Researchers from University of California Detail Findings in Nanotubes [Poly(3-aminophenylboronic acid)-functionalized carbon nanotubes-based chemiresistive sensors for detection of sugars]

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Nanotubes are presented in a new report. According to news reporting from Riverside, California, by NewsRx journalists, research stated, "The poly(aniline boronic acid) (PABA)-functionalized single-walled carbon nanotube (SWNT) non-enzymatic sensor was developed for the detection of saccharides. The work involved the electrochemical polymerization of 3-aminophenylboronic acid (3-APBA) in the presence of fluoride on the surface of SWNTs and their subsequent evaluation as chemiresistive sensors towards the detection of d-fructose and d-glucose."

The news correspondents obtained a quote from the research from the University of California, "By varying the sensor's synthesis conditions by charge-controlled electropolymerization, the sensing performance was systematically optimized. Through electrical characterization in terms of change in resistance, cyclic voltammetry confirmed the electrochemical deposition of the PABA coating on the SWNTs. The optimized sensors showed sensing response over a wide dynamic range of concentrations and a limit of detection of 2.92 mM for D-fructose and 3.46 mM for D-glucose."

According to the news reporters, the research concluded: "The hybrid sensors could be regenerated on the basis of the reversible nature of the binding between PABA and 1,2-or 1,3-diols at lower values of pH."
