of the 3D sensing surface through the walls of living cells. [Selection diagram] Figure 1
