{"title":"Novel Anticancer Platinum and Palladium Nanoparticles from Barleria prionitis","authors":"Sougata Ghosh","doi":"10.19080/gjn.2017.02.555600","DOIUrl":"https://doi.org/10.19080/gjn.2017.02.555600","url":null,"abstract":"Nanomedicines are emerging outcomes of nanobiotechnology which have promising pharmaceutical applications. Although there are various physical and chemical methods for synthesis of nanoparticles, most of them involve hazardous and toxic chemicals. Thus, there is a continuously growing need for investigation of novel routes to synthesize nanoparticles with enhanced biocompatibility and reduced toxicity. Medicinal plants are rich source of diverse photochemical responsible for simultaneous reduction and stabilization of nanoparticles. Herein, we report for the first time, the synthesis of platinum nanoparticles (PtNPs) and palladium nanoparticles (PdNPs) using Barleria prionitis extract (BPLE). PtNPs and PdNPs were characterized using UV-visible spectroscopy. High resolution transmission electron microscopy (HRTEM) revealed that the PtNPs were between 1 to 2 nm while PdNPs were between 5 to 7 nm. Further energy dispersive spectroscopy (EDS) and dynamic light scattering (DLS) confirmed the elemental composition and hydrodynamic size, respectively. Fourier transformed infrared spectra (FTIR) confirmed the involvement of diverse photochemical in reduction and stabilization of the nanoparticles. Both PtNPs and PdNPs were tested for anticancer activity against human breast adenocarcinoma (MCF-7) cell lines which showed reduced viability up to 60.08 ± 2.4 % and 57.22 ± 1.68 %, respectively. Further, flow cytometric studies and confocal microscopy using dual staining method with annexin V-FITC and propidium iodide indicated apoptosis induction as the plausible mechanism exhibiting externalization of phosphatidylserine and loss of cell membrane integrity. This is the first report on PtNPs and PdNPs synthesized by BPLE as promising anticancer agents.","PeriodicalId":427673,"journal":{"name":"Global Journal of Nanomedicine","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126398607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides mechanical robustness and cell-compatibility at the same time. Therefore, DLC has been extensively researched for achieving high hardness, low friction, high wear resistance to make it more sustainable [2]. Furthermore, DLC coatings are antithrombogenic and noncytotoxic. Consequently, they are being critically explored for various in-vivo and in-vitro biomedical applications ranging from orthopaedic applications to cardiovascular as well as neural interfacing agent. As such, DLC coatings has been certified as biocompatible in both in vitro and in vivo studies due to their strong C-C bonding environment [3,4].","PeriodicalId":427673,"journal":{"name":"Global Journal of Nanomedicine","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127562866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The imaging mass spectrogram indicates not spatial mass distributions but mass constitutions. Different masses draw annular ring patterns with respect to their existences and intensities on the same field of in the same time. The imaging mass spectrogram can be obtained by specific features of REFs type mass spectrometer; separates mass weight by filtering in high speed double REFs and draws annular ring patterns with direct continuous beam, simultaneously. The imaging mass spectrograms are mostly controlled by frequencies and intensities of REFs.
