“…PMMA has excellent transparency, good abrasion resistance, hardness, ultraviolet resistance, and stiffness. Due to its attractive optical and electrical properties [29,30], PMMA is widely used in many applications such as lenses, light pipes, skylights, light emitting devices, and biomedical application [31]. PMMA is a biomaterial that has been utilized in clinical orthopedic practice and dental implants [32,33] for many years because of its non-degradable, hard, strong, rigid, and transparent character.…”

The understanding of interactions between nanomaterials and biological molecules is of primary importance for biomedical applications of nanomaterials, as well as for the evaluation of their possible toxic effects. Here, we carried out extensive molecular dynamics simulations of the adsorption properties of about 30 small molecules representing biomolecular fragments at ZnS surfaces in aqueous media. We computed adsorption free energies and potentials of mean force of amino acid side chain analogs, lipids, and sugar fragments to ZnS (110) crystal surface and to a spherical ZnS nanoparticle. Furthermore, we investigated the effect of poly-methylmethacrylate (PMMA) coating on the adsorption preferences of biomolecules to ZnS. We found that only a few anionic molecules: aspartic and glutamic acids side chains, as well as the anionic form of cysteine show significant binding to pristine ZnS surface, while other molecules show weak or no binding. Spherical ZnS nanoparticles show stronger binding of these molecules due to binding at the edges between different surface facets. Coating of ZnS by PMMA changes binding preferences drastically: the molecules that adsorb to a pristine ZnS surface do not adsorb on PMMA-coated surfaces, while some others, particularly hydrophobic or aromatic amino-acids, show high binding affinity due to binding to the coating. We investigate further the hydration properties of the ZnS surface and relate them to the binding preferences of biomolecules.

“…Including nanoparticles in PMMA has led to several commercial applications including photovoltaic devices, electronic printing, sensors, diodes, bone cement, and other biomedical materials. [9][10][11][12] This article highpoints fundamentals and characteristics of some important PMMA-based materials with carbonaceous fillers such as PMMA/carbon nanotube (CNT), PMMA/carbon black (CB), and PMMA/carbon fiber (CF). Recent applications of PMMA-based nanocomposite are in electromagnetic interference (EMI) shielding, gas sensors, separation membranes, tissue engineering, and drug delivery.…”

Poly(methyl methacrylate) is an important acrylic thermoplastic polymer. Poly(methyl methacrylate) is a transparent and rigid synthetic plastic. There has been growing interest in developing high performance poly(methyl methacrylate)-based nanocomposites. This article reviews a few important poly(methyl methacrylate)-based nanocomposites and composites. An extended account of the poly(methyl methacrylate) nanocomposites with carbonaceous nanofillers and fillers is given. The physical properties and how to manufacture poly(methyl methacrylate)/carbon nanotube, poly(methyl methacrylate)/carbon black, and poly(methyl methacrylate)/carbon fiber materials are appraised. The research so far shows that the mechanical, thermal, conducting, and microstructural performances improved compared with pure poly(methyl methacrylate). In order to further enhance the poly(methyl methacrylate) material performance, chemically modifying the carbonaceous fillers and chemical affinity with the polymer matrix are necessary. The main challenges here are to obtain well-dispersed, aligned, and easily processable poly(methyl methacrylate)-based composites. Poly(methyl methacrylate)-based nanocomposite applications are also reviewed in an attempt to facilitate progress in this emerging area. These materials are potential candidates in electromagnetic interference shielding, gas sensors, separation membranes, tissue engineering, and drug delivery applications.
