An aggregated
silica particle hydrogel was formed from a filtered 9 wt % (4.1 vol
%) colloidal suspension of amorphous silica nanoparticles (Bindzil
40/130; AkzoNobel, PPC AB, Bohus, Sweden).^{39 (link),40 (link)} In short, the gelation process was triggered by adjusting the pH
from 9.1 to 7.8 and by adding NaCl (s) to a final concentration of
0.5 M NaCl (aq). The gel was left to set for 2 weeks before electron
microscopy preparation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
