Abstract Scope |
The synthesis in situ of metal nanoparticles and biopolymer composites by electrochemical technique as potential immobilization surfaces for biosensors are narrowly investigated. Polymerization can be obtained by applying a specific potential making a more rapid, eco-friendly, and cost-effective process, such as metal reduction to nanoparticles. Gold nanoparticles (AuNP) are widely used in the biomedical field, such as different biopolymers, especially in the immobilization of biomolecules for biosensors. As a functionalization of AuNPs, biopolymers offer functional groups to the surface of the nanoparticles to enhance molecule binding. One of the most generous biopolymers is chitosan (Ch), which stands out for its amine and hydroxyl groups used to bind biomolecules, high solubility, mechanical strength, and non-toxic film formation. Among other natural polymers, polygalacturonic acid (PGA) has been used in a wide range of biomedical applications because of its low toxicity and good biocompatible response towards the human body. Also, PGA has been used as a reducing and stabilizer agent for synthesizing metal nanoparticles owing to its carboxyl and hydroxyl functional groups which can be used as a scaffold, aiming for an efficient composite. In this study, we synthesize and analyze the interaction of a biopolymer and metal nanoparticles as nanocomposites, AuNP-Chitosan and AuNP-PGA, by electrochemical techniques. |
