“…It has been reported that nanoparticles with novel shapes exhibit optical, electrical, and catalytic properties that are distinct from those of conventional spherical shapes, as well as wider biological and medical applications [ 28 ]. In this regard, numerous studies have focused on creating intricate Ag nanostructures [ 16 , 29 , 30 , 31 , 32 ]. Among them, flower-like AgNPs, also known as Ag nanoflowers, are particularly appealing, as their novel and collective physicochemical properties, which are not visible at the level of individual particles, can be manifested from their anisotropic structure [ 16 ].…”

Herein, we report the green synthesis of flower-like carrageenan-silver nanoparticles (c-AgNPs) through a facile hydrothermal reaction at 90 °C for 2 h. The reduction of silver nitrate (AgNO3) to c-AgNPs was evident by the colour change of the solution from colourless to dark brown and further confirmed by a UV-Vis surface plasmon resonance (SPR) peak at ~420 nm. The FTIR spectra showed that the abundance of functional groups present in the carrageenan were responsible for the reduction and stabilisation of the c-AgNPs. The XRD pattern confirmed the crystalline nature and face-centred cubic structure of the c-AgNPs, while the EDX analysis showed the presence of a high composition of elemental silver (85.87 wt%). Interestingly, the morphological characterisations by SEM and FE-SEM revealed the formation of flower-like c-AgNPs composed of intercrossed and random lamellar petals of approximately 50 nm in thickness. The growth mechanism of flower-like c-AgNPs were elucidated based on the TEM and AFM analyses. The c-AgNPs displayed promising antibacterial properties against E. coli and S. aureus, with zones of inhibition ranging from 8.0 ± 0.0 to 11.7 ± 0.6 mm and 7.3 ± 0.6 to 9.7 ± 0.6 mm, respectively, as the concentration of c-AgNPs increased from 0.1 to 4 mg/mL.

“…Various parts of plant like seed, stem, leaf and flower are extensively used for production of AgNPs. For example, Wang et al [51] have synthesized silver nanoflowers by using leaf extracts. Jayaprakash et al [6] have produced AgNPs by using the extract of Piper nigrum (black pepper) as a reducing as well as capping agent in aqueous medium without addition of any other chemicals.…”

In last few decades, synthesis of metal nanoparticles such as silver, gold, copper, platinum and iron has been spotlighted with much interest among the material scientists due to their peculiar properties such as tunable optical property, electrical property, good chemical reactivity, thermal stability, large surface areas to volume ratio, magnetic property, high catalytic activity and easy handling [1,2]. They have been used in diverse fields such as cosmetics, medical diagnosis, therapy, energy, electronic devices, catalysis, sensors and waste treatment process [3-6]. Among the metal nanoparticles, silver nanoparticles (AgNPs) have much interest due to their exclusive physical, chemical and biological properties compared to bulk material. It has been used in inks [7

“…Because, AgNPs harm the cell membrane and the cellular content of the organism by inhibiting cell division (Sana et al, 2018;Paosen et al, 2017). Several methods for the synthesis of AgNPs have been reported which includes thermal decomposition (da Silva Pereira et al, 2015), wet chemical reduction (Wang et al, 2018), electrochemical (Abudabbus et al, 2018), microwave (Yüksel et al, 2016) ball milling method (Salarian et al, 2017) and laser ablation method (Arakcheev et al, 2018;Sportelli et al, 2019). The disadvantages of these methods are expensive, high temperature and pressure requirements, and the formation of toxic by-products including carcinogenic and/or highly active radicals resulting from the use of harmful solvents (sodium borohydride, hydrazine, ethylenediamine tetraacetic acid and N, N-dimethyl formamide etc.)…”

This paper describes the simple and environmentally friendly production of AgNPs using Dimrit raisin, grown in Burdur, extract. To optimize the synthesis of AgNPs, a number of variables, including extract concentration, silver solution concentration, synthesis time, and synthesis temperature, were investigated. AgNPs were obtained after 173 h at 1% extract concentration and 10-1 M silver concentration. The structure of the synthesised AgNPs was investigated by Transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-visible spectroscopy, and Fourier transform infrared spectroscopy (FT-IR). TEM analysis showed that the majority of the AgNPs had a spherical shape, and the average particle size was 30 nm. Antimicrobial activity was seen against Staphylococcus aureus ATTC43300, Enterococcus faecalis ATTC29212, Bacillus subtilis, Listeria monocytogenes, Klebsiella pneumoniae and Gram-negative Salmonella enterocolitis, E. coli 0157:H7 ATTC 43895, and Escherichia coli ATTC 35150.
