“…Various chemical agents such as sodium borohydride (NaBH 4 ), sodium citrate, ascorbate, elemental hydrogen, N , N -dimethylformamide (DMF), and polyethylene glycol (PEG) block copolymers are utilized throughout the year to reduce metal ions to zero charged molecules and to form the NPs. This was accompanied by a color shift that becomes darker as the response time is increased [ 10 ]. However, the widespread use of these hazardous chemicals has recently been discussed, especially in relation to their impact on human health and safety and the environmental issues associated with their disposal [ 11 ].…”

“…One emerging concept in this field is the green chemistry of NPs, which aims to make a practical impact in industrial applications. Muthivhi et al [ 10 ] have identified three key factors to consider in the bio-based synthesis of metal NPs: (i) using a non-toxic capping agent, (ii) using an environmentally friendly reducing agent, and (iii) using an environmentally friendly solvent. To achieve this, a range of approaches to the selection of biomaterials have been explored through various studies.…”

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.

“…A number of chemicals can be used as protecting agents in the synthesis of AgNPs. However, the most commonly applied stabilizers and protective agents in nanoparticles synthesis are polymers: gelatin [14], D-sorbitol, polyvinyl pyrrolidone (PVP) [15] and PMVE (poly(methylvinylether)) [16]. Among all polymer stabilizers of silver nanoparticles, poly(N-vinylpyrrolidone) is considered an excellent dispersant as it exhibits favourable protecting properties owing to its unique structure [17,18].…”

1 The contact non-equilibrium low-temperature plasma technique is used to synthesize silver nanoparticles (AgNPs) employing polyvinyl pyrrolidone (PVP) as a capping agent. Influences of PVP concentration on the formation efficiency of silver nanoparticle, their average size and stability have been studied. The synthesized silver nanoparticles had a significant antibacterial activity against two strains of Gram bacteria. Silver nanoparticles (AgNPs)-alginate composite beads with different PVP concentration were synthesized as materials for water purification.Анотація. За допомогою контактної нерівноважної низькотемпературної плазми одержані наночастинки срібла (AgНЧ) із застосуванням полівінілпіролідону ( ПВП) як стабілізуючого агенту. Вивчено вплив концентрації ПВП на ефективність формування наночастинок срібла, їх середній розмір та стабільність. Встановлено, що одержані наночастинки срібла проявляють антибактеріальну активність проти двох штамів грам-бактерій. Одержано композитні гранули (AgНЧальгінат) з різною концентрацією ПВП для очищення води.Ключові слова: наночастинки срібла, плазма, полівінілпіролідон, композитний матеріал, антибактеріальний.

В настоящее время в качестве одного из наиболее перспективных направлений такого поиска рассматривается направление, связанное с получением композитных материалов на основе полимерной матрицы с инкорпорированными в нее ультрадисперсными частицами различных неорганических соединений [1][2][3]. Такие системы основаны на использовании преимуществ сложной каркасной молекулярной структуры полимерной матрицы и высокой химической активности наночастиц, характеризующихся высокой удельной поверхностью и, как следствие, высокой долей свободной энергии [4,5].…”
