A clever series of scientific portraits has been created using the bacteria of the celebrities they depict.

As part of a science experiment to promote The Big Bang UK Young Scientists & Engineers Fair, Carol Vorderman, Stephen Fry, Dick and Dom, Liz Bonnin and Kieron Richardson each gave a sample of their bacteria, which was then used to create a "bacteriograph" of each celebrity.

The portraits, grown by American microbiologist and photographer Zachary Copfer, were created by exposing select areas of a petri dish to radiation, which encourages the bacteria to grow. Each portrait took around 48 hours to appear.

All six of the portraits will star in a free The Big Bang Fair exhibition from 15 February to 24 February at Millennium Point in Birmingham, before travelling to The NEC in Birmingham for The Big Bang Fair itself from 13 to 16 March.
