A Gold Nanoparticles-Enhanced Carbon Nanotubes Electrochemical Chiral Sensor

The field of enantioselective recognition directly using inherently chiral single-walled carbon nanotubes (cSWCNTs) still remains unexplored. Herein, the insertion of size-controlled gold nanoparticles (GNPs) to cSWCNTs brings about superior conductivity, high stability, and excellent electrocatalytic ability, thus an enhanced sensitivity for chiral sensing. The practicability of the GNPs/cSWCNTs based electrochemical sensor was validated by chirally recognizing 3,4-dihydroxyphenylalanine and tyrosine as model molecules.National Natural Science Foundation of China (NSFC) [21475002, 21335001, 21175006]SCI(E)ARTICLE4955-9592
