“…Among the alternative materials identified in this systematic review, PMMA appears to be a good option and is cited in three publications. PMMA is the acrylate-family polymer known for fracture resistance, translucency, and elasticity [ 86 ], as well as high chemical resistance [ 87 ]. In addition, PMMA is a low-cost and easily manufactured material [ 88 ]; it is also less hydrophobic than PDMS or other polymers used in microfluidic devices, thus ensuring a lower absorption of hydrophobic molecules crucial characteristics for the preservation of cell culture.…”

Microfluidics and organ-on-a-chip technologies: A systematic review of the methods used to mimic bone marrow

et al. 2020

Bone marrow (BM) is an organ responsible for crucial processes in living organs, e. g., hematopoiesis. In recent years, Organ-on-a-Chip (OoC) devices have been used to satisfy the need for in vitro systems that better mimic the phenomena occurring in the BM microenvironment. Given the growing interest in these systems and the diversity of developed devices, an integrative systematic literature review is required. We have performed this review, following the PRISMA method aiming to identify the main characteristics and assess the effectiveness of the devices that were developed to represent the BM. A search was performed in the Scopus, PubMed, Web of Science and Science Direct databases using the keywords ((“bone marrow” OR “hematopoietic stem cells” OR “haematopoietic stem cells”) AND (“organ in a” OR “lab on a chip” OR “microfluidic” OR “microfluidic*” OR (“bioreactor” AND “microfluidic*”))). Original research articles published between 2009 and 2020 were included in the review, giving a total of 21 papers. The analysis of these papers showed that their main purpose was to study BM cells biology, mimic BM niches, model pathological BM, and run drug assays. Regarding the fabrication protocols, we have observed that polydimethylsiloxane (PDMS) material and soft lithography method were the most commonly used. To reproduce the microenvironment of BM, most devices used the type I collagen and alginate. Peristaltic and syringe pumps were mostly used for device perfusion. Regarding the advantages compared to conventional methods, there were identified three groups of OoC devices: perfused 3D BM; co-cultured 3D BM; and perfused co-cultured 3D BM. Cellular behavior and mimicking their processes and responses were the mostly commonly studied parameters. The results have demonstrated the effectiveness of OoC devices for research purposes compared to conventional cell cultures. Furthermore, the devices have a wide range of applicability and the potential to be explored.

“…Acrylic polymers are macromolecules that are formed mainly by the acrylate or methacrylate functional group (Figure 8). These polymers tend to form a versatile set of materials, which also exhibit great biocompatibility, and thus are used extensively on medical applications (Serini, 2012).…”

The present review compiles different biomedical relevant polymers that have been modified to enhance their properties, giving hydrophilicity to their surfaces, antifouling properties to avoid bacterial adhesion, biocompatibility, incorporation of drug delivery systems and the improving of their mechanical properties to use them in the manufacturing of medical devices as prosthesis or implants, or other medical applications as wound dressers or scaffolds to cell culture. Other content of this work is a general description of the different techniques to modify and graft molecules, biomolecules and other polymers onto polymeric matrices in order to obtain highperformance biomaterials and medical devices.

“…However, it become insoluble when polymerize due to the formation of strong polymer-polymer H bonds [ 11 ]. Moreover, it is considered a hard monomer due to the high T g of its homopolymer, 105 °C [ 12 ]. As shown the Figure 1 , the ACN has both the nitrile group and a double bond in the same molecule, which makes this monomer highly reactive and, for this reason, it must be inhibited on storage against polymerization [ 12 , 13 ].…”

A series of pressure-sensitive adhesives (PSA) were prepared by emulsion polymerization in order to obtain a PSA that meet with the current label market requirements. For it, the effect of the incorporation of acrylonitrile (ACN) as hard monomer was investigated in a n-butyl acrylate (n-BA) and acrylic acid (AA) system. Great differences were found in the adhesive performance according to the ACN weight ratio. Its increased resulted in a considerable rise in the average sol molecular weight and in the glass transition temperature. This was reflected in a decrease of adhesion forces (peel resistance and tack) and an increase of the cohesion forces (shear resistance). Moreover, the incorporation of the minimum amount of ACN studied showed a great change in the elastic modulus determined by dynamic shear resistance with respect to the based formulation that did not contain ACN. Finally, the ice bucket test was carried out to check the adhesive performance in cold and wet environments.
