Mechanical stimuli are known to play critical roles in mediating tissue repair and regeneration. Recently, this knowledge has led a paradigm shift toward proactive programming of biological functionalities biomaterials by leveraging mechanics–geometry–biofunction relationships, which beginning shape the newly emerging field mechanobiomaterials. To profile field, article aims elucidate fundamental principles modulating responses with material–tissue mechanical interactions, illustrate recent findings on relationships between material properties responses, discuss importance mathematical/physical models numerical simulations optimizing geometry, outline design strategies for mechanobiomaterials their potential Given that is still its infancy, also discusses open questions challenges need be addressed.

The development of next generation soft and recyclable materials prominently features dynamic (reversible) chemistries such as host-guest, supramolecular, covalent. Dynamic systems enable injectability, reprocessability, time-dependent mechanical properties. These properties arise from the inherent relationship between rate equilibrium constants (RECs) molecular junctions (cross-links) resulting macroscopic behavior networks. However, few examples explicitly measure RECs while exploring this connection material properties, particularly for polymeric hydrogel systems. Here we use covalent imine formation to study how single-point compositional changes in NH

Abstract The combined use of Low Frequency-Pulsed Electromagnetic Field (LF-PEMF) and magnetic nanoparticles (MNPs) represents an innovative approach for biomedical applications in recent years. Also, the surface properties MNPs play a crucial role understanding how they will interact with biological systems determining their suitability intended applications. aim this study was to evaluate interactions different charges adipose-derived mesenchymal stem cells (AD-MSCs) under LF-PEMF stimulation. Intracellular localization vitro cytotoxicity surface-modified were examined through interaction AD-MSCs. Calcium histochemical analysis performed investigate synergistic effect LF-PEMF. It determined that application (50 µg/mL) (1.3 mT, 15 Hz) did not demonstrate cytotoxic on modification ensured homogeneous distribution within cells, cationic being predominantly localized around nucleus, while anionic dispersed cytoplasm. Furthermore, exposure influenced cell morphology, leading increased cytoplasmic extensions, particularly interacting silica-coated MNPs. These results shed light importance stimulation pave way future studies. Graphical abstract
