When stored as recommended, most nanoparticles remain stable for at least 12 months from date of manufacture. Always visually inspect your materials before each use. If you notice any visible particulates, a change in the solution’s color, or a decrease in color intensity, the nanoparticles may have aggregated. Analyze these materials using UV-Visible spectroscopy, DLS, or TEM for quality verification or contact our technical team info@sonanano.com
