Here, electrolyte ions in solution rearrange to form electric double layers near the charged surface of a particle. Although overlapping double

According to classical Derjaguin–Landau–Verwey–Overbeek (DLVO) theory, the stability of the NMs is determined by two major contributions: the

Shorter alkanethiols (C2–C8) could not prevent aggregation and sedimentation of the nanoparticles; longer thiols (C12 & C14) resulted in higher colloidal stability. The effect was interpreted using an extended Derjaguin–Landau–Verwey–Overbeek (DLVO) theory that

The adsorption mechanism has been originally based on the Derjaguin–Landau–Verwey–Overbeck (DLVO) theory [58] that does not take into account both the base-sequence-dependent [59] and the salt-type-dependent adsorption. In particular, the latter has stimulated

Additionally, specific ion phenomena arise from different polarizabilities and Pearson acidities of the ions, leading to a variation of ion–solvent interactions [39]. Specific ion properties are summarized in the Hofmeister or lyotropic series [41][42
