Bioinks that Advance 3D bioprinting of cells to the 4th dimension. The aim of this research is to provide a simple method for creating complex 3D cell cultures for in vitro cell based assays using 3D printing. A versatile polymer system as a bioink made from entirely commercially available components, will be advanced that gives a full range of soft tissue mimics and which can be dynamically change on-demand after printing of the 3D cell cultures. The latter will provide in vitro mimics of in vi ....Bioinks that Advance 3D bioprinting of cells to the 4th dimension. The aim of this research is to provide a simple method for creating complex 3D cell cultures for in vitro cell based assays using 3D printing. A versatile polymer system as a bioink made from entirely commercially available components, will be advanced that gives a full range of soft tissue mimics and which can be dynamically change on-demand after printing of the 3D cell cultures. The latter will provide in vitro mimics of in vivo events never previously possible with more realistic models of what is found in vivo. Applications are in fundamental cell biology, studying diseases and developing new drugs. The outcomes from this research will be new knowledge on designing cheap extracellular matrix mimics and high throughout 3D cell assays.Read moreRead less

Summary
Bioinspired liposome-based smart sensors. This project aims to develop a liposome-based biosensor technology that mimics cell sensory systems. Selective detection of compounds is increasingly important for food, health and environmental monitoring. Biosensor development faces long-standing challenges such as response time, sensitivity, specificity, and multiplexing. On the other hand, cells can sense and discriminate multiple biomolecules in seconds with high sensitivity and specificity. This pr ....Bioinspired liposome-based smart sensors. This project aims to develop a liposome-based biosensor technology that mimics cell sensory systems. Selective detection of compounds is increasingly important for food, health and environmental monitoring. Biosensor development faces long-standing challenges such as response time, sensitivity, specificity, and multiplexing. On the other hand, cells can sense and discriminate multiple biomolecules in seconds with high sensitivity and specificity. This project aims to harness cells’ exquisite biological properties to improve current detection techniques. It will integrate liposome-based sensors with microfluidics to perform analytical tasks ranging from food safety to diagnostics.Read moreRead less
Harnessing the bioactivity of proteins and polypeptides: understanding and controlling adsorption processes to optimise linker free immobilisation. This project will use physical techniques and simulations to understand the interactions of biomolecules and plasma activated surfaces, allowing control of the biomolecule layer composition, orientation and conformation. This control, together with the ability of these surfaces to "lock-in" the optimised layer, will create a new generation of biodevi ....Harnessing the bioactivity of proteins and polypeptides: understanding and controlling adsorption processes to optimise linker free immobilisation.

Biofabricated tissue mimics for nanoparticle design and development. Nanoparticles are widely used in commercial applications spanning biotechnology, health and environmental monitoring, and drug delivery. Materials scientists can generate large libraries of nanoparticles, but the toolbox available to test these nanoparticles is limited. We will use biofabrication to comprehensively evaluate the fate of polymer grafted nanocellulose across simulated tissue barriers. Model blood vessels with reci ....Biofabricated tissue mimics for nanoparticle design and development. Nanoparticles are widely used in commercial applications spanning biotechnology, health and environmental monitoring, and drug delivery. Materials scientists can generate large libraries of nanoparticles, but the toolbox available to test these nanoparticles is limited. We will use biofabrication to comprehensively evaluate the fate of polymer grafted nanocellulose across simulated tissue barriers. Model blood vessels with recirculating flow will help understand permeation; tunable matrices will establish ‘matrix structure—nanoparticle diffusion’ criteria. The outcome from this project will be an understanding of how plastic nanoparticles penetrate tissue, to guide nanomaterials design and mitigate risk associated with toxicity. Read moreRead less
