A Clean-Green Synthesis of Platinum Nanoparticles Utilizing a Pernicious Weed Lantana (<i>Lantana Camara</i>)

Abstract

A rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to platinum nanoparticles and leaf extract then served the additional purpose of stabilizing the nanoparticles. The resulting nanoparticles have an average size of 35 nm and crystallized in face centred cubic symmetry. The course of the synthesis was trekked by UV-visible spectrophotometry and the characterization of the nanoparticles was done with scanning electron microscopy and confocal laser Raman spectroscopy. Particle size distribution was estimated by dynamic light scattering and the crystal structure was determined by XRD. The purity of the product was checked by EDAX.

Synthesis and characterisation of novel biopolymer stabilised organic Pt‐nanocomposite: assessment of its antioxidant and antitumour properties

“…The first observation of GKCPt NC formation is the visually distinct black coloured solution of NC within the GK bio‐template. These observations were confirmed by UV–vis spectrophotometer analysis and no SPR was observed in GKCPt NC in agreement with earlier reports [21, 71] that Pt has strong d‐electron excitations which increase the complex dielectric constants ɛ 1 and ɛ 2. The UV spectrum of carboplatin showed a strong one absorbance peak corresponding to the Pt 2+ ions at 230 nm (Fig.…”

Lantana camara Linn root extract-mediated gold nanoparticles and their in vitro antioxidant and cytotoxic potentials

“…The weed, L. camara Linn, has various medicinal applications which were contributed with earlier synthesized nanoparticles by several researchers (;;; Ajitha et al 2015;Dash et al 2015;Kumar et al 2016a, b, c;Mavukkandy et al 2016;Kamarasamyraja and Jaganathan 2013;Sivakumar et al 2012;Thirumurugan et al 2011). Their results described about multi-potentials of L. camara which opened up its use in biomedical applications.…”

“…Therefore, it is of urgent need to develop novel therapeutic agents that are biocompatible and cost-effective (Franco-Molina et al 2010). Though, there have been plenty of reports on synthesis of nanoparticles from L. camara Linn by several researchers (Ajitha et al 2015;Dash et al 2015;Kumar et al 2016a, b, c;Kamarasamyraja and Jaganathan 2013;Mavukkandy et al 2016;Sivakumar et al 2012;Thirumurugan et al 2011), this is the first attempt to synthesize Au NPs using the root aqueous extract of L. camara Linn to evaluate its antioxidant as well as cytotoxic effect on human breast cancer cell line (MDA-MB-231) by MTT assay, and the possible mechanism for cell death was addressed through acridine orange and ethidium bromide (AO/EB) dual staining and DNA fragmentation assays.…”
