We are thinking of dispersing nanomaterials in brine? What type of materials and stabilisation mechanisms will be good?
Hi there,
See attached files may be as answer for your question.

To prepare diopside scaffolds by the SH method, NaCl as the spacer with various particle sizes (250–300, 300–420, 420–600 and >600 µm) was added to the diopside nanopowder. This method involves four steps (Arifvianto and Zhou, 2014b): mixing of the matrix powder (the matrix can be either ceramic or metal) and the spacer particles, compaction of the obtained powders, sintering of the compacted sample, and finally removal of the spacer using deionized water (If the matrix is metal, at first the spacer is removed and then the sintering process is applied).
Dear Sir,

The inputs here helped me to look at applications of nanomaterials in biological medium. I understand that the nanoparticles tend to agglommerate in biological medium. What is the reason for this?
Is bacterial growth medium like lysogeny broth (LB) medium salty

Some papers talk about the influence of bacteria on agglommeration of nanoparticles

Some papers talk about how salt nanoparticles can be dispersed in a medium
https://www.beilstein-journals.org/bjnano/articles/3/30
But what I am interested is in to see whether presence of salt causes agglomeration of nanoparticles and how it can be mitigated?
Dear Sir,
Please See the attached article

the problems with the brine are
it kills electrostatic stabilization (screening of charges)
it kills common steric stabilization by dehydrating hydrophilic polymer segments.
