Abstract:
In this work, a gold nanoparticle (AuNPs)-embedded bacterial cellulose nanopaper was synthesized. The bare nanopaper was prepared by culturing of Acetobacter xylinum in Hestrin-Schramm (culture medium). A piece of the bare nanopaper (8 mm O and 5-mm thickness) was used as a reducing reagent and a substrate for the 'in-situ' embedding of AuNPs by dipping into the boiled solution of 50 mmol L-1 HAuCl4. After 90 min, color of the nanopaper was changed from pale yellow to wine-red. The results obtained by energy dispersive x-ray spectrometer showed that 97.3 percent Au0 was occurred. The as-prepared nanopaper was applied as a 2D-microcuvette for the colorimetric detection of H2O2. Detection principle is based on the redox reaction between Au0 and H2O2 in the acidic medium. After dropping of 100 muL of standard H2O2 and 400 muL of 20 mmol L-1 acetate buffer (pH 6.0) onto the as-prepared nanopaper, its wine-red color turned pale. This led to decreasing in the absorbance reading at 525 nm, measured by a 'thin-film' UV spectrophotometer. A linear calibration plot between absorbance and the concentration of standard H2O2 was constructed. Linearity range up to 20 percent H2O2 was achieved with good linearity (r2 > 0.98) and high precision (2.5 percent RSD). The developed method was applied to determine the H2O2 content in wound cleaner. The result was not difference from the label concentration.
