“…Recently, the concept of honey-mediated green synthesis has gained traction as a method of synthesizing gold NPs (Au-NPs) [ 40 , 41 ], Ag-NPs [ 36 , 42 , 43 ], carbon NPs [ 44 ], platinum NPs (Pt-NPs) [ 45 ], and palladium NPs (Pd-NPs) [ 46 ]. Typically, honey functions as both a reducing agent and a capping/stabilizing agent in the NP synthesis process, primarily serving as a precursor [ 47 ]. The preparation of NPs using honey follows a general mechanism that involves the following steps [ 48 ]: Initially, the metal salt solution undergoes dissociation to produce positively charged metal ions (Me n+ ).…”

The use of natural reducing and capping agents has gained importance as a way to synthesize nanoparticles (NPs) in an environmentally sustainable manner. Increasing numbers of studies have been published on the green synthesis of NPs using natural sources such as bacteria, fungi, and plants. In recent years, the use of honey in the synthesis of metal and metal oxide NPs has become a new and promising area of research. Honey acts as both a stabilizing and reducing agent in the NP synthesis process and serves as a precursor. This review focuses on the use of honey in the synthesis of silver NPs (Ag-NPs) and zinc oxide NPs (ZnO-NPs), emphasizing its role as a reducing and capping agent. Additionally, a comprehensive examination of the bio-based reducing and capping/stabilizing agents used in the honey-mediated biosynthesis mechanism is provided. Finally, the review looks forward to environmentally friendly methods for NP synthesis.

“…Alkaline pH honey can convert silver ions into Ag NPs [22]. Chromium oxide nanoparticles can be rapidly synthesized by the reduction of potassium dichromate solution using natural honey [23]. Similarly, CoFe 2 O 4 , ZnFe 2 O 4 , NiFe 2 O 4 and Ag/CoFe 2 O 4 have been synthesized using natural honey as an oxidizing precursor [23][24][25][26].…”

Iron oxide nanoparticles are produced using simple auto combustion methods with honey as a metal-stabilizing and -reducing agent. Herein, α-Fe2O3 nanoparticles are produced using an iron nitrate precursor. These prepared samples are analyzed by an X-ray diffractometer (XRD), FTIR spectroscopy, UV-DRS, and a field-emission scanning electron microscope (FESEM) combined with energy-dispersive spectroscopy and a vibrating sample magnetometer (VSM). The XRD results confirm a rhombohedral structure with an R3c¯ space group single-phase formation of α-Fe2O3 in all samples. FESEM images reveal the different morphologies for the entire three samples. TEM analysis exhibits spherical shapes and their distribution on the surfaces. XPS spectroscopy confirms the Fe-2p and O-1s state and their valency. The VSM study shows strong ferromagnetic behavior. The prepared α-Fe2O3 nanoparticles exhibit exceptional charge carriers and radical production. The prepared sample retains excellent photocatalytic, antifungal and antibacterial activity.

“…We also investigated the effect of Cr 2 O 3 -NPs on K. pneumoniae persister cells as an antibacterial and antibiofilm formation agent. According to several reports [28,29], Cr 2 O 3 -NPs improved the antimicrobial activity toward a wide range of microbial pathogens. In the current study, we found that the Cr 2 O 3 -NPs treatments would be one of the most effective antibacterial agents (p < 0.05) as the inhibition zones were 18 and 12 mm in values of 10.000 and 1000 μg/mL, respectively to eradicate K. pneumoniae persister cells.…”

Bacterial persistence is recognized as a major cause of antibiotic therapy failure, causing biofilms and chronic intractable infections. The emergence of persisters in K. pneumoniae isolates has become a worldwide public health concern. Despite this clinical threat, currently, there are no viable means for eradicating K. pneumoniae persisters. In this project, chromium oxide (Cr 2 O 3 ) nanoparticles were synthesized by the photochemical method. The morphology, topographic and physical properties of nanosynthesized were described by transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray powder diffraction (XRD), and ultraviolet-visible spectroscopy (UV. vis) measurements. The obtained average size of Cr 2 O 3 -NPs was to be ranging from 11 to 30 nm. The activities of the Cr 2 O 3 -NPs for antibacterial and antibiofilm formation against persistent K. pneumoniae were assessed. The result showed a significant inhibitory effect of Cr 2 O 3 -NPs against K. pneumoniae. A, where the zones of inhibition were 12-18 mm, and the minimum inhibitory concentration (MIC) was 625 μg/mL. The concentration of Cr 2 O 3 -NPs of 10 mg/mL demonstrated the highest inhibition activity against biofilm formation (73.95 ± 2.17%), indicating the lowest inhibition (19.08 ± 1.32%) at a level of 0.625 mg/mL. Cr 2 O 3 -NPs therefore had a positive impact on biofilms that were produced by persistence isolates of K. pneumoniae.
