Ion-Sensitive Field-Effect Transistor Technology

Ion-Sensitive Field-Effect Transistor (ISFET) Technology is an analytical chemistry technique that employs solid-state devices to measure ion concentration and infer pH levels in solutions. ISFET sensors consist of a metal-oxide semiconductor sensitive to hydrogen ions (H+). As the ion concentration in the solution changes, it affects the electrical properties of the sensor, causing measurable shifts in current or voltage. This technique is particularly valuable in applications where rapid, accurate, and continuous pH measurements are required, such as environmental monitoring, biotechnology, and medical diagnostics. Our services based on ISFET Technology offer precise pH measurements and monitoring to meet the specific needs of industries like healthcare, food and beverage, and environmental science, contributing to better quality control and research.
