title: Data related to Fabrication of innocuous gold nanoparticles using plant cells in culture – A novel approach, including particle size analysis, catalytic activity and toxicology

description: This data set contains data on PCR primers, FACS analysis, cytotoxicity, particle size analysis, catalytic activity, chromatography, MTT assay and infrared spectroscopy, created and analysed during a study of the fabrication of innocuous gold nanoparticles using plant cells in culture.<br>The related research article describes the development and testing of a novel method for the fabrication of gold nanoparticles (AuNPs) using cell suspension culture of the plant <i>Medicago sativa. </i>This technique is designed as a cost effective and environmentally friendly alternative to physical and chemical methods of nanomaterial synthesis. <i>M. Sativa</i> is utilised for its property of accumulating heavy metals, where the use of cell suspension culture provides useful controlled conditions for particle isolation, compared to the more laborious process of growing entire plants under controlled conditions for this purpose.<br>As toxicity is a significant aspect of this process, often dependent on physical dimensions and surface chemistry of AuNPs, the immunological response to derived nanoparticles in this study was also investigated in a murine model.<b><br></b><b>Methods</b><br>This section provides background to the files held in this data record, for a detailed description of the study methods see the related publication.<br><i>M. Sativa </i>hypocotyl regions were extracted into a continually growing plant cell culture, a single cell suspension culture was then tested for KAuCl<sub>4</sub> tolerance, before supplementing with KAuCl<sub>4 </sub>for AuNP synthesis and recovery of AUNPs, including FT-IR spectroscopy to detect particle presence. Absorbance analysis was then performed for testing of catalytic activity and MTT assay testing for cytotoxicity of nanoparticles in human and mouse cell lines. Morphological analysis of particles was performed via Electron microscopy and cytokine detection in lab mice via ELISA.<br><br><b>Data set contents:</b><br><b>Real time PCR primers.docx</b> - MS Word file holding PCR primers for transcript analysis.<b>Absorbance of column fractions.xls - </b>MS Excel spreadsheet holding absorbance of ten eluted column fractions vs wavelength in nm.
