“…The change of color of the gold solution after the additional Sarang semut extract from yellow to red wine (Vijayaraghavan, 2017) indicates the occurrence of reduction reaction of gold which transformed Au 3+ ) to Au 0 confirminf the successful formation gold nanoparticles (Figure 1). This phenomenon has been reported by several several reported work in the synthesis of gold nanoparticles, including Fachrurrazie and Wibowo (2017) whose obtained a gold nanoparticle of red-wine color using of sodium citrate and Ahmad, et al (2016) by using coconut leaf oil extract (Elaise guineensis).…”

Abstract. Gold nanoparticles have been synthesized with simple and relatively safe method by using kaemferol and quercetin containing aqueous extract of Myrmecodia pendans (sarang semut plant). Under this method, it was able to obtain AuNPs and measured the size. The formation of the nanoparticles were identified by the color change (yellow to red) occurred in the chloroauric acid solution after additional aquoeos extract of sarang semut plant. The UV-Visible spectra and particle size analyzer indicated the successful formation of AuNPs with wavelength of 521.5 nm which was stable for 4 days, evidenced by the presence of particles with a size 53.2 nm. XRD analysis showed the difractogram peak of gold nanopartcle. The result of SEM analysis indicated gold nanopartcle surface with spherical and rod-like shapes. Glucose sensor utilized gold nanopartcle as catalyst with measurement range 2–5 mM and regresision 0,868, detection limit of sensor was in concentration 2-5 mM was 7,5 mM with sensitivity 0,736 A.mM-1.mm-2. Glucose concentration obtained in blood serum was 78,48mg/dL. Gold nanoparticles is promising to detect blood sugar with simply, securely, low cost without using enzyme and harmful material.

Background and purpose: The increase in diabetes cases has become a major concern in the healthcare sector, necessitating the development of efficient and minimal diagnostic methods. This study aims to provide a comprehensive examination of electrochemical biosensors for detecting diabetes mellitus biomarkers, with a special focus on the utilization of carbon-based electrodes. Review approach: A detailed analysis of electrochemical biosensors incorporating various carbon electrodes, including screen-printed carbon electrodes, glassy carbon electrodes, and carbon paste electrodes, is presented. The advantages of carbon-based electrodes in biosensor design are highlighted. The review covers the detection of several key diabetes biomarkers, such as glucose, glycated hemoglobin (HbA1c), glycated human serum albumin (GHSA), insulin, and novel biomarkers. Key results: Recent developments in electrochemical biosensor technology over the last decade are summarized, emphasizing their potential in clinical applications, particularly in point-of-care settings. The utilization of carbon-based electrodes in biosensors is shown to offer significant advantages, including enhanced sensitivity, selectivity, and cost-effectiveness. Conclusion: This review underscores the importance of carbon-based electrodes in the design of electrochemical biosensors and raises awareness for the detection of novel biomarkers for more specific and personalized diabetes mellitus cases. The advancements in this field highlight the potential of these biosensors in future clinical applications, especially in point-of-care diagnostics.
