Starting from basic concepts of liquid crystalline phases, I will first introduce two experimental studies on the self-organised structures of rod-like viruses and single DNA chains: their morphogenesis, growth kinetics, topological defects, coil-globule transition, etc. In the next part, it will be presented how 3D random networks of biopolymers can be utilised as drug delivery platforms and stem cell niches. Then, I will close the talk by briefly mentioning the current work on cell-laden microgels coupled with droplet microfluidics.
