“…Among the wide range of analytical techniques available, electrochemical analysis proves to be a versatile tool for H 2 O 2 detection owing to its speed, affordability, simple instrumentation, and high sensitivity [48]. Recently, various metal composites for H 2 O 2 detection with high performance have been introduced [49][50][51]. Furthermore, metal nanoparticles such as electrodeposited Cu exhibit remarkable catalytic activity in the electrochemical determination of H 2 O 2 [52].…”

A copper-modified indium tin oxide (ITO) electrode was utilized as an electrocatalytic sensing platform for hydrogen peroxide (H2O2) detection. In this study, instead of conventional solution-phase electrodeposition, electrochemical deposition was used to deposit Cu on an ITO electrode with agarose hydrogel. The hydrogel-based Cu nanoparticles exhibited a more evenly dispersed distribution compared to those in the solution phase. Additionally, by incorporating agarose hydrogel as a solid electrolyte, the overall active surface area of Cu nanoparticles on the electrode surface was increased, mainly resulting from a decrease in the aggregation of Cu nanoparticles. Cyclic voltammetry and chronoamperometry confirmed that the resulting Cu nanoparticles possessed distinct electrocatalytic activity for H2O2 reduction and good selectivity for various interfering substances. The chronocoulometry response of the fabricated sensor obtained at −0.6 V (vs. Ag/AgCl) increased linearly with a dynamic range of 1–500 μM, and the limit of detection for H2O2 was 1.73 μM. Our research provides new possibilities for the electrochemical synthesis of metal nanoparticles for non-enzymatic sensing applications.

This study aims to develop bacterial cellulose with enhanced flame retardancy and flexibility. The bacterial cellulose was phosphorylated with phytic acid to improve its flame retardancy. Urea and xylitol were used as plasticizers, and their effects in improving the flexibility of bacterial cellulose were compared and evaluated. The optimal conditions for producing phosphorylated bacterial cellulose were found to be as follows: phytic acid:xylitol molar ratio of 1:10, phytic acid concentration of 10% (o.w.f.), and shaking at 30°C for 30 min at 90 rpm in a shaking water bath. A thermogravimetric analysis revealed that phosphorylated bacterial cellulose exhibited enhanced thermal properties compared with the original bacterial cellulose. Fourier transform infrared spectroscopy and X-ray diffraction confirmed that the chemical and crystalline structures of bacterial cellulose remained unchanged after phosphorylation. Mechanical properties such as the tensile strength, flexibility, and dimensional stability of the as-produced phosphorylated bacterial cellulose improved by using xylitol. In particular, the tensile strength and flexibility of the phosphorylated bacterial cellulose increased 5.7 and 2-fold, respectively, compared with those of the original bacterial cellulose. Therefore, this study demonstrated that the flame retardancy and flexibility of bacterial cellulose can be improved by using eco-friendly materials such as phytic acid and xylitol. The as-produced phosphorylated bacterial cellulose can be proposed as a fabric material with sufficient mechanical properties.
