Determination of the biomarker L-tryptophan level in diabetic and normal human serum based on an electrochemical sensing method using reduced graphene oxide/gold nanoparticles/18-crown-6

A novel nanocomposite-modified electrode based on reduced graphene oxide (rGO) decorated with 18-crown-6 (Cr.6) and gold nanoparticles (GNPs) on the surface of a glassy carbon electrode (GCE) was successfully fabricated to investigate the electrochemical sensing of the biomarker L-tryptophan (L-Trp)...
