“…The peak observed at 1040 cm -1 is typical characteristic peak of the SO groups in the AMPS units. While this peak was not observed in MAAm, it was determined that the intensity of this peak with the amount of AMPS added to the structure increased (Durmaz and Okay, 2000;Barati et al, 2013;Kousar et al, 2018). The FT-IR spectra of original MAAm and AMPS are shown in Figure 3 (b).…”

In this study, it was aimed that produce new polymeric hydrogels and that investigate the equilibrium swelling properties. Chemically crosslinked copolymeric hydrogels, composed of methacrylamide (MAAm) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were prepared via free radical copolymerization method. The obtained copolymeric hydrogels were characterized with FT-IR analysis and SEM techniques. In addition, swelling tests 25 o C were applied to all the synthesized samples and swelling characterization studies were performed. The influences of reaction variables such as monomer/co-monomer composition, crosslinker amount on swelling properties of hydrogels were investigated. When the swelling results are evaluated; It was observed that all polymeric samples showed different swelling and diffusion properties depending on their composition.

“…Three methods have been explored to determine the yield stress value: (1) extrapolation of the flow curves at low shear rates, (2) the Bingham equation, and (3) the Modified Bingham equation. Being the third one, the most commonly applied as it fits better to the experimental data of the hydrogel formulations [152], [153].…”

Novel additive manufacturing techniques are revolutionizing fields of industry providing more dimensions to control and the versatility of fabricating multi-material products. Medical applications hold great promise to manufacture constructs of mixed biologically compatible materials together with functional cells and tissues. We reviewed technologies and promising developments nurturing innovation of physiologically relevant models to study safety of chemicals that are hard to reproduce in current models, or diseases for which there are no models available. Extrusion-, inkjet-and laser-assisted bioprinting are the most used techniques. Hydrogels as constituents of bioinks and biomaterial inks are the most versatile materials to recreate physiological and pathophysiological microenvironments. The highlighted bioprinted models were chosen because they guarantee post-printing cellular viability while maintaining desirable mechanical properties of their constitutive bioinks or biomaterial inks to ensure their printability. Bioprinting is being readily adopted to overcome ethical concerns of in vivo models and improve the automation, reproducibility, geometry stability of traditional in vitro models. The challenges for advancing the technological level readiness of bioprinting require overcoming heterogeneity, microstructural complexity, dynamism and integration with other models, to generate multi-organ platforms that can inform about biological responses to chemical exposure, disease development and efficacy of novel therapies.
