dc.description.abstract© 2022, The Author(s), under exclusive licence to Springer Nature B.V.This work describes the synthesis, characterization, and electrochemical application of hybrid PdNPs/carbon dots/silica nanostructures, in which palladium nanoparticles (PdNP) were directly obtained through the carbon dots reduction by only one step. These nanostructures were characterized by UV–vis spectroscopy, FTIR with ATR module, HR-TEM, SEM, AFM, XPS, and electrochemical impedance. A non-enzymatic biosensor was prepared by dispersing the PdNPs/carbon dots/silica nanostructures on a printed carbon electrode, exhibiting excellent electrocatalytic activity for the simultaneous determination of dopamine and serotonin with a detection limit of 36 and 33 nmol L−1, respectively. The detection of dopamine and serotonin was also performed in real samples and did not suffer significant interference from ascorbic acid (AA) or uric acid (UA).
