Protein loaded mesoporous silica spheres as a controlled delivery platform

Abstract

BACKGROUND: The adsorption of bovine serum albumin (BSA) onto mesoporous silica spheres (MPS) synthesized from silica colloids was studied employing real time in situ measurements. The stabilities of the BSA at different pH values, their isoelectric points and zeta potentials were determined in order to probe the interactions between the protein and the mesoporous silica.

Preparation of capped silver nanoparticles using sunlight and cationic surfactants and their biological activity

“…2 [23,37,22]. By inspection of data in Table 2, it was found that the zeta potential values of capped AgNP susingthe prepared cationic surfactants are greater than +30 mV, which is an indication of the high stability of prepared AgNPs against agglomeration [38]. The high value of the zeta potential also indicates the electrostatic repulsion between the formed particles increase, keeping particles free from agglomeration and stable for long periods.…”

Anticancer cytotoxicity assessment of cationic surfactants metal complexes

“…The fact that complex particles push each other and their agglomeration behavior depends on large negative or positive zeta potential. The zeta potential playing an important role limits in the stability of solutions is +30 mV or -30 mV [19]. The zeta potential of the synthesized metal complexes (representatively for VSBO complexes of Y(III), Ni(II), Co(II), and Cu(II) are always in positive values and higher than 50 mV.…”

Performance of the submerged membrane electro-bioreactor (SMEBR) with iron electrodes for wastewater treatment and fouling reduction

“…It was reported that large negative and positive zeta potentials indicate stable suspensions, which prevent the flocs' formation. A dividing line between stable and unstable aqueous suspension can be drawn at zeta potential either +30 or −30 mV [14]. Therefore, the dramatic changes in the zeta potential values in Stage II led to an improvement in permeation flux within the SMEBR system.…”
