USE OF MULTI-WALLED CARBON NANOTUBES FOR ANALYSIS OF NEUROTRANSMITTERS

摘要

Introduction Biosensors represent the most exciting application area in nanotechnology since are extremely sensitive, selective, reactive and they can replace the more costly and tedious laboratory methods for checking patient's blood for proteins, chemicals, and pathogens in medical diagnostics area. For development of electrochemical biosensors, multi-walled carbon nanotubes (MWCNTs) are usually used because of their numerous benefits, namely the great electrochemically accessible surface area, the rich functionalization chemistry, the high electrical conductivity, as well as the attractive mechanical properties. Furthermore, MWCNTs can be successfully used as non-enzymatic sensors for selective detection of biomolecules with high sensitivity and stability.
