“…Refined MMT has been studied for various common health applications, such as cosmetics [ 7 , 8 ], wound dressings [ 9 , 10 , 11 , 12 , 13 ], and anti-diarrhea medicines [ 14 ], owing to the uniform bidimensional particle shapes, high length-to-height ratios, inherent stiffness, dual charge distribution, chemical inertness, biocompatibility, and active sites on the surface [ 15 , 16 , 17 , 18 ]. The results of these studies have attracted the interest of scientists and biotechnologists since micro/nanosized materials might also exhibit the same micro/nano biological interactions because one functional dimension is outside the nanoscale range of 1 nm to 100 nm, whereas organ-modified micro/nanosized materials might have uncertain effects on micro/nanobiological interactions [ 19 , 20 , 21 , 22 ].…”

Montmorillonite has been refined to overcome uncertainties originating from different sources, which offers opportunities for addressing various health issues, e.g., cosmetics, wound dressings, and antidiarrheal medicines. Herein, three commercial montmorillonite samples were obtained from different sources and labeled M1, M2, and M3 for Ca-montmorillonite, magnesium-enriched Ca-montmorillonite, and silicon-enriched Na-montmorillonite, respectively. Commercial montmorillonite was refined via ultrasonic scission-differential centrifugation and labeled S, M, or L according to the particle sizes (small, medium, or large, respectively). The size distribution decreased from 2000 nm to 250 nm with increasing centrifugation rates from 3000 rpm to 12,000 rpm. Toxicological evaluations with human colon-associated cells and human skin-associated cells indicated that side effects were correlated with excess dosages and silica sand. These side effects were more obvious with human colon-associated cells. The microscopic interactions between micro/nanosized montmorillonite and human colon-associated cells or human skin-associated cells indicated that those interactions were correlated with the size distributions. The interactions of the M1 series with the human cells were attributed to size effects because montmorillonite with a broad size distribution was stored in the M1 series. The M2 series interactions with human cells did not seem to be correlated with size effects because large montmorillonite particles were retained after refining. The M3 series interactions with human cells were attributed to size effects because small montmorillonite particles were retained after refining. This illustrates that toxicological evaluations with refined montmorillonite must be performed in accordance with clinical medical practices.

“…In recent years, inorganic materials have been targeted as very particular alternatives by virtue of their prospects as antibacterial agents. Several studies have suggested that clay-based nanocomposites are effective, biocompatible, inexpensive, and stable materials for treating various pathogens [5][6][7][8][9][10][11][12][13].…”

This review provides information on the latest advances in inorganic materials with antimicrobial properties based on a metallic species immobilized on the clay mineral montmorillonite realized between the years 2015 and 2023. This class has shown many promising results compared to certain organic agents. Montmorillonite in natural and/or modified forms is a good platform for the storage and release of metallic species, and several researchers have worked on this mineral owing to its cation exchange capacity, low cost, biocompatibility, and local availability. The preparation methods and the properties such as the antibacterial, antifungal, and toxicological activities of this mineral are discussed. The main characteristics of this antibacterial class for the elimination of pathogenic bacteria were examined and the known weak points of its antimicrobial application are discussed, leading to suggestions for further research.
