Micromechanical approaches have wide applications in biology and medicine due to the nature of biological tissues and the size of micro-biomedical devices. Micromechanical experiments, continuum micromechanics, and computational multi-scale models of materials with an emphasis on the connections between material properties and mechanical responses at a micron length scale are significantly essential to design and manufacture the mechanical components of micro-biomedical devices and comprehend the behaviour of biological tissues. The micro-scale mechanics of biological tissues is a multidisciplinary and rapidly expanding area of research, which deals with the lower-scale effects on the mechanical behaviour of biological tissues, such as bone, brain, muscle, vasculature, skin, etc. In fact, there are different micro-scale deformations, interactions, and movements within these tissues (e.g. microstructural or bi-phasic properties) affecting the mechanical response of the materials. The micromechanical characteristics of a material are key to find how it interacts with its physical environment, which eventually modulates the functionality of the material. Such micro-biomechanical effects stem from the structural and architectural arrangements and the hierarchical nature of biological tissues. This Virtual Collection presents the latest and cutting-edge experimental, computational, and theoretical research on the mechanical properties/behaviours of biological tissues and therapeutics to take into account the micro-scale effects, such as microstructures deformations, micro-scale inhomogeneity, micro-damage, micro-porosity, etc., and the mechanics of cells and cell-substrate interactions.</p><p>In this Virtual Collection, we received six manuscripts, six of which underwent peer review.
