In this work, a non-enzymatic chemiresistive sugar sensor has been developed by combining a synthetic receptor with aligned single-walled carbon nanotubes (SWNTs) device. Briefly, boronic acid as a multivalent sugar receptor was immobilized on carbon nanotubes through amide bond formation. The interaction between three common sugars (d-glucose, d-fructose and sucrose) and boronic acid modified SWNTs...
The current work involves fabrication, characterization and subsequent evaluation of poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid) (PEDOT:PSS) coated single walled carbon nanotubes (SWNTs) sensors for detecting analytes of interest in industrial manufacturing. By varying the conducting polymer׳s synthesis conditions in terms of charge controlled electropolymerization of the...
A simple method for preparing bio-functionalized soluble single-walled carbon nanotubes (SWNTs) is described. Different proteins such as bovine serum albumin (BSA), cytochrome c and horseradish peroxidase (HRP) were used to solubilize low functionality SWNTs in water aided by sonication. The unbound proteins were removed by column chromatography and the SWNT-protein conjugate was used as the sole...
