Abstract
⺠AuNPs/PDDA/MWCNTs nanocomposites were used for the construction electrochemical biosensors. ⺠Suitability of single and bienzyme biosensors was demonstrated, taking cholesterol as analyte. ⺠This platform allows to use extremely simple enzymes immobilization with no need of covalent bonds. ⺠The use of estabilized strategies to avoid potential interferences in real samples is feasible. ⺠Human sera spiked with cholesterol at physiological levels were analyzed with good results.
