Sono-Biosynthesis and Characterization of AuNPs from Danube Delta Nymphaea alba Root Extracts and Their Biological Properties. NANOMATERIALS (BASEL, SWITZERLAND) 2021; 11:1562. [PMID: 34198512 PMCID: PMC8231883 DOI: 10.3390/nano11061562] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 06/10/2021] [Accepted: 06/11/2021] [Indexed: 01/03/2023]
Abstract
Root extracts from Danube Delta Nymphaea alba were used to prepare gold nanoparticles (AuNPRn) by reducing HAuCl4 at different pHs (6.4-8.4) using ultrasonic irradiation: an easy, cheap, eco-friendly and green approach. Their antibacterial and anticancer activities were evaluated against Staphylococcus aureus and Escherichia coli, and A2780 ovarian cancer cells, respectively. The AuNPRn were characterized concerning their phytoconstituents (polyphenols, flavonoids and condensed tannins) and gold content. All of the nanoparticles were negatively charged. AuNPRn exhibited a hydrodynamic size distribution ranging from 32 nm to 280 nm, with the larger nanoparticles being obtained with an Au/root extract ratio of 0.56, pH 7 and 10 min of sonication (AuNPR1), whereas the smallest were obtained with an Au/root extract ratio of 0.24, pH 7.8 and 40 min of sonication (AuNPR4). The TEM/SEM images showed that the AuNPRn had different shapes. The ATR-FTIR indicated that AuNPRn interact mainly with hydroxyl groups present in the polyphenol compounds, which also confirm their high antioxidant capacity, except for AuNPR2 obtained at pH 6.4. Among the AuNPRn, the smallest ones exhibited enhanced antimicrobial and anticancer activities.

Investigation of bioactive compounds in Crassocephalum rubens leaf and in vitro anticancer activity of its biosynthesized gold nanoparticles. ACTA ACUST UNITED AC 2020; 28:e00560. [PMID: 33299809 PMCID: PMC7704417 DOI: 10.1016/j.btre.2020.e00560] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 09/29/2020] [Accepted: 11/14/2020] [Indexed: 12/24/2022]
Abstract
GC–MS analysis of Crassocephalum rubens extracts were investigated. Gold nanoparticles (AuNPs) were synthesized using aqueous extract of Crassocephalum rubens (AECR). DPPH radical scavenging activity of AECR was similar to that of AECR-AuNPs. AECR-AuNPs are potential anticancer agents against MCF-7 and Caco-2 cell lines.
The development of cancer therapies has become difficult due to high metastasis, and lack of tissue selectivity, which in most cases affects normal cells. Demand for anticancer therapy is therefore increasing on daily basis. Gold nanoparticles (AuNPs) have many applications in biomedical field. Biological synthesis of AuNPs using aqueous extract of Crassocephalum rubens (AECR) was designed to investigate the in vitro anticancer potential. The synthesized AuNPs were characterized by UV–vis spectroscopy, high-resolution transmission electron microscopy, and Fourier transform infrared spectroscopy. The characterization results showed the formation of green AuNPs of wavelength 538 nm, and mostly spherical AuNPs with 20 ± 5 nm size. Significant anticancer activity of the AECR-AuNPs on MCF-7 and Caco-2 cells was noted at higher concentrations (125 and 250 μg/mL) during 24 and at all concentrations tested during 48 h. It can therefore be concluded that AECR leaves can mediate stable AuNPs with anticancer properties.

Abstract
Potential applications of gold nanoparticles in biomedicine have increasingly been reported on account of the ease of synthesis, bioinert characteristics, optical properties, chemical stability, high biocompatibility, and specificity. The safety of these particles remains a great concern, as there are differences among toxicity study protocols used. This article focuses on integrating results of research on the toxicological behavior of gold nanoparticles. This can be influenced by the physicochemical properties, including size, shape, surface charge, and other factors, such as methods used in the synthesis of gold nanoparticles, models used, dose, in vivo route of administration, and interference of gold nanoparticles with in vitro toxicity assay systems. Several researchers have reported toxicological studies with regard to gold nanoparticles, using various in vitro, in vivo, and in ovo models. The conflicting results concerning the toxicity of gold nanoparticles should thus be addressed to justify the safe use of gold nanoparticles in biomedicine.
