Aus­tralian re­searchers in­tro­duce tiny fi­bre op­tic probe

BioSpectrum (Asia) - - SCIENCE NEWS -

A team of re­searchers at the Uni­ver­sity of Ade­laide has in­vented a world-first tiny fi­bre-op­tic probe that can si­mul­ta­ne­ously mea­sure tem­per­a­ture and see deep in­side the body. The minia­turised imag­ing and sens­ing probe has been de­vel­oped to help study drug-in­duced hy­per­ther­mia.

With an outer di­am­e­ter of only 130 mi­crons, the probe is as thin as a sin­gle strand of hu­man hair. The probe may help re­searchers find bet­ter treat­ments to pre­vent drug-in­duced over­heat­ing of the brain, and po­ten­tially re­fine ther­mal treat­ment for can­cers.

While the first gen­er­a­tion of the probe can both take im­ages and mea­sure tem­per­a­ture, the team hopes fu­ture gen­er­a­tions will take other mea­sure­ments as well - such as pH val­ues, oxy­gen sat­u­ra­tion and ac­cu­mu­la­tion of fat in ar­ter­ies.
