Bioglass can heal our bones while fending off harmful microbes
Bioglass can heal our bones while fending off harmful microbes

From windows and bottles, to optical fibres and solar cells, glass is an incredibly versatile material that underpins many technologies. In the June episode of the Physics World Stories podcast, Andrew Glester explores a lesser known application of glass – bioglass in healthcare.

First you will hear from Julian Jones at Imperial College London, who explains how glass putty can help to heal broken bones by stimulating tissue growth. Jones has previously worked with the inventor of bioglass, Larry Hench, a materials engineer whose 1969 breakthrough was inspired by a chance conversation with an army major recently returned from the Vietnam War. Jones is currently developing “bouncy bioglass” that can stimulate bone growth while simultaneously sharing the load placed on bones – making it particularly useful for bad traumas where bones struggle to re-join.

Later in the episode, Glester is joined by Martyna Michalska, a nanotechnology researcher at University College London. As part of her research, Michalska designs glass surfaces patterned with nanoscale features that can be tuned to resist unwanted bacteria. In hospital settings, surfaces could be fitted with the technology as an alternative to chemicals that bacteria can evolve to resist. Michalska is working with industrial partners and they are looking at the option of retrofitting windows and other surfaces with thin films of her nanopatterned glass.

To learn more about glass-based technologies, take a look at the June issue of physicsworld-iop.content.pugpig.com/blog/2022/05/23/highlights-98/pugpig_index.html">Physics World, a special issue inspired by the International Year of Glass (IYOG2022).
