Fine Ultrasmall Copper Nanoparticle (UCuNPs) Synthesis by Using Terminalia bellirica Fruit Extract and Its Antimicrobial Activity

Abstract

In this present manuscript, ultrasmall copper nanoparticles (UCuNPs) was synthesized by Terminalia bellirica fruit extract as a reducing agent. The method of synthesis is ecofriendly, single step, aqueous and ambient method. As synthesized nanoparticles were in diameter of 2-7 nm. The surface plasmone resonance is observed with UV-visible spectrophotometry, UCuNPs are nonplasmonic. Fourier transform infrared spectroscopy indicates that oxygen-containing functional groups in the T. bellirica fruit extract are involved in the nanoparticle synthesis reaction. High-resolution transmission electron microscopy (HRTEM) was used to confirm that the UCuNPs are spherical shape. XRD analysis confirms that the nanoparticles are single crystalline. X-ray energy dispersive spectroscopy conducted during HRTEM analysis confirms the presence of pure copper in the sample. The particle size analysis is also confirms that the particles were polydispersed. The stability of UCuNPs characterized by zeta potential. We are also done antimicrobial activity (anti bacterial and anti fungal) of UCuNPs shown good activity.

Andean Sacha Inchi (Plukenetia Volubilis L.) Leaf-Mediated Synthesis of Cu2O Nanoparticles: A Low-Cost Approach

“…The average width of the Cu 2 O nanoparticles was found to be 8.2 ± 2.1 nm with polydispersity index (PDI) = 0.0656. The observed PDI < 0.1 clearly indicates that the synthesized Cu 2 O nanoparticles were monodispersed in nature [ 29 ]. However, the average size of as-synthesized Cu 2 O nanoparticles determined by the DLS method was slightly higher than in the TEM analysis.…”

“…Therefore, they are favored over chemical and physical synthesis methods [ 21 ]. Previously reported syntheses of cuprous oxide/cupric oxide (Cu 2 O/CuO) nanoparticles have used plant materials to support large-scale synthesis, including extracts of Azadirachta indica leaf [ 22 ], Aegle Marmelo leaf [ 23 ], Aloe barbadensis Miller leaf [ 24 ], Acalypha indica leaf [ 25 ] Punica granatum peel [ 26 ], Terminalia arjuna bark [ 27 ], Stachys lavandulifolia flower [ 28 ], Terminalia bellirica [ 29 ] and Rubus glaucus fruit [ 30 ], etc.…”

Plant Mediated Green Synthesis of CuO Nanoparticles: Comparison of Toxicity of Engineered and Plant Mediated CuO Nanoparticles towards Daphnia magna

“…Plants and their related materials for production of nanomaterials are not only ecofriendly alternatives, but they are also cost effective. Synthesis of copper oxide (CuO) nanoparticles has been performed using extracts of soybeans [8], gum karaya [9], bark extract [10], leaf extract [11,12], fruit [13,14], tea and coffee powder [15], peel extract [16] and flower extract [17]. …”

Toksisitas Nanopartikel Terhadap Biota Dan Lingkungan Laut

“…Tanaman dan bahan terkait untuk produksi nanomaterial tidak hanya alternatif ramah lingkungan, tetapi juga hemat biaya. Beberapa ekstrak bahan alam yang telah digunakan untuk sintesis nanopartikel, yakni ekstrak kedelai (Guajardo et al, 2010), getah karaya (Thekkae Padil, & Černík, 2013), ekstrak kulit kayu (Yallappa et al, 2013), ekstrak daun (Naika et al, 2015), buah (Viswadevarayalu et al, 2016), teh dan kopi bubuk (Sutradhar et al, 2014), ekstrak kulit (Tamuly et al, 2014) dan ekstrak bunga (Karimi & Mohsenzadeh, 2015), akar gingseng merah Korea (Leonard et al, 2011). Namun, evaluasi sintesis hijau NP belum banyak dilakukan, sehingga dalam kajian ini membahas karakteristik dari sintesis hijau NP dengan tingkat bahaya yang ditimbulkan.…”
