Hi Reddit, we are Hannah and Xiang from the Materials for Health Lab at the University of Bath.
I (Hannah) lead the lab in creating new materials for devices that can be used to detect diseases such as bacterial infections and making materials for smart wound dressings (so we can monitor how the wound is healing).
I (Xiang) am a postdoc in the lab and with iCAST (the Innovation Centre for Sustainable Technologies), I use electrospinning to make new materials. Electrospinning is a technique where we apply a very high voltage across a small needle full of polymer, which makes lots of nanofibers, (very, very tiny fibres).
So, why do we need these new materials? While there are lots of devices and materials that have transformed healthcare, we need to ensure these are made using sustainable processes and sources so we can provide accessible healthcare to everyone. For example, by printing microneedle devices using lab-bench 3D printers, we can, in principle, make them anywhere for everyone.
We’d love to answer any questions on how we do this, specifically using microneedles, 3D printing, electrospinning, and how these can support a sustainable healthcare system. Please Ask Me Anything!
We’ll be online to answer questions on Friday 13 October from 2.30 - 3.30pm BST.
