In this study, we present a novel and sustainable approach for the synthesis of silver nanoparticles (AgNPs) using waste materials, dried banana pith extract (BPE) and rice water. The synthesised AgNPs exhibit a size of 43 nm and zeta potential of −24.1 mV. A maximum temperature rise of 4°C with an efficiency of 41% is achieved within a short time by the photothermal activity. The qualitative colorimetric detection of Fe3+ and its quantitative spectroscopic detection are achieved in a linear detection range of 20–80 μM and with a limit of detection of 8.5 μM. The sensing mechanism is explained in terms of cooperative binding of Fe3+ ions to BPE-AgNPs. A homogeneous, flexible and stable AgNP-rice starch gel is formed.

Graphene quantum dots have been found as remarkable zero-dimensional derivative of graphene having size of up to 20 nm. Similar to graphene, graphene quantum dots have been applied as beneficial nano-reinforcement for the polymers. In this context, various conductive polymers (polypyrrole, polyaniline, polythiophene, etc.) and thermoplastic polymers (poly(vinyl alcohol), poly(vinyl fluoride), etc.) have been used as matrices. Inclusion of graphene quantum dots in matrices have revealed superior structure, morphological, electronic, optical, photoluminescence, and several other advantageous physical characteristics. Important application areas of polymer/graphene quantum dots nanomaterials have been observed for solar cells, sensors, supercapacitors, batteries, memory devices, and bioimaging. However, further research efforts have been desirable regarding the graphene quantum dots modification and exploration of new graphene quantum dots derived nanocomposite designs and applied sectors as well as overcoming the related challenges for future progressions in this important category of nanocomposites.KEYWORDS: Graphene quantum dotsconductive polymernanocompositessensorsolar cell Disclosure statementNo potential conflict of interest was reported by the authors.","PeriodicalId":18235,"journal":{"name":"Materials Research Innovations","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135994263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
