We converge a biomimetic design strategy inspired in the architecture of natural soft tissues and a novel additive manufacturing technology termed melt electrowriting (MEW) to manufacture advanced biomimetic soft network composites (BSNC). The SNCs are composed of a weak polymer matrix and a MEW reinforcing fibrous phase printed at the nanometre scale, containing patterns mimicking the natural tissue architectures. Advanced computational tools are applied for the rational design of the SNC while reducing costs and times associated to experimental work.Read moreRead less

This project aims to develop novel magnetic resonance imaging methods to investigate tissue structure and function. Current MRI technologies use standard water-based contrast mechanisms to generate images with limited tissue information. In contrast, this project expects to provide a non-invasive, ultra-high-resolution MRI technology that measures the electrical, magnetic, and chemical signals generated from the human body. Thus, the new imaging methods can probe deeper biological functionality while examining tissue structure. The potential benefits include: expanding the scope and capabilities of current MRI, facilitating a wide range of imaging-based research and applications, and accelerating knowledge expansion in life science.Read moreRead less

This cell behaviour control will be accomplished through an interdisciplinary and multiscale pipeline of additive micromanufacturing, bioreactor engineering, cell culture, single-cell imaging, and computational modelling. In contrast with current empirical approaches, this quantitative and predictive understanding of how to control biological processes within 3D printed environments will design and engineer more robust, customisable, scalable, and economical cell culture platforms able to optimally manufacture bespoke and complex 3D tissues for future agricultural, pharmaceutical, or medical products.Read moreRead less

Whereas current approaches are limited to defining the external geometry, this technology will permit the organization of the internal structure as well, with the potential to do so at the scale of individual cells. Achieving this has important applications in bioprinting human tissues and additive manufacturing. This is based on the manipulation of particles and cells using holographic acoustic fields controlled by patterned light. This is compared to current acoustic patterning approaches are mostly limited to static simple geometric arrangements and lack the flexibility to produce arbitrary, rapidly changing fields that enable the fabrication of complex structures.
