Bayley and Cremer 2001;Coulter 1953). By monitoring the ionic current modulations induced by the passage of analytes of interest through the nanopore at a fixed applied potential, the concentration of the analyte can be obtained by the frequency of occurrence (1/t on ) of the recorded blockage events, while the mean residence time (t off ) of the analyte allows to determine its identity (Zhao et al. 2008). In nanopore sensing, each analyte produces a characteristic signature (t off ), and this allows several analytes to be quantitated simultaneously van Staden and Moldoveanu 2014a, b).Maltodextrins are nanostructured materials with native channels due to their helix structure. Thus they were considered as materials for designing stochastic sensors proposed for the screening of three biomarkers: neuron specific enolase (NSE), carcinoembryonic antigen (CEA) and epidermal growth factor receptor (EGFR/HER-1). Maltodextrins ( Fig. 1) are carbohydrates derived from maize starch and are a group of oligosaccharides (long chainpolysaccharides) composed of glucose, with dextrose equivalent (DE) less than 20. Dextrose equivalent is a measure of reducing power of starch-derived polysaccharides/oligosaccharides compared with d-glucose on a dry-weight basis: the higher the DE, the greater the extent of starch hydrolysis. They are obtained by acidic and/or enzymatic hydrolysis of corn starch, with subsequent drying to make free flowing powders. They usually contain glucose, depending on the degree and method of hydrolysis. Therefore, maltodextrins are also called glucose polymers (Al-Khatib et al. 2001;Preis et al. 2014;Wang and Wang 2000). Along the time, maltodextrins have been used as chiral selectors for separation of the enantiomers of chiral drugs by capillary electrophoresis (Watanabe et al. 1999;Fakhari et al. 2013;D'Hulst and Verbeke 1992), for the design of enantioselective, potentiometric membrane electrodes (EPMEs) Abstract Stochastic sensors based on maltodextrins with different dextrose equivalent were proposed for the assay of three lung cancer biomarkers: neuron specific enolase, carcinoembryonic antigen and epidermal growth factor receptor. The two sensors proposed can determine simultaneously NSE, CEA and HER-1 in whole blood samples (qualitative and quantitative), with recoveries higher than 97.00 %, and low RSD (%), lower than 0.1 %. This screening test may serve for fast and early detection of lung cancer.
