文献和实验Preparation of 2 nm Gold Nanoparticles for In Vitro and In Vivo Applications
Gold nanoparticles have been a versatile tool in recent years for the exploration of biological systems. However, challenges with purification and adequate surface coverage limit the biocompatibility of gold nanoparticles
Preparing Colloidal Gold for Electron Microscopy
and store at -70°C. To determine the concentration at which to use the protein A gold, measure the optical density (OD) at 520 nm of a 1:100 diluted solution in PBS. Use a dilution with an O.D. of between 0.05
size. Gold sols can be made in the laboratory that have a particle size ranging from 2 to 40 nm, depending on the type and concentration of the reducing agent. The methods given below for various sizes of gold are relatively simple and very reproducible
