In recent decades, nanotechnology has received great attention due to its broad fields of application. The conventional processes applied to the synthesis processes of nanomaterials can be classified in chemical and physical methods. These technologies involve several environmental and cost problems. In order to avoid the problems caused by conventional methods, the use of biological systems such as bacteria, fungi, yeasts, and algae in the synthesis of nanomaterials has recently received extensive attention. To the same purpose, the routes of synthesis of metallic and metal oxides nanoparticles using plant extracts show promising perspectives. The methods involving plant extracts, unlike other biological methods, stand out for their ease and low implementation costs. In addition, the use of plant extracts avoids the risks associated with the use of highly toxic compounds, which are harmful to human health and the environment. This review summarizes the relevance of using plant extracts in the synthesis of metal and metal oxides nanoparticles compared to other synthesis methods and emphasizes the use of extracts of different species of Eucalyptus. The main topics covered by this review include (i) the effect of the synthesis parameters on the features of the nanomaterials; (ii) the effect of the composition of the extracts on the synthesis; (iii) the main mechanisms proposed to explain the formation of the nanoparticles; and (iv) future challenges related to the green synthesis of nanoparticles.

“…Monometallic nanoparticles as well as metallic alloy nanoparticles have been manufactured using plant-based approaches. For instance, Ag–Ni, Ag–Co, Pt–Cu, Au–Ag, Ag–Cu, and Zn–Ag nanoparticles have been produced using the leaf extracts of Canna indica , Alchornealaxiflora , Azadirachta indica, Cacumen Platycladi , palm, Mirabilis jalapa, and Moringa oleifera [ 179 , 180 , 181 , 182 , 183 , 184 , 185 ], Au–Ag–Sr, and Fe–Ag–Pt nanoparticles were produced from the roots of coriander, Platycodon grandiflorum [ 13 , 186 ], and Au-Ag nanoparticles have been produced from the Chinese wolfberry fruit extracts [ 187 ].…”

Metallic alloy nanoparticles are synthesized by combining two or more different metals. Bimetallic or trimetallic nanoparticles are considered more effective than monometallic nanoparticles because of their synergistic characteristics. In this review, we outline the structure, synthesis method, properties, and biological applications of metallic alloy nanoparticles based on their plasmonic, catalytic, and magnetic characteristics.

“…The authors revealed only the catalytic properties of the generated NPs and demonstrated the effectiveness of 2,4,6-trinitrophenols for the catalytic destruction. The authors of [9] obtained the bimetallic alloy Ag-Au with the use of fruit extract (Goji berries). The extract was obtained by maceration during boiling.…”

“…However, there is no data on the properties of the obtained materials and an industry for their further practical application. It should also be noted that the authors of other studies [8][9][10] consider only traditional methods, particularly maceration method, for obtaining extracts of the plant material. The main disadvantage of the method is incompleteness of the extraction.…”

Здiйснено "зелений" синтез монометалiчних (Au, Ag) та бiметалiчних (Au-Ag) наночастинок (НЧ) з водних розчинiв iонiв металiв вiдповiдних прекурсорiв iз використанням вiдходiв агропромислового виробництва (шкiрки винограду). Наразi гостро стоїть проблема утилiзацiї вiдходiв агропромислового комплексу, рацiонального природокористування та перехiд до використання екологiчно безпечних енергоефективних технологiй. Тому спостерiгається тенденцiя використання "зелених" технологiй при одержаннi наноматерiалiв, що вважаються екологiчно безпечними та ресурсозберiгаючими. Встановлено ефективнiсть використання харчових вiдходiв (шкiра винограду), як вiдновника та стабiлiзуючого агента для формування наночастинок дорогоцiнних металiв моно-та бiметалевої структури. Екстракцiю бiологiчної сировини проводили у водному середовищi пiд дiєю короткотривалого впливу розряду низькотемпературної плазми. На основi комплексного аналiзу компонентного складу екстракту встановлено, що гiдроксильнi, карбонiльнi та карбоксильнi функцiональнi групи органiчних сполук екстракту шкiрки винограду, вiдповiдають за вiдновлення iонiв металiв та стабiлiзацiю отриманих НЧ. Встановлено, що формування моно-та бiметалiчних НЧ характеризується присутнiстю пiка для Ag 0 (λ мак =440 нм), для Au 0 (λ мак =540 нм), Ag-Au (λ мак =510 нм). Розмiр та стабiльнiсть наночастинок одержаних "зеленим" синтезом оцiнено в порiвняннi з показниками при плазмохiмiчному способi формування наночасток. Встановлено антибактерiальнi, каталiтичнi та протикорозiйнi властивостi синтезованих наночастинок. Одержанi монометалiчнi (Au, Ag,) та бiметалiчнi (Au-Ag) наночастинок показали вiдмiнну каталiтичну активнiсть для вiдновлення p-нiтрофенолу (4-НФ) до p-амiнофенолу (4-AФ) у присутностi NaBH 4. Синтезованi НЧ продемонстрували антибактерiальну активнiсть проти грампозитивних та грамнегативних бактерiй. Отриманi результати дають змогу розширити практичне застосування наночастинок металiв в рiзних галузях виробництв та вирiшити питання щодо збiльшення переробки та повторного використанню нелiквiдних вiдходiв Ключовi слова: водний екстракт, компонентний склад, виноград, вiдновлення, нiтрофенол, антибактерiальнi властивостi, антиоксидантна активнiсть
