“…Since H 2 O 2 is a crucial small molecular biomarker in cancer studies [41,42], and precise quantitative determination of H 2 O 2 in biological and environmental samples holds paramount importance [43,44], in this study we conducted an in-depth investigation into the electrochemical catalytic activity of Pt&Pd-NPs-NPG/GP towards H 2 O 2, with Pt-NPs-NPG/GP and Pd-NPG/GP as the control samples. Figure 4A exhibits the characteristic cyclic voltammetry (CV) curves obtained from different modified GP electrodes when immersed in a testing solution of PBS (0.1 M, pH 7.4) with 20 mM H 2 O 2 under optimal detection conditions.…”

The exploration into nanomaterial-based nonenzymatic biosensors with superb performance in terms of good sensitivity and anti-interference ability in disease marker monitoring has always attained undoubted priority in sensing systems. In this work, we report the design and synthesis of a highly active nanocatalyst, i.e., palladium and platinum nanoparticles (Pt&Pd-NPs) decorated ultrathin nanoporous gold (NPG) film, which is modified on a homemade graphene paper (GP) to develop a high-performance freestanding and flexible nanohybrid electrode. Owing to the structural characteristics the robust GP electrode substrate, and high electrochemically catalytic activities and durability of the permeable NPG support and ultrafine and high-density Pt&Pd-NPs on it, the resultant Pt&Pd-NPs–NPG/GP electrode exhibits excellent sensing performance of low detection limitation, high sensitivity and anti-interference capability, good reproducibility and long-term stability for the detection of small molecular biomarkers hydrogen peroxide (H2O2) and glucose (Glu), and has been applied to the monitoring of H2O2 in different types of live cells and Glu in body fluids such as urine and fingertip blood, which is of great significance for the clinical diagnosis and prognosis in point-of-care testing.
