Green Synthesis or Green Chemistry of silver nanoparticles (AgNPs) has many advantages, one of which is fast, easy, and cheap. AgNPs have many benefits in the health sector. AgNPs are of great interest in the field of nanoparticle development because they have good biomedical and anti-bacterial activities. Bioreductors play an important role in reducing the size of AgNPs, in this study a natural bioreductor in the form of Kiwi extract (Actinida deliciosa) was used. Purpose of the study the objective of this research was the biosynthesis of AgNPs using a kiwifruit extract bioreductor. Research methods with extraction of Kiwi, synthesis of AgNPs using Kiwi extract, characterization of AgNPs formed using UV-Visible spectroscopy (UV-Vis), Fourier-transform Infrared Spectroscopy (FTIR), and Particle Size Analyzer (PSA). Research Results that AgNP formation was confirmed by optical performance using UV-VIS spectroscopy and showed an AgNP peak at 415 nm. The C-H, C-N, and C=O groups in Actinidia deliciosa were confirmed by FTIR.

“…In the past two decades, the development of electrochemical voltammetric techniques and the fabrication of low-cost modified electrodes for sensitive and selective DA estimation in body fluids has gained attention; ascorbic acid (AA) and uric acid (UA) interference-free detection of DA has been an especially challenging task [ 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Various chemically modified electrodes have been constructed based on organic redox mediators [ 28 ], polymers-modified electrodes [ 29 , 30 ], metal nanocomposites [ 31 , 32 , 33 ] and nanoparticle-modified electrodes [ 34 ]. This work covers detailed literature information about the nature of PGE and its activation techniques adopted in the literature for the DA electroanalysis.…”

Pencil graphite electrode (PGE) is an alternative, commercially available, ready-to-use, screen-printed electrode for a wide range of electroanalytical applications. Due to the complex-matrix composition and unpredictable electro-inactive nature of PGE in its native form, a surface pre-treatment/activation procedure is highly preferred for using it as an electroactive working electrode for electroanalytical applications. In this article, we review various surface pre-treatment and modification procedures adopted in the literature with respect to the sensitive and selective detection of dopamine as a model system. Specific generation of the carbon–oxygen functional group, along with partial surface exfoliation of PGE, has been referred to as a key step for the activation. Based on the Scopus® index, the literature collection was searched with the keywords “pencil and dopamine”. The obtained data were segregated into three main headings as: (i) electrochemically pre-treated PGE; (ii) polymer-modified PGEs; and (iii) metal and metal nanocomposite-modified PGE. This critical review covers various surface activation procedures adopted for the activation for PGE suitable for dopamine electroanalytical application.

“…On the other hand, if the use of nanometric carbonaceous materials amplifies the electroanalytical response of a given detection study, the formation of a nanocomposite with these microstructures favorably increases the current response in micro-analytical analyses. For example, nanoparticles of noble materials (gold, platinum, and silver) are of great prominence in the field of electroanalysis focused on environmental analysis [ 18 , 19 , 20 ], as gold nanospheres have a diameter between 1 and 100 nm that contributes to high surface energy and their surface ratio–volume favors the immobilization of a large number of molecules that suppress their catalytic activity [ 21 ]. Finally, when this class of materials is used for the oxidation of electroactive species in a sensing application, they provide a direct and rapid electron transfer between a variety of species capable of oxidation or reduction reactions [ 18 , 22 ].…”

Nifedipine, a widely utilized medication, plays a crucial role in managing blood pressure in humans. Due to its global prevalence and extensive usage, close monitoring is necessary to address this widespread concern effectively. Therefore, the development of an electrochemical sensor based on a glassy carbon electrode modified with carbon nanofibers and gold nanoparticles in a Nafion® film was performed, resulting in an active electrode surface for oxidation of the nifedipine molecule. This was applied, together with a voltammetric methodology, for the analysis of nifedipine in biological and environmental samples, presenting a linear concentration range from 0.020 to 2.5 × 10−6 µmol L−1 with a limit of detection 2.8 nmol L−1. In addition, it presented a good recovery analysis in the complexity of the samples, a low deviation in the presence of interfering potentials, and good repeatability between measurements.
