The nanobipyramids and their seeds were prepared using the concentrated procedure39 (link). Tetrachloroauric acid trihydrate (99.99%), tetramethylguanidine (99%) and Catechol (98%), were procured from Alfa Aesar, while Citric acid monohydrate (99.5%), CTAC (25% in water), CTAB (99%, ref. H6269), and PEG2000-SH were obtained from Sigma-Aldrich. All vials, glassware, and magnetic stirrers underwent thorough cleaning with regal water and extensive rinsing in MilliQ water before usage. Magnetic stirrers were meticulously rinsed by sonicating them for a few minutes in MilliQ water twice, followed by storage in MilliQ water. Solutions of Catechol, particularly tetramethylguanidine (TMG), were prepared immediately before use. NaBH4/NaOH solutions, stored in the fridge at 5 M, were diluted to 50 mM in ice-cold water just before application.

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.
