“…At the same time, sodium alginate is also a renewable resource with certain biocompatibility, non-toxic and low cost [ 27 , 28 ]. Although many literatures have reported the metal nanoparticles doped on graphene, toxic reducers and stabilizers have been used [ 19 , 29 ].…”

In this work, a facile, environmentally friendly method was demonstrated for the synthesis of Ag-Au bimetallic nanoparticles (Ag-AuNPs) supported on reduced graphene oxide (RGO) with alginate as reductant and stabilizer. The prepared Ag-AuNPs/RGO was characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The results indicated that uniform, spherical Ag-AuNPs was evenly dispersed on graphene surface and the average particle size is about 15 nm. Further, a non-enzymatic sensor was subsequently constructed through the modified electrode with the synthesized Ag-AuNPs/RGO. The sensor showed excellent performance toward H2O2 with a sensitivity of 112.05 μA·cm−2·mM−1, a linear range of 0.1–10 mM, and a low detection limit of 0.57 μM (S/N = 3). Additionally, the sensor displayed high sensitivity, selectivity, and stability for the detection of H2O2. The results demonstrated that Ag-AuNPs/RGO has potential applications as sensing material for quantitative determination of H2O2.

Sodium alginate (SA) hydrogels crosslinked by calcium carbonate (CaCO3) and gluconolactone (GDL) were prepared, and were characterized by X‐ray diffraction (XRD) analysis and Fourier transform infrared (FTIR) spectrometer. The morphologies of the gel were observed with scanning electron microscopy (SEM). The SA hydrogels were used as carrier of the anti‐inflammatory drug IBU. The effects of GDL content, pH value and temperature on IBU release behavior were investigated and associated kinetic analysis was performed. The results showed that the cumulative release of IBU showed a trend of increasing and then decreasing with GDL content increased. The maximum cumulative release was observed when the molar ratio of Ca2+ in CaCO3 to GDL was 0.6. The release behavior of IBU was observed to have been influenced by pH levels, and it exhibited an optimal release trend at a pH value of 7.4. The impact of temperature on the release behavior of IBU was relatively insignificant compared to other factors. The Korsmeyer‐Peppas release kinetic model was well fitted, and suitable to explain the release behavior of IBU from the sodium alginate hydrogel.This article is protected by copyright.
