Green synthesis of silver nanoparticles (AgNPs) provide superiority due to their usage of various biological applications. The aim of this study is synthesizing the silver nanoparticles by using Birch (Betula spp.) branches extract with an ecofriendly, cost-effective, simple, and cheap green method. Even Betula is wide-spread tree with rich in phenolic compounds, data on the use of Betula branches is limited. Within this scope, this study is the first for using Betula branche extracts which take part as reducing and capping agent to synthesize the silver nanoparticles to evaluate the antimicrobial activity and antiproliferative efficiency. The biosynthesized AgNPs were characterized by various characterization methods such as UV−visible spectroscopy, dynamic light scattering (DLS), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The characterization analysis has revealed the phenolic compounds of Betula extract acted as reducing and capping agent for formation of AgNPs. The synthesized selected AgNPs were exhibited spherical shape with 103.2 ± 5.2 and 69.2 ±12.7 nm according to DLS and SEM analysis, respectively. Also, the biological activity of biosynthesized AgNPs were evaluated by antimicrobial and antiproliferative tests on selected microorganisms and cell line, respectively. The IC50 values of B3-4 AgNPs was determined as 64.27 µg/mL on HT29 colorectal cancer cells. And also, the antimicrobial activity results of AgNPs have revealed the dose-dependent inhibition for all studied test microorganisms. In conclusion, this study evidently suggests the use of silver nanoparticles biosynthesized from Betula branches extract as a potential agent for antimicrobial and anticancer studies.

This study aimed to evaluate the concept of green synthesis of metallic nanoparticles (silver nanoparticles, AgNPs) by plant extracts without using any toxic or hazardous materials. Alchemilla vulgaris (AV) and Helichrysum arenarium (HA) are used as capping and reducing agents to synthesize AgNPs (as coded AV-AgNPs and HA-AgNPs). Both synthesized AgNPs were characterized by UV–visible spectrophotometry, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and transmission electron microscope (TEM). The results of characterization exhibited that AgNPs were successfully synthesized. They are highly well-dispersed, mostly spherical shape with an average size 15–20 nm. Catalytic reduction of methylene blue (MB) and 4-nitrophenol (4-NP) was assessed using synthesized AgNPs as nano-catalysts in the presence of NaBH4. The catalytic activity of the synthesized AgNPs revealed significant results in terms of degradation of MB and 4-NP to 4-AP (4-aminophenol). The reduction reactions of MB and 4-NP happen within 6–7 min using synthesized AV-AgNPs and HA-AgNPs in the presence of NaBH4. According to the reusability analysis, synthesized AgNPs demonstrated excellent degradation performances by the more than 94% removal efficiency maintained after five reuse cycles. In addition, antibacterial activities of AgNPs were investigated against Escherichia coli (E. coli; Gram-negative bacteria) and Staphylococcus aureus (S. aureus; Gram-positive bacteria) by using quantitative well-diffusion method and the inhibition zones were determined using Mueller–Hinton agar (MHA) media. AV-AgNPs and HA-AgNPs showed strong antibacterial activities against E. coli with in inhibition zone diameters 25.5 and 25 mm, respectively. AV-AgNPs and HA-AgNPs were also extremely effective on S. aureus with high inhibition zone values of 22 and 24 mm, respectively. Finally, the fabricated silver nanoparticles could be excellent candidates for the separation of hazardous materials.
