Green Synthesis, Optimization, and Characterization of Silver Nanoparticles using Helichrysum Extract

Abstract

Silver nanoparticles are used in many fields such as drug delivery systems, biomedical applications, cancer treatments, cosmetics and food thanks to their uniqe chemical and physical properties. Silver nanoparticles can be synthesized in 3 different ways: physical, chemical and biological. In recent years, researchers have turned to green synthesis because it is environmentally friendly, reliable and biocompatible. In this context, a new method for the synthesis of silver nanoparticles was proposed in this study using Helichrysum extract, a natural phytochemical source. The effects of silver ion concentration, Helichrysum extract concentration and reaction time on nanoparticle formation were investigated and optimum reaction conditions were determined. Silver nanoparticles synthesized in the presence of the synthesized Helichrysum extract were characterized using ultraviole (UV) spectrophotometry and the dynamic light scattering (DLS) analysis. Respect to the UV spectrophotometric results, the synthesized light yellow silver nanoparticles showed maximum absorption at 440 nm wavelength. According to DLS analysis results, homogeneous and spherical nanoparticles with an average size of 54 nm were successfully synthesized. The proposed green nanotechnology-based synthesis method is novel, simple, rapid, low-cost, sustainable, and eco-friendly.

Ölmez Çiçek Ekstresi Kullanılarak Gümüş Nanoparçacıkların Yeşil Sentezi, Optimizasyonu ve Karakterizasyonu

Öz

Gümüş nanoparçacıklar, benzersiz kimyasal ve fiziksel özellikleri sayesinde ilaç taşıma sistemleri, biyomedikal uygulamalar, kanser tedavileri, kozmetikler ve gıdalar gibi birçok alanda kullanılmaktadır. Gümüş nanoparçacıklar fiziksel, kimyasal ve biyolojik olmak üzere üç farklı şekilde sentezlenebilir. Son yıllarda araştırmacılar, çevre dostu, güvenilir ve biyouyumlu olması nedeniyle yeşil senteze yönelmiştir. Bu bağlamda, bu çalışmada doğal bir fitokimyasal kaynak olan Helichrysum ekstresi kullanılarak gümüş nanoparçacıkların sentezi için yeni bir yöntem önerilmiştir. Nanoparçacık oluşumu üzerinde gümüş iyon konsantrasyonunun, Helichrysum ekstresi konsantrasyonunun ve reaksiyon süresinin etkileri araştırılmış ve optimum reaksiyon koşulları belirlenmiştir. Helichrysum ekstresi varlığında sentezlenen gümüş nanoparçacıklar, ultraviyole (UV) spektrofotometri ve dinamik ışık saçılması (DLS) analizi kullanılarak karakterize edilmiştir. UV spektrofotometri sonuçlarına göre, sentezlenen açık sarı gümüş nanopartikülleri 440 nm dalga boyunda maksimum absorpsiyon göstermiştir. DLS analiz sonuçlarına göre, ortalama 54 nm boyuta sahip homojen ve küresel nanoparçacıklar başarıyla sentezlendi. Önerilen yeşil nanoteknoloji esaslı sentez yöntemi yeni, basit, hızlı, düşük maliyetli, sürdürülebilir ve çevre dostudur.
