Electrochemical sensing of sildenafil in pharmaceutical formulations using an (S,N)-doped reduced graphene oxide-modified electrode

In this work, (S,N)-co-doped reduced graphene oxide ((S,N)-rGO) was successfully synthesized via thermal treatment and thoroughly characterized by X-ray diffraction, high-resolution transmission electron microscopy, elemental mapping, photoluminescence, and Raman spectroscopy, confirming the successful incorporation of...

Synthesis and application of ZnO/chitosan oligosaccharide/humic acid derived from natural peat

This study reports the synthesis of a ZnO/chitosan oligosaccharide/humic acid-rich fraction (ZnO/COS/HA) bioformulation based on zinc oxide particles consisted of nanosized crystallites (11.4–23.7 nm) assembled into larger submicron rod-like particles stabilized by chitosan oligosaccharides and humic acid derived from...
