The development of new methods and concepts to visualize massive amounts data holds the promise revolutionize way scientific results are analyzed, especially when tasks such as classification clustering involved, in case sensing biosensing. In this paper we employ a suite software tools, referred PEx-Sensors, through which projection techniques used analyze electrical impedance spectroscopy electronic tongues related sensors. possibility treating high dimension datasets with PEx-Sensors is...
Abstract We report on immunosensors to detect D-dimer, a biomarker of venous thromboembolism, which are made with layer-by-layer (LbL) films containing immobilized anti-D-dimer monoclonal antibody alternated layer chitosan/gold nanoparticles (AuNpChi). Detection was due irreversible adsorption the antigen D-dimer its corresponding according Langmuir-Freundlich model, thus giving rise ellipsoidal structures in scanning electron microscopy images whose size and number increased concentration....
This paper reports the surface activity of phytase at air−water interface, its interaction with lipid monolayers, and construction a new phytic acid biosensor on basis Langmuir−Blodgett (LB) technique. Phytase was inserted in subphase solution dipalmitoylphosphatidylglycerol (DPPG) Langmuir incorporation to interface monitored pressure measurements. able incorporate into DPPG monolayers even high pressures, ca. 30 mN/m, under controlled ionic strength, pH, temperature. Mixed were...
A direct, low-cost method to determine the concentration of lactose is an important goal with possible impact in various types industry. In this study, a biosensor reported that exploits specific interaction between and enzyme β-galactosidase (β-Gal) normally employed process into glucose galactose for lactose-intolerant people. The was made β-Gal immobilized layer-by-layer (LbL) films polyelectrolyte poly(ethylene imine) (PEI) poly(vinyl sufonate) (PVS) on indium tin oxide (ITO) electrode...
The peptide NS5A-1 (PPLLESWKDPDYVPPWHG), derived from hepatitis C virus (HCV) NS5A protein, was immobilized into layer-by-layer (LbL) silk fibroin (SF) films. Deposition monitored by UV-vis absorption measurements at each bilayer deposited. interaction SF/peptide film induced secondary structure in as indicated fluorescence and circular dichroism (CD) measurements. Voltammetric sensor (SF/NS5A-1) properties were observed when the composite tested presence of anti-HCV. peptide-silk studied...
Impedance spectroscopy has been proven a powerful tool for reaching high sensitivity in sensor arrays made with nanostructured films the so-called electronic tongue systems, whose distinguishing ability may be enhanced sensing units capable of molecular recognition. In this study we show that optimized sensors and biosensors dielectric relaxation processes involved impedance measurements should also considered, addition to an adequate choice materials. We used from layer-by-layer (LbL)...
Control of supramolecular architectures inherent in layer-by-layer (LbL) films allows for synergistic effects between the film components, as reactions under controlled conditions. In this paper we show that a bienzyme system can be produced LbL films, which product reaction catalyzed by invertase (INV) is used catalysis process involving glucose oxidase (GOx). As proof principle, simultaneous detection and sucrose demonstrated an optimized architecture comprising poly allyllamine...
