Chemist Jan Enberts of the University of Groningen in the Netherlands is more cautious.
"It's still a totally open question," he
says."To say the phenomenon has biological significance is pure speculation."But he
has no doubt Samal and Geckeler have discovered something new."It's surprising and worrying," he
The two chemists were at pains to double-check their astonishing results.Initially they had used the scattering of a laser to reveal the size and distribution of the dissolved particles.To check, they used a scanning electron microscope to photograph films of the solutions spread over slides.This, too, showed that dissolved substances cluster together as dilution increased.
