Abstract

Neurotransmitters being the signalling molecules are crucial for normal brain functions and their imbalance is associated with a number of mental health diseases. Therefore precise detection and measurement of these molecules are essential in diagnosis of different brain disorders and research studies. Although various techniques have been suggested for their analysis but their specific detection and measurement is a challenging task because of their presence in lower concentrations in central nervous system and mixing with other biochemical substances and it is still an area of ongoing research. This paper discusses the conventional methods and also most recent advances and developments in the detection techniques of neurotransmitters such as electrochemical and nano-object sensing techniques with the goal to provide selection guidelines for diagnosis of diseases and research.
