Acetylcholine receptor-based biosensor derived from Asian swamp eel, Monopterus albus for heavy metals biomonitoring

Cholinesterase-based biosensor well known as a sensitive method to detect the existence of harmful dissolved compounds in any type of water source, especially the river. This alternative biosensor can be used to determine the level of pollution of the water in a short period of time as well as to ev...
