This study reports a scalable green electrochemical synthesis of novel biogenic silver nanoparticles colloid (biogenic AgNPs) in large scale up to 5 liters using the bulk silver bar and the green tea leaves (Camellia sinensis) extract (GTE) as reducing ag |
An electrochemical approach has been used for green synthesis of gold and silver nanoparticles (e-AuNPs and e-AgNPs) with high levels of purity and scalability. The electrochemically synthesized noble-metal nanoparticles were characterized by ultraviolet–visible (UV–Vis) spectroscopy and scanning electron microscopy (SEM), confirming the formation of spherical e-AuNPs and e-AgNPs with average size of 19 nm and 24 nm, respectively. These green nanoparticles were deposited on aluminum substrates using the drop-drying method for surface-enhanced Raman scattering (SERS)-based detection of Methylene Blue (MB) within the ranges from 10−5 M to 10−8 M and 10−7 M to 10−10 M, respectively. The SERS sensors also exhibited outstanding sensing performance for MB detection with limits of detectio... |
An efficient colorimetric probe based on surface-functionalized silver nanoparticles (AgNPs) was prepared for sensitive thiram pesticide detection in water samples. The influence of various surface capping agents including polyhexamethylene biguanide hydr |
Functional two-dimensional (2D) structured nanomaterials, such as, graphene oxide (GO) and molybdenum disulfide (MoS2), exhibit many advantages, including large surface areas and excellent electronic/mechanical/catalytic properties, and have shown to be s |
