The mechanical property and behavior of the lipid membrane is ubiquitously relevant to cellular processes. Studies in these areas find wide applications in cellular biophysics, pathology, and bio-inspired engineering. Recent work focuses on exploring membrane response via deformation-based assays, including a variety of techniques such as optic tweezing, micro-pipetting, electrodeformation, and flow-based deformation. In this minisymposium, we aim to bring together forefront research in both vesicle and cell mechanics. The former, which is a self-enclosed lipid membrane or liposome, is often employed as a model system to explore salient and relevant features and functionalities. The presentations will discuss recent progresses to understand the challenging mechanical problems that involve fluid-structure interactions and/or how these results can be applied to engineering applications. Importantly, this forum attempts to catalyze interactions between the vesicle and cell research communities: the former has frequently a strong focus on the simple yet fundamental physical aspects, whereas the later are often from a proper biological/pathological perspective.
