Recently there has been an increasing interest in the coupling of biocatalytic or bio-based feedback with materials, inspired by emergent behavior in natural systems. Here we discuss our efforts in the exploitation of enzyme-catalyzed reactions that display switches in pH to create time-lapse polymerisation or hydrogels; “cure-on-demand” constant speed gel fronts and timed gel degradation. We show how enzymes can be used for ultrasensitive sensing when encapsulated in gel beads or vesicles and for self-organization in mineral formation. These bioinspired processes may provide insights into behaviour in cellular systems such as bacteria as well as new methods for drug delivery, sensing and repair that can be exploited in living systems.

About The Speaker


Dr Annette Taylor is Senior Lecturer in Chemical and Biological Engineering at the University of Sheffield. She obtained a PhD in Physical Chemistry from the University of Leeds and was later RCUK Fellow then Senior Lecturer at Leeds, and Visiting Professor at the University of West Virginia and Lousianna State University. She moved to Sheffield in 2014 to pursue applications in reaction engineering, with particular interest in the design and optimisation of autocatalytic reaction networks in non-equilibrium materials, devices or sensors.
