Aceast\u0103 descoperire ar putea contribui la reducerea r\u0103sp\u00e2ndirii bolilor prin intermediul obiectelor atinse frecvent, precum smartphone-urile, tastaturile \u0219i echipamentele medicale.<\/p>\n

Pe l\u00e2ng\u0103 eficacitatea sa, materialul este conceput s\u0103 fie practic pentru utilizarea \u00een via\u021ba de zi cu zi, potrivit ScienceDaily<\/a>.<\/p>\n

Spre deosebire de suprafe\u021bele antivirale anterioare, realizate din metale sau siliciu, aceast\u0103 nou\u0103 abordare utilizeaz\u0103 plastic flexibil care poate fi produs la scar\u0103 larg\u0103.<\/p>\n

Cum distrug nanopilonii viru\u0219ii<\/h2>\n

Folia este fabricat\u0103 din acril \u0219i acoperit\u0103 cu structuri extrem de mici, cunoscute sub numele de nanopiloni. Aceste elemente minuscule se aga\u021b\u0103 de virus \u0219i \u00eei \u00eentind stratul exterior p\u00e2n\u0103 c\u00e2nd acesta se rupe.<\/p>\n

\u00cen loc s\u0103 se bazeze pe dezinfectan\u021bi chimici, suprafa\u021ba folose\u0219te for\u021ba mecanic\u0103 pentru a neutraliza virusul.<\/p>\n

Cercet\u0103rile au descoperit c\u0103 aceast\u0103 metod\u0103 de \u00eentindere este mai eficient\u0103 dec\u00e2t modelele anterioare care \u00eencercau s\u0103 perforare viru\u0219ii.<\/p>\n

Testele de laborator arat\u0103 o inactivare puternic\u0103 a virusului<\/h2>\n

\u00cen experimentele care au utilizat virusul parainfluenza uman 3 (hPIV-3), care provoac\u0103 bron\u0219iolit\u0103 \u0219i pneumonie, rezultatele au fost uimitoare.<\/p>\n

\u00cen decurs de o or\u0103 de la contact, aproximativ 94% din particulele virale au fost fie distruse, fie deteriorate at\u00e2t de grav \u00eenc\u00e2t nu mai puteau s\u0103 se reproduc\u0103 \u0219i s\u0103 provoace infec\u021bii.<\/p>\n

Echipa a utilizat \u00een mod inten\u021bionat materiale ieftine, care pot fi fabricate cu u\u0219urin\u021b\u0103.<\/p>\n

O regul\u0103 simpl\u0103 de proiectare pentru suprafe\u021bele care distrug viru\u0219ii<\/h2>\n

Lucr\u0103ri anterioare privind materialele rigide, precum siliciul cu nanospi\u021bi, au ar\u0103tat c\u0103 viru\u0219ii pot fi distru\u0219i fizic.<\/p>\n

Acest studiu dezvolt\u0103 aceast\u0103 idee, demonstr\u00e2nd c\u0103 at\u00e2t elementele ascu\u021bite, c\u00e2t \u0219i cele rotunjite la scar\u0103 nanometric\u0103 pot fi eficiente atunci c\u00e2nd sunt dispuse corect.<\/p>\n

Rezultatele sugereaz\u0103 un principiu clar de proiectare: cu c\u00e2t nanostructurile, precum spinii sau nanopilonii, sunt mai apropiate unele de altele, cu at\u00e2t sunt mai eficiente \u00een distrugerea viru\u0219ilor.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 doresc, de asemenea, s\u0103 examineze c\u00e2t de bine func\u021bioneaz\u0103 pelicula texturat\u0103 pe suprafe\u021be curbate, deoarece curbura poate modifica distan\u021ba dintre nanopiloni.<\/p>\n","protected":false},"excerpt":{"rendered":"
