Characterization of Calcium Phosphate Chitosan Nanocomposite as Plant Growth Promoter

Abstract

In this study, calcium phosphate-chitosan nanocomposite (CaP-CS NC) was prepared by a convenient and affordable co-precipitation method, and the prepared NC was tested for agriculture application. Physico-chemicals analyses of the CaP-CS NC were conducted by X-ray diffraction (XRD), scanning electron microscope with energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-Vis) instruments to determine the structural characteristics, surface topology, chemical composition, function group, and optical properties. The XRD pattern of CaP-CS NC revealed that the average crystallite size was 43 nm. The SEM images showed agglomeration of the CaP-CS NC with a rod-like shape. The EDS spectrum of the CaP-CS NC indicated the presence of Ca, P, O, and N elements. FTIR displayed vibrational peaks for the active functional group such as carboxylic (C=O), amines (N-H), hydroxyl (O-H), and alkyne (C-H). Furthermore, the spectrum of CaP-CS NC showed the bending mode of phosphates at 588.37 cm-1 and 508.45 cm-1. The UV-Vis-NIR spectrum of the prepared nanocomposite indicates the anti-reflection properties, which might be useful in solar cell applications to increase the efficiency of the solar cell. In addition, the prepared CaP-CS NC was tested for the plant growth stimulator properties at the lab scale level, wherein it exhibited substantial growth. Accordingly, the current study suggests that the prepared CaP-CS NC could be used as a plant growth promoter.

Calcium Orthophosphate (CaPO4) Containing Composites for Biomedical Applications: Formulations, Properties, and Applications

“…Non-biomedical applications of CaPO 4 -based composites and hybrid formulations are also known, and their amount rapidly increases [460,461,[834][835][836]874,980,1089,1090,[1271][1272][1273][1274][1275][1276][1277][1278][1279][1280][1281][1282][1283][1284][1285]. For example, battery devices employ DCPD/polymer composites as proton conductors [460,461], an HA-contained porous gel polymer electrolyte was developed for a quasi-solid-state sodium ion battery [1280], and HA/carbon nanotube was found to be an anode modifying material [1284], while CuO/HA composites appeared to be excellent dielectric materials [1283].…”

“…Furthermore, PEG/HA composites appeared to be a suitable phase change material, which was useful for thermal energy storage [1275], while a full-daytime subambient cooling TCP/acrylic paint was found to be effective for energy saving [1281]. In addition, CaPO 4 /chitosan composites could be used as a plant growth promoter [1282], while HA/gelatin ones appeared to resemble a synthetic ivory suitable to produce piano keys [1279]. Finally, there are different fields of application for bone char, starting from environmental remediation to sustainable agriculture and catalysis [1089,1090].…”

Mitigating Global Challenges: Harnessing Green Synthesized Nanomaterials for Sustainable Crop Production Systems

“…[5][6][7][8][9][10] The recent focus of nanotechnology has been on the detection and control of plant diseases as well as the creation of nanonutrients to promote plant growth. [11][12][13][14] A technique to transport various macro-and micronutrients into the soil gradually and in a controlled way, preventing accumulation and polluting of diverse natural resources, is to replace traditional techniques of fertilizer delivery with nanofertilizers. Nanofertilizer innovation necessitates a multidisciplinary approach because it has the ability to outperform conventional fertilizers.…”
