Abstract: It is possible to synthesize silver nanoparticles, which are used to increase the conductivity of carbon paste electrodes used in the design of biosensors that enable the determination of the amount of H 2 O 2 in foods quickly, practically, and at low concentrations. Silver nanoparticles used in electrode modification could be obtained cheaply and eco-friendly by green synthesis technique in which bio-waste is used as electron precursor. In this study, the bio-waste leaves of pineapple ( Ananas comosus (L.) Merr.) were used in the green synthesis of silver nanoparticles (A-AgNPs). Main aim of this study is to determine the potential usage of synthesized A-AgNPs in the area of new biosensor applications. It was determined that A-AgNPs had maximum absorbance at ~ 450 nm, sized between ~ 40 and 70 nm, strong signal at 3 keV, and silver peaks representing 111°, 200°, 220°, and 311° at 2θ. The carbon paste electrode (CPE) was modified with the characterized A-AgNPs and linear detection range of H 2 O 2 was determined as 0.1–1000 µM. It was determined that silver nanoparticles obtained from waste pineapple leaves increased the surface functionality and enabled the determination of H 2 O 2 in a wider concentration range. It could be conclueded that the synthesized nanoparticles have the potential to be used in biosensor technology. Therefore, bio-wastes can be used for nanoparticle synthesis in an environmentally friendly and economically feasible way.
