Which preservative is ideal for the long-term preservation of GNPs
you can use sodium nitrids NaN3, it has antimicrobial affect aganist various strains
The most important principle of keeping citrated gold nanoparticles is to prevent contamination with ions that can cause their aggregation. For this reason, you must use completely clean equipment washed with aqua regia and deionized water.
To store the solution of gold nanoparticles, put it in the refrigerator and in dark place.
The storage container should be glass and do not use metals.
If you store in plastic containers, they have already been treated with 12M NaOH.

Gold nanoparticles (AuNPs) possess inherent antimicrobial properties. The primary concern is preventing contamination by particulate matter rather than microbes. Therefore, follow the necessary precautions as suggested by Marjan Malekmohamadi . When you intend to reuse AuNPs, prepare a solution of the desired concentration and perform brief sonication. Currently, store the AuNPs only under refrigerated conditions (Because addition of any other chemical may bring out changes in pH and the electrolyte balance and change the physical properties of the particles).
Marjan Malekmohamadi Faslu Rahman C.K. Prakrutik Prafulchandra Bhavsar May I know when cell are treatewd with gold nanoparticles do i need to dilute them in control media so that the concentration of distilled water (I have colloid gold nanoparticles) by less than 1%?
