Scientists make world’s tiniest band-aid
(PRESS TV) Japanese researchers make use of nanotechnology to develop the world’s thinnest band-aid which has surgical purposes.
Nano Bansoko (nano band-aid) is made from chitosan — a substance derived from chitin found in crab shells and used for artificial skin — and alginate sodium, produced in kelp slime.
The new adhesive bandage, reported to be a thousand times thinner than plastic wrap, can effectively treat injuries to soft organs such as the lungs. It breaks down naturally after healing and becomes invisible within one month.
Unlike traditional medical adhesives, the use of Nano Bansoko is not associated with an increased risk of adhesion to other tissues, requiring subsequent surgery.
The adhesive properties of Nano Bansoko are reported to increase as the band loses its thickness to values lower than 200 nanometers.
Waseda University researchers concluded that the new bandage is not only as strong as existing adhesives but also lowers tissue adhesion complications.
“We will now conduct a detailed safety evaluation in order to put the bandage into practical use in three years,” said Shinji Takeoka, a polymer chemistry professor.
He added that evaluating the applications of the sheet on other organs like the intestines, and its use in scar prevention on sutured wounds after breast cancer surgeries is the next step.
