Tekniken som varnar för vinterkräksjukan

Av Lukas Nuomit - 29 december 2010 00:17

Vintern är inte bara juletider, nyårsfirande och skidåkning. Varje år drabbas tusentals svenskar av oerhört smittsamma vinterkräksjukan. Forskare på avdelningen mikrosystemteknik på KTH arbetar på en lösning som kan varna människor för platser där vinterkräksjukan sprids.

– Testet skulle exempelvis kunna göras på ett sjukhus. Personalen kan då snabbt vidta åtgärder för att begränsa spridningen och förhindra ett större utbrott. Annars tvingas man stänga flera avdelningar och det blir kostsamt eftersom sjukhuset då inte kan fungera som vanligt, förklarar Niklas Sandström, en av forskarna i projektet.

I spårningsutrustningen sitter en sensor som väger ett nanogram med antikroppar som attraherar uppladdade viruspartiklar som finns i luften. Antikropparna har en förmåga att fånga in och hålla fast viruset, medan övriga partiklar sorteras bort. På bara några minuter kan man avgöra om det rör sig om vinterkräksjukan.

Än så länge kan forskarna samla in viruspartiklar från luften i ett rum men snart hoppas de även kunna spåra viruset direkt till en person via utandningsluften.

Metoden skulle i framtiden även kunna användas för att spåra andra luftburna virussjukdomar, exempelvis svininfluensan.
