Multiscale Porosity Microfluidics to Study Bacterial Transport in Heterogeneous Chemical Landscapes

Microfluidic models are proving to be powerful systems to study fundamental processes in porous media, due to their ability to replicate topologically complex environments while allowing detailed, quantitative observations at the pore scale. Yet, while por ...

Non-invasive investigation of the morphology and optical properties of the upside-down jellyfish Cassiopea with optical coherence tomography

Anders Meibom, Niclas Heidelberg Lyndby, Sandrine Denise Françoise Bessette, Michael Kühl

The jellyfish Cassiopea largely cover their carbon demand via photosynthates produced by microalgal endosymbionts, but how holobiont morphology and tissue optical properties affect the light microclimate and symbiont photosynthesis in Cassiopea remain unex ...

Self-organized patterning of cell morphology via mechanosensitive feedback

Marko Popovic

Tissue organization is often characterized by specific patterns of cell morphology. How such patterns emerge in developing tissues is a fundamental open question. Here, we investigate the emergence of tissue-scale patterns of cell shape and mechanical tiss ...

Mechanical principles of engineering fibrous tissues with programmable shape

Erik Mailand

The form and structure of biological tissues define their function. The emergence of tissue morphology during development is one of the wonders of nature. Cells mechanically probe and manipulate their surroundings while constructing structures from the ext ...

Engineered Extracellular Matrices with Integrated Wireless Microactuators to Study Mechanobiology

Mahmut Selman Sakar, Erik Mailand, Nikolaos Bouklas, Fazil Emre Uslu

Mechanobiology explores how forces regulate cell behaviors and what molecular machinery are responsible for the sensing, transduction, and modulation of mechanical cues. To this end, probing of cells cultured on planar substrates has served as a primary ex ...

A perspective view on the nanomotion detection of living organisms and its features

Giovanni Dietler, Sandor Kasas, Anne-Céline Verenna Kohler, María Inés Villalba, Petar Stupar, Giovanni Longo, Leonardo Venturelli, Massimiliano Bertacchi

The insurgence of newly arising, rapidly developing health threats, such as drug-resistant bacteria and cancers, is one of the most urgent public-health issues of modern times. This menace calls for the development of sensitive and reliable diagnostic tool ...

Multimodal imaging combining time-domain near-infrared optical tomography and continuous-wave fluorescence molecular tomography

Edoardo Charbon, Scott Anthony Lindner, Chunmin Zhang, Martin Wolf, Jingjing Jiang, Markus Rudin

Fluorescence molecular tomography (FMT) emerges as a powerful non-invasive imaging tool with the ability to resolve fluorescence signals from sources located deep in living tissues. Yet, the accuracy of FMT reconstruction depends on the deviation of the as ...

Surface and bulk stresses drive morphological changes in fibrous microtissues

Mahmut Selman Sakar, Erik Mailand, Nikolaos Bouklas

Engineered fibrous tissues consisting of cells encapsulated within collagen gels are widely used three-dimensional (3D) in vitro models of morphogenesis and wound healing. While cell-mediated matrix remodeling that occurs within these scaffolds has been ex ...

Is desiccation tolerance and avoidance reflected in xylem and phloem anatomy of two coexisting arid-zone coniferous trees?

Alessandra Patera

Plants close their stomata during drought to avoid excessive water loss, but species differ in respect to the drought severity at which stomata close. The stomatal closure point is related to xylem anatomy and vulnerability to embolism, but it also has imp ...

Effect of mechanical damage and wound healing on the viscoelastic properties of stems of flax cultivars (Linum usitatissimum L. cv. Eden and cv. Drakkar)

Véronique Michaud, Sara Dalle Vacche, Federica Sordo

As plant fibres are increasingly used in technical textiles and their composites, underlying principles of wound healing in living plant fibres are relevant to product quality, and provide inspiration for biomimetic healing in synthetic materials. In this ...
