is it possible for sublimation by the help of lyophilizer ? or hot air oven?
To dry chitosan-coated silver nanoparticles for characterization, you can consider the following methods:
Regardless of the drying method chosen, it is important to consider the stability of the chitosan-coated silver nanoparticles during the drying process. Factors such as temperature, time, and exposure to air can potentially affect the properties and characteristics of the nanoparticles. It is advisable to evaluate the stability and integrity of the nanoparticles post-drying using appropriate characterization techniques, such as transmission electron microscopy (TEM), dynamic light scattering (DLS), or UV-Vis spectroscopy, to ensure that the drying process does not significantly alter their properties.
Additionally, it is crucial to follow safety guidelines and handle nanoparticles in a controlled environment to prevent any potential health or environmental hazards.
Lypholization is one of the best method i have tried and tested and published it too
Vacuum over will be best to avoid any thermal and chemical degradation of coating.
