Description: Innovations with sustainable outcomes that creates little or no hazards to the ecosystem and globe has recently emerged as a pressing concern in Nanotechnology and Agriculture, hence promoting reduction in carbon emission. A novel and analytical research study on the biological synthesis of silver nanoparticles (AgNPs) coupled with the formulation of nano-encapsulated fertilizer, and the use of chitosan matrix to obtain a highly sustainable delivery to crops was the main aim of this study. The objectives include the synthesis of AgNPs, characterization, nano-encapsulation, nano-delivery and the analysis of bioactive activities of AgNPs. The biological synthesis of AgNPs was carried out using ?-1, 3 glucan binding protein isolated and purified from a Portunus pelagicus commonly known as swimmer crab. The synthesized AgNPs were further characterized using a UV-Vis Spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) for analysis of the morphology of AgNPs, and Fourier transform infrared spectroscopy (FTIR). The best UV-Vis spectra result had an absorbance of 410nm. SEM was measured at 1?m, 2?m, and 5?m, and FTIR showing a record of 3440, 2870, 1650, 1425 and 1100 cm-1. AgNPs were loaded to the chitosan matrix. Chitosan nanoparticles fused with phosphorus compound reported a mean size of 440 ? 10nm, zeta potential of -28 ? 0.5mV, polydispersity index of 0.2 and a concentration of 1.54 x 1011 mL-1. It was observed from the research study that AgNPs where stable for 50 days of controllable release on Spinacia oleracea. The bioactivity results revealed this innovative strategy to be of high efficiency.
