Phycosynthesis of Silver Nanoparticles Using Cladophora Glomerata and Evaluation of Their Ability to Inhibit the Proliferation of MCF-7 and L20B Cell Lines

Abstract

Background: Nanotechnology is receiving greater attention these days as a result of its applications in numerous industrial, medical, and environmental fields. Objective: To synthesize silver nanoparticles with a green alga, Cladophora glomerata , and determine their inhibitory activity against tumor cell (MCF-7) and transgenic mouse cell (L20B) lines. Materials and Methods: Methanol extract was prepared from Cladophora glomerata and used as a safe factory for the synthesis of silver nanoparticles (AgNPs). UV-visible spectrophotometer, X-ray diffraction, scanning electron microscopy, and EDX analyses were used to characterize the biosynthesized AgNPs. The anti-tumor activity of the phycosynthesized AgNPs was tested against the MCF-7 and L20B cell lines. Furthermore, the bioactive compounds in the algal extract were determined by gas chromatography-mass spectroscopy (GC-MS). Results: The phycosynthesis produced clusters of spherical and polydispersed cuboidal pure AgNPs with an average size of 32 nm. The phycosynthesized AgNPs possess anti-cancer and anti-tumor activities on the MCF-7 and L20B cell lines, with significant anti-proliferation percentages of 52.8 and 65.8%, respectively, after 48 hours of treatment with 100 μg/ml AgNPs. Both treated cell lines showed a significant change in cellular shape and tissue detachment. The GC-MS analysis revealed the presence of a high proportion of octadecanoic acid (47.59%) and hexadecanoic acid (14.97%). Conclusion: Cladophora glomerata contains chemicals that improve the stabilization and reduction properties of the nanoparticles. It can be used as a safe, local, and natural source for the synthesis of AgNPs and can also be used as a benign factory for many other metal nanoparticles. The phycosynthesized AgNPs have anti-cancer and anti-tumor activities on the test cell lines and provide an insight into the potential for using them as a trend in cancer nanotherapy.

Phytochemical Characterization and Anticancer Screening of Cladophora goensis and Cladophora glomerata Extracts

“…29 The presence of hexadecanoic acid in C. glomerata was also reported by other studies. 30 Thus, these phytochemicals from the marine algae Cladophora spp. are good preliminary lead molecules for anti-cancer drug development.…”

Lychaete pellucida as a novel biosorbent for the biodegradation of hazardous azo dyes

“…A macroalga belonging to the chlorophyte class is L. pellucida , a fresh and marine green alga. This green alga’s main identifying features include a true branched filament that forms a net-like structure (Fayyad et al, 2022 ). Then, incredibly stiff filament often remains stable in a single location, making it simple to collect (Lefta et al, 2022 ).…”

Investigating the Properties and Cytotoxicity of Cisplatin-Loaded Nano-Polybutylcyanoacrylate on Breast Cancer Cells

“…Although chemotherapy is an effective treatment option, its toxic side effects, such as liver and kidney damage, immunosuppression, vomiting, hair loss, and more, can be significant limitations for patients. In addition, damage to normal tissues caused by tumor drugs is a major concern for individuals with breast cancer [16][17][18]. Cisplatin is a widely used chemotherapy drug effective against various types of cancer, including breast cancer.…”
