In this episode of the A-Z of Tech, we explore the tiny world of nanotechnology and find out about desert ice, the hidden properties of sunscreen and using DNA for storing old lecture notes. 

Our guests this month are Katie King, a Nanotech PhD Student at the University of Cambridge, and Tarik Moussa, from PwC’s innovation and sustainability team. With our hosts Shreya and Louise they discuss some of the extraordinary opportunities nanotech presents for science and business, particularly in the fields of medicine and sustainable technology.
