\nInstrumentul util a fost dezvoltat de o echip\u0103 de la Universitatea Normal\u0103 din Shanghai , \u00een colaborare cu profesorul Tony James, chimist de la Universitatea din Bath (Marea Britanie).<\/p>\n
\nSpre deosebire de pulberile d\u0103un\u0103toare sau solven\u0163ii chimici, noul spray este solubil \u00een ap\u0103 \u015fi are o toxicitate sc\u0103zut\u0103, scrie focus.it.<\/p>\n
\nNu interfereaz\u0103 cu ADN-ul \u015fi poate fi utilizat chiar \u015fi pe amprente vechi de o s\u0103pt\u0103m\u00e2n\u0103. Cu toate acestea, coloran\u0163ii noului produs, se bazeaz\u0103 pe un compus fluorescent numit GFP (Green Fluo Protein).<\/p>\n
\nEchipa de cercet\u0103tori \u015fi profesorul britanic sunt siguri c\u0103 inven\u0163ia lor va \u00eembun\u0103t\u0103\u0163i investiga\u0163iile criminalistice, f\u0103c\u00e2ndu-le mai rapide \u015fi mai eficiente.<\/p>\n
\n\u201eSistemul nostru este mai sigur, mai durabil \u015fi func\u0163ioneaz\u0103 mai rapid dec\u00e2t tehnologiile existente\u201d, explic\u0103 prof. James, \u201e\u015ei poate fi folosit chiar \u015fi pe amprentele digitale vechi de o s\u0103pt\u0103m\u00e2n\u0103.\u201d<\/p>\n
\nEchipa de cercetare a creat doi coloran\u0163i diferi\u0163i, numi\u0163i LFP-Yellow \u015fi LFP-Red , practic un spray galben \u015fi unul ro\u015fu pentru a fi folosit \u00een func\u0163ie de culoarea suprafe\u0163ei pe care urmeaz\u0103 s\u0103 fie luat\u0103 amprenta. Odat\u0103 pulverizat, produsul se leag\u0103 de substan\u0163ele chimice din transpira\u0163ie \u015fi uleiurile de piele, f\u0103c\u00e2nd amprentele vizibile sub lumin\u0103 albastr\u0103.<\/p>\n
\nProteina GFP, utilizat\u0103 \u00een spray, este produs\u0103 natural de meduza Aequorea victoria. Este deja folosit\u0103 de zoologi pentru a vizualiza procesele biologice ale celulelor animale.<\/p>\n","protected":false},"excerpt":{"rendered":"
