Advances in Bioengineering
Bridget Kendall talks to three pioneers who are pushing the boundaries of bioengineering: John A. Rogers, Magnus Berggren and Hadyn Parry.
Bridget Kendall talks to three pioneers who are pushing the boundaries of what is possible at the interface between engineering, biology and medicine: John Rogers makes electronics which dissolve when they have done their job, Magnus Berggren grows circuits inside plants and Hadyn Parry is using a harmless protein to wipe out dangerous disease carriers.

John Rogers
John Rogers, professor of Materials Science and Engineering at the University of Illinois, designs flexible diagnostic tools which can be implanted in your body and harmlessly bio-degrade once they’ve stopped being useful. His key discovery is that silicon, the workhorse of consumer electronics, does actually dissolve in water when it’s made into nano-scale thin wafers.
Magnus Berggren
Magnus Berggren’s lab for Organic Electronics at Linköping University is bridging the boundary between living and non-living things in another way: they have grown electronic circuits inside a common garden rose. What’s more, they have been able to give the circuits rudimentary switching capacity, opening the door to a direct electrical interface between us and plants.
Hadyn Parry
Hadyn Parry is CEO of a leading UK biotech company which is reducing the numbers of some of the nastiest disease carriers – mosquitoes – with the help of clever genetic manipulation. Unlike most other GM techniques, Oxitec’s self-limiting gene naturally vanishes from the ecosystem after one generation thus giving us the opportunity to stop releasing GM mosquitoes at any point and restore the location to its pre-release state.

Do you think political or business leaders need to be charismatic? Or do you prefer highly competent but somewhat stern people?
