“…Diantara beragam nanopartikel, material magnetik spinel ferit telah menarik perhatian para peneliti selama beberapa tahun belakangan ini karena sifat magnetik, listrik, dan optiknya yang unik (Kurian dan Jacob Mathew 2017) serta memiliki aplikasi dalam berbagai bidang. Spinel ferit memiliki rumus umum MFe 2 O 4 (M= Cu, Mn, Mg, Zn, Ni, dan lain-lain) (Nishida et al 2016). Nanopartikel Tembaga Ferit (NTF) merupakan salah satu jenis spinel ferit yang penting (Ghaani dan Saffari 2016).…”

PENDEKATAN GREEN SYNTHESIS NANOPARTIKEL CuFe2O4 DENGAN BANTUAN EKSTRAK DAUN GAMBIR DAN SIFAT ANTI BAKTERINYA. Perkembangan nanoteknologi berkaitan dengan nanomaterial berfungsi untuk meningkatkan aktivitas antibakteri serta mengurangi pemakaian logam. Penelitian ini bertujuan untuk mengetahui pengaruh suhu, pH, dan waktu reaksi terhadap sifat nanopartikel tembaga ferit (CuFe2O4), yang selanjutnya diaplikasikan sebagai agen antibakteri. Nanopartikel Tembaga Ferit (NTF) disintesis dengan memadukan metode green sintesis dan hidrotermal menggunakanekstrak daun gambir (Uncaria gambir Roxb.) sebagai capping agent. Hasil analisis X-Ray Diffraction (XRD) memberikan informasi bahwa NTF yang disintesis dengan penambahan ekstrak daun gambir dan NaOH serta dengan penambahan NaOH saja pada pH 12 dan suhu 180°C selama 8 jam menghasilkan NTF dengan struktur kubik berpusat muka dengan grup ruang Fd3mZ sesuai dengan standar ICSD #153013. NTF yang disintesis dengan penambahan ekstrak daun gambir dan NaOH pada pH 12 suhu 180°C selama 8 jam memiliki ukuran paling kecil yaitu 24 nm. Berdasarkan hasil Scanning Electron Microscope (SEM), NTF yang disintesis dengan ekstrak daun gambir dan NaOH, serta NaOH saja pada suhu 180 °C selama 8 jam pada pH 12 berbentuk bulat dengan distribusi yang merata meskipun masih ada yang teraglomerasi. Nanopartikel tembaga ferit yang disintesis diaplikasikan pada bakteri gram positif (Staphilococcus aureus) dan gram negatif (Escherichia coli) menggunakan metode difusi sumuran. NTF yang disintesis pada suhu 180°C selama 8 jam pH 10 dan pH 12 efektif menghambat pertumbuhan bakteri E. coli dan S. aureus.

“…Up to now, several types of δ-FeOOH nanostructures have been successfully synthesized using different methods. These include nanosheets obtained through a chemical transformation process by oxidizing ultrathin Fe(OH) 2 nanosheets [41], nano-disks produced via γ-irradiation of iron(III) aqueous colloidal solutions [42], nano-particles synthesized through precipitation of Fe 2+ solutions with sodium hydroxide [27], spherical nano-particles obtained by hydrazine reduction [43], nanoparticles produced by rapid oxidation of iron(II) hydroxide using hydrogen peroxide (H 2 O 2 ) [17]. In addition to these methods, δ-FeOOH nanoparticles have also been synthesized through precipitating Fe(OH) 2 followed by fast oxidation with H 2 O 2 [21,44,45], and through traditional methods [46,47].…”

Feroxyhite (δ-FeOOH) nanomaterials were successfully synthesized through the atmospheric AC microplasma method at room temperature from ferrous sulfate aqueous solutions. Various syntheses conditions, including electric voltage, electric ﬁeld strength, ferrous concentration, H2O2 concentration, and reaction duration, were systematically investigated. The synthesized products were characterized through X-ray diﬀraction, UV-vis absorption spectroscopy, photoluminescence spectroscopy, infra-red spectroscopy, and electron microscopy. The bandgap of the produced materials were strongly dependent of the ferrous concentration while the product ratio was dependent on all experimental conditions. The synthesis mechanism was thoroughly discussed. The synthesized nanomaterials were amorphous nanospheres,

Most hydrogels are prepared with using synthetic polymers that are nonecofriendly materials. Also, hydrogel nanocomposites are mostly prepared in the multi-step processing through costly techniques. Here, starch as a natural, biodegradable, hydrophilic, and inexpensive material was used for fabrication of a copper ferrite starch nanocomposites hydrogel. This was synthesized using alkali starch solution along with copper and iron salts through coprecipitation method at low-temperature led to the one-step gelatinization and retrogradation. The various characteristics of the nanocomposites hydrogel were examined including morphology and chemical structure besides magnetic, antimicrobial, and swelling behaviors. Further, the remaining ashes were considered as a simple method to estimate organic matter and inorganic nanoparticles content of hydrogel nanocomposite. The results indicated successful fabrication of a green hydrogel with magnetic and antibacterial features through a very simple method. The obtained ecofriendly hydrogel can be used in various applications such as controlled drug delivery, cancer hyperthermia, waste-water treatment, and many others.
