“…For a concentration range of 0.002 to 20 mM H 2 O 2 , the sensitivity of 236 µA mM −1 cm −2 (R 2 = 0.999), the response time of 2 s, and a detection limit of about 0.73 µM were achieved. A Ag-GO nanocomposite was also achieved using Andrographis aniculate extract as the reducing agent, which exhibited excellent sensing ability for H 2 O 2 , with a low detection limit of 2.65 µL and a wide detection range of 0-15 µM [81].…”

Technological progress has led to the development of analytical tools that promise a huge socio-economic impact on our daily lives and an improved quality of life for all. The use of plant extract synthesized nanoparticles in the development and fabrication of optical or electrochemical (bio)sensors presents major advantages. Besides their low-cost fabrication and scalability, these nanoparticles may have a dual role, serving as a transducer component and as a recognition element, the latter requiring their functionalization with specific components. Different approaches, such as surface modification techniques to facilitate precise biomolecule attachment, thereby augmenting recognition capabilities, or fine tuning functional groups on nanoparticle surfaces are preferred for ensuring stable biomolecule conjugation while preserving bioactivity. Size optimization, maximizing surface area, and tailored nanoparticle shapes increase the potential for robust interactions and enhance the transduction. This article specifically aims to illustrate the adaptability and effectiveness of these biosensing platforms in identifying precise biological targets along with their far-reaching implications across various domains, spanning healthcare diagnostics, environmental monitoring, and diverse bioanalytical fields. By exploring these applications, the article highlights the significance of prioritizing the use of natural resources for nanoparticle synthesis. This emphasis aligns with the worldwide goal of envisioning sustainable and customized biosensing solutions, emphasizing heightened sensitivity and selectivity.

Diabetes mellitus (DM) is one of the most prevalent, fatal, and non‐contagious diseases. Therefore, researchers are making attempts to develop novel anti‐diabetic drugs using various organic compounds and biomolecules. The idea of using nano‐materials as anti‐diabetic agents seems interesting. The current study aims to develop Kickxia elatine (KE) extract‐based nano‐silver (KE‐AgNPs) and to evaluate their in vivo anti‐diabetic potency in female Sprague Dawley rats. KE‐AgNPs were characterized using UV spectroscopy, X‐ray diffractometer (XRD), scanning electron microscopy (SEM), Electron Diffraction X‐ray Spectroscopy (EDX), and Fourier transforms infrared (FTIR) techniques. The crystalline nature of KE‐AgNPs with a size of 42.47 nm is confirmed by XRD screening. Spherical‐shaped mono‐dispersed KE‐AgNPs with a mean size of 50 nm are validated by SEM examination. The different phyto‐compounds (tannins, alkaloids, flavonoids, proteins, saponins, phenols, carbohydrates, quinones, sterols, fats, and oils) that contribute to the stabilization and reduction of KE‐AgNPs are confirmed by FTIR analysis. EDX showed a strong peak (3.2 keV) that identified Ag as the main component with a 61.67% contribution. The use of Alloxan to induce diabetes resulted in elevated levels of blood sugar, HbA1c, liver, and lipid profile, as well as a drastic reduction in body weight, body organ weight, and Hemoglobin. These modifications were switched following 21 days of treatment of diabetic rats, and a dosage range of 150–450 mg kg−1 BW of KE extract and KE‐AgNPs demonstrated significant inhibition as compared with the diabetic untreated group. The phytochemical analysis of the KE plant was also assessed to examine the phyto‐compounds involved in the anti‐diabetic potential of KE extract and KE‐AgNPs. These findings suggested that, in comparison with the KE extract, KE‐AgNPs have demonstrated promising anti‐diabetic action.
