After tissue homogenisation in a ball mill, we found signicantly higher DNA concentration than mortar and pestle usage but no signicant differences in RNA concentration and DNA and RNA purity ratios.
Meniran extract with each concentration of 5%, 10% and 20% was taken 25 ml and then added to 250 grams of minerals containing amino acids and multivitamins, then nanoparticles synthesis was carried out by top-down milling method. The powder-loaded ball mill and the ambient balls are rotated at a speed of 1000 rpm.
