“…Rhamnolipid, primarily a crystalline acid, is composed of β-hydroxy fatty acid connected by the carboxyl end to a rhamnose sugar molecule. Rhamnolipids are predominantly produced by Pseudomonas aeruginosa and classified as: mono and di-rhamnolipids [6]. The most crucial function of these Rhamnolipids is their capacity to bind insoluble metal ions, oxides, and hydroxides and release them gradually and constantly to plants as required.…”

Rhamnolipids has been used as capping agent for ZnO nanoparticles to improving the plant micronutrition. ZnO nanoparticles were synthesized using co-precipitation method, and the prepared nanoparticles were capped with Rhamnolipids. The structural, morphological, optical, and particle stability characteristics of the chelated ZnO nanoparticles were investigated. UV - vis spectroscopy was used to investigate the optical properties of ZnO and Rhamnolipids capped ZnO nanoparticles. The stability of Rhamnolipids capped ZnO nanoparticles is higher (38.45 mV) than that of ZnO nanoparticles alone (32.3mV). The Zn mineral nutrition in plants is improved by Rhamnolipids capped ZnO nanoparticles. In order to get a broad understanding of the binding of capped ZnO nanoparticles, a detailed molecular docking analysis was taken up. Molecular docking analysis reveals that the binding of Zn atom to LasI protein receptor has more neighboring group amino acid residues and greater binding affinity than the binding to LasR receptor.

“…Therefore, in this study, the sol–gel method was preferred to obtain the seed layers. The main reactions of the sol–gel method can be summarized as follows (Singh & Nanda, 2015):

{Zn}^{+ 2} + 4 {OH}^{-} ⇌ {([], Zn {(OH)}_{4})}^{2 -},

{([], Zn {(OH)}_{4})}^{2 -} ⇌ Zn {O_{2}}^{2 -} + 2 {normalH}_{2} O,

Zn {O_{2}}^{2 -} + 2 {normalH}_{2} O ⇌ ZnO + 2 O {normalH}^{-} .

In this study, ZnO seed layers with different cycles were formed on glass substrates by the sol–gel technique, and ZnO nanorods were grown on them by the hydrothermal method. Morphology and the structural characterization of the seed films and the ZnO nanorods are carried out by field emission scanning electron microscopy (FE‐SEM) and x‐ray diffraction techniques. In addition, to investigate the effect of seed layer deposition cycles on the optical properties of the ZnO nanorod arrays, UV/visible spectrophotometer and photoluminescence (PL) measurements were performed. The changes in structural and optical parameters such as dislocation density, strain, crystallite size, and optical band gap values on each seed layer deposition cycle were examined. The highest optical band gap and crystallite size were obtained for ZnO nanorods with 4 cycles seed layer as 3.22 eV and 63.6 nm, respectively. Also, in the PL spectrum, the largest ratio of UV‐emission region to weak‐visible emission region was obtained in ZnO nanorods having 4 cycles. In addition, the glucose detection properties of ZnO nanorods having 4 cycles were investigated using the PL measurements and it was found that UV‐emission peak intensity of ZnO nanorods decreased as the glucose concentration increased from 8 to 40 mM. The results show that the number of deposition cycles of the seed layer has a strong influence on the orientation, crystal quality, and optical band gap of the growing ZnO nanorods, as well as significantly affecting their morphological properties.Research Highlights High quality ZnO nanorods were grown on glass substrates by hydrothermal method. The effect of ZnO seed layer cycles on the structural, optical, and morphological characteristics of ZnO nanorods grown on were examined. It was found that the number of cycles of the seed layer is a critical parameter for growing quality and well‐aligned ZnO nanorods.
