“…These approaches rely on spontaneous or directed self-assembly and atoms to new nuclei that grow into NPs. , In particular, the bottom-up approach comprises chemical and electrochemical reduction, sonochemical and thermal decomposition, and cryo-chemical synthesis methods . Chemical reduction is the most common scheme used for synthesizing AgNPs among the described bottom-up approaches, wherein different organic and inorganic reducing agents, such as sodium borohydride (NaBH 4 ), , sodium citrate and ascorbate, Tollen’s reagent, N , N -dimethylformamide (DMF), and poly(ethylene glycol), block copolymers are used for the reduction of Ag + in aqueous (water) or nonaqueous (organic) solutions. , Additionally, some capping agents are also used to gain precise control over the size and shape of NPs. The chemical synthesis methods are facile, one-step, inexpensive, and give a high yield.…”

Silver nanoparticles (AgNPs) can be used to treat many clinical challenges due to their resourceful medicinal properties present in them. Moreover, AgNPs exhibits unique optoelectronic properties, distinct chemistry, high surface-to-volume ratio, and high avidity, making them principally suitable for healthcare applications. In the present perspective, size and shape-based AgNPs antimicrobial action are reviewed. Furthermore, the intrinsic features and plausible toxicity of AgNPs with emerging applications across daily life and healthcare categories are discussed. This perspective urges researchers to focus on the hazards of AgNPs before their utilization to deal with human diseases. Moreover, additional studies have been suggested concerning the sustainable engineering of nanoparticles toward safety and quality in human health complications. All these concerns are still considered a challenge because nanoparticle characterization is still in its infancy for implementation in human life. Finally, this perspective provides a scientific foundation for the construction of global accord guidelines in the future.

“…Salah satu cara untuk menghindari proses aglomerasi ialah dengan penambahan agen penstabil seperti senyawa surfaktan. Salah satu senyawa surfaktan yang pernah digunakan pada sintesis nanopartikel perak melalui pereaksi Tollens adalah natrium di(2-etilheksil) sulfosuksinat (AOT) (Kienskaya et al, 2011). Pada sintesis yang dilakukan tidak digunakan agen penstabil sehingga nanopartikel yang dihasilkan mengalami aglomerasi.…”

Zeolit adalah mineral aluminosilika berpori mikro sehingga memiliki permukaan yang luas. Permukaannya yang luas menyebabkan zeolit umum digunakan sebagai adsorben. Zeolit X termasuk dalam struktur Faujasit dan biasa mengikat kation natrium. Kation yang terikat pada zeolit dapat ditukar dengan kation lainnya, seperti kation logam transisi. Kation logam transisi seperti [Ag(NH3)2]+ biasa digunakan sebagai pendeteksi gugus aldehida atau biasa dikenal sebagai pereaksi Tollens. Penelitian ini bertujuan menyintesis komposit adsorben zeolit X/oksida perak dan zeolit X/oksida tembaga melalui reaksi Tollens. Komposit dikarakterisasi menggunakan scanning electron microscope menunjukkan permukaan milik komposit lebih kasar dari pada permukaan zeolit X. Bahan yang digunakan sebagai model untuk adsorpsi ialah, gas amonia. Komposit yang dihasilkan ada tiga jenis berdasarkan tahapan penambahan zeolit pada proses sintesis, yaitu setelah penambahan prekursor (komposit 1), setelah penambahan NH4OH (komposit 2), dan setelah pemanasan (komposit 3). Komposit yang dihasilkan mampu meningkatkan adsorpsi amonia hingga 2 kali lipat daripada zeolit X.
