A novel dual-functional biosensor for fluorometric detection of inorganic pyrophosphate and pyrophosphatase activity based on globulin stabilized gold nanoclusters
A novel dual-functional biosensor for the detection of PPi and PPase is developed. The biosensor provides a low detection limit for PPi and PPase. The biosensor can be used for the assaying of PPase activity in human serum. Globulin protected gold nanoclusters with excellent stability are synthesized.
