摘要：
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.
