D. radiodurans R1 (ATCC13939) was grown aerobically at 32°C in tryptone glucose yeast (TGY) broth (0.5% tryptone, 0.1% glucose, 0.3% yeast extract) with agitation at 220 rpm. E. coli and S. aureus were grown at 37°C in Luria–Bertani (LB) medium (1% NaCl, 0.5% yeast extract and 1% tryp-tone). Bacterial growth was assessed by measuring optical density (OD) at 600 nm for D. radiodurans and E. coli and OD at 590 nm for S. aureus. Tetrachloroauric acid (HAuCl4·3H2O) was purchased from Sigma Aldrich Co. (St Louis, MO, USA). All reagents used were of analytical grade. A gold(III) stock solution was obtained by dissolving HAuCl4 in ultrapure water. The gold(III) solutions used in this study were prepared by dilution of a 10 mM HAuCl4 stock solution. The pH of each working solution was adjusted by hydrochloric acid or sodium hydroxide. Chloramphenicol was used as a control in the antibacterial assays.

Synthesis of AuNPs was carried out according to the procedures described in the citrate reduction method [17 (link),18 (link)]. Briefly, 0.0394 g of tetrachloroauric acid (HAuCl4·3H2O) (Sigma Aldrich Chemical Company, Atlanta, GA, USA) was dissolved in 100 mL of nanopure water (18 MΩ of resistance) in a three-neck round flask (1 mM HAuCl4) connected to reflux condenser. The resulting solution was isovolumetrically heated to boiling point under stirring and refluxed. Then, 10 mL of a 38.8 mM trisodium citrate solution was preheated to 60 °C and quickly added to the boiling solution of HAuCl4 under vigorous stirring. After the solution turned from pale yellow to black and to deep red, it was refluxed for additional 30 min and subsequently cooled to room temperature without stirring for at least 2 h. The formed nanoparticle suspension was filtered through Millipore Nylon filter (0.45 µm) and preserved in the dark at 4 °C for subsequent pH determination and characterization of the AuNPs.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
