“…The worst effect of AgNPs was observed at a concentration of 15 ppm. Therefore, our research confirmed the influence of the concentration of metal nanoparticles on antimicrobial properties, which was described by other authorshigher concentration of NPs increases their antimicrobial properties [58][59][60][61]. However, the concentrations of AgNPs, used in our research, were too low to completely inhibit the growth of microorganisms, because in all experimental trials, the presence of microbes was found.…”

Nanotechnology plays an important role in many fields of science and the economy. A special example of nanostructures is silver nanoparticles (AgNPs) created following the principles of green chemistry, i.e., without the use of toxic reducing compounds. The common tomato (Solanum lycopersicum) is a popular vegetable whose germination and growth process are studied by using, e.g., in vitro cultures. The aim of the experiment was to evaluate the inhibitory effect of the biodegradable gels containing silver nanoparticles on the development of microbial infection and to evaluate their influence on the germination degree of Tomato (Solanum lycopersicum) seeds in in vitro plant cultures. Based on macroscopic and microscopic observations, all experimental samples showed the presence of Gram-positive bacilli as well as mould fungi of the genus Rhizopus, Alternaria and Aspergillus. The study showed that the biocomponents containing silver nanoparticles obtained by using xylose as a reducing agent limit the development of microbial infection and stimulate the germination rate of tomato seeds. They could find their application as biodegradable raw materials in the production of modern disinfecting preparations for research in in vitro cultures. This study allowed to identify new research directions, especially to evaluate the metabolic regulation of seedlings treated with biodegradable silver nanoparticles.

“…Penggunaan daun mangrove jenis ini telah dilakukan sebagai capping agent pada studi sebelumnya (Willian et al, 2020). Oleh karena itu, perlu dilakukan kajian lebih lanjut untuk mengetahui bagaimana proses sintesis dan karakterisasi nanopartikel perak dengan buah mangrove Rhizophora stylosa, mengingat metabolit sekunder buah-buahan terkenal karena kandungan polifenolnya yang tinggi, di antaranya antosianin yang menempati posisi paling dominan (Mariychuk et al, 2020). Berdasarkan studi sebelumnya, belum pernah dilaporkan tentang sintesis nanopartikel perak menggunakan buah mangrove jenis Rhizophora stylosa sebagai bahan pereduksi yang ramah lingkungan.…”

Nanopartikel perak menampilkan sifat fisik dan biologis yang unik yang telah menarik minat penelitian karena aplikasi yang menjanjikan. Pada penelitian ini, proses fabrikasi nanopartikel perak(AgNPs) dilakukan dengan metode green sintesis menggunakan tanaman mangrove dengan pelarut air. Ekstrak buah mangrove Rhizophora stylosa (RS) pertama kali digunakan sebagai reduktor dan stabilizer dalam sintesis AgNPs. Karakteristik AgNPs ditentukan dengan spektrofotometer UV-Vis, FTIR, XRD dan TEM. Analisis spektrum UV-vis menunjukkan panjang gelombang pada 430 ‒ 445 nm. Studi FTIR mengungkapkan adanya senyawa fitokimia aktif yang bertindak sebagai zat penutup dan penstabil nanopartikel. TEM menunjukkan morfologi AgNPs yang ditemukan berbentuk bola dengan ukuran diamter sekitar 10 ‒ 60 nm. Pola XRD menunjukkan bahwa semua sampel AgNPs yang diperoleh memiliki struktur face-center cubic (fcc) yang menegaskan bahwa nanopartikel bersifat padatan kristalin dengan ukuran kristal 38 ‒ 77 nm. Studi ini membuktikan kemampuan biomaterial dalam sintesis AgNPs dengan mengadopsi prinsip sintesis hijau.Fabrication and Characterization of Silver Nanoparticles Using Extract of Mangrove Fruit of Rhizophora stylosa. Silver nanoparticles display unique physical and biological properties that have attracted research interest because of their promising applications. In this research, silver nanoparticle (AgNPs) fabrication process was carried out via green synthesis methods using mangrove plants and water as a solvent. Mangrove fruit extract Rhizophora stylosa (RS) was first used as a reducing agent and stabilizer in the synthesis of AgNPs. The characteristics of AgNPs were characterized using UV-Vis, FTIR, XRD, and TEM spectrophotometers. UV-vis spectrum analysis showed a peak at 430 ‒ 445 nm. FT-IR studies revealed the presence of active phytochemical compounds which act as coating agents and stabilizers for nanoparticles. TEM showed that the morphology of AgNPs was spherical with a diameter size of 10 ‒ 60 nm. The XRD patterns showed that all of the AgNPs sample obtained had a face-center cubic (fcc) structure, indicating that the nanoparticles are crystalline solids with a crystallite size of 38 ‒ 77 nm. This study proves the ability of biomaterials in the synthesis of silver nanoparticles by adopting the principle of green synthesis.

“…Metallic nanoparticles of silver (Ag), 23,24 gold, 25 copper, 26 and zinc oxide, 27 have also been studied to make wool textiles multifunctional including antibacterial. Instead of a toxic reducing agent, different types of tannins derived from pomegranate leaves, 28 elderberry fruits, 29 neem leaves, 30 black rice, 31 and Mentha spicata L., 32 were studied as a reducing agent. The advantage of silver nanoparticles (Ag NPs) is that they also can produce a variety of shades on treated fabrics depending on their shape and size.…”
