O echipa de specialisti americani a utilizat vata de zahar pentru crearea unei retele de tuburi asemanatoare vaselor sanguine, destinata sa transporte sange prin tesuturile artificiale. Cercetatorii au folosit un fragment de vata de zahar, peste care au turnat un polimer lichid. Dupa solidificarea acestuia, zaharul solubil in apa este indepartat prin spalare, lasand in urma o retea de tuburi foarte fine. Firele de zahar care alcatuiesc vata au acelasi diametru ca si vasele capilare – cele mai subtiri vase de sange dintr-un organism animal. Daca tehnologia va avea succes, acest nou material va putea fi folosit in chirurgie pentru realizarea unor proceduri precum grefele de piele sau reconstructia sanului dupa mastectomie.
