    摘要: A capacitive chemical sensor, along with methods of making and using the sensor are provided. The sensors described herein eliminate undesirable capacitance by etching away the substrate underneath the capacitive chemical sensor, eliminating most of the substrate capacitance and making changes in the chemical-sensitive layer capacitance easier to detect.
