Document Title:New Guide for Sample Preparation of Charge-Stabilized Metal Nanoparticles for Electron Microscopy
url:http://www.astm.org/DATABASE.CART/WORKITEMS/WK39049.htm
Scope:This guide establishes a standard method for the preparation of stabilized metal particle samples, which are solely or predominantly sub-100 nm, for electron microscopy to allow for accurate and reproducible measurement of particle size. Specifically, it provides a general overview to the use of functionalized substrates for the microscopy of metal particles that are suspended, dissolved, or otherwise dispersed in aqueous solvent and have a positive or negative surface charge. Examples of such materials include citrate-stabilized (negative) gold or silver nanoparticles, polyvinylpyrrolidone-stabilized (negative) metal particles, or poly-l-lysine-stabilized (positive) particles. No existing standard in this area.
