Young Elite-Researcher's Award DIPLOMA

Alexandra Boltasseva receives the Danish Independent Research Councils' Young Elite-Researcher's Award (Ung Eliteforskerpris) for the recently granted Research Project "On-Chip Nano-Imaging Using Superlens (NanoMIUS)" (2007-2010).

The "Elite-Researcher" initiative's goal is to add visibility and to reward some of the best young researchers. Every year, the Danish Independent Research Councils' awards go to about 20 young researchers from all fields (ranging from social sciences and humanities to natural sciences and engineering). Alexandra Boltasseva got the Danish Independent Research Councils' Young Researchers Award (Ung Eliteforskerpris).

Pressemeddelelse 21. November 2007 Forsknings- og Innovationsstyrelsen (in Danish)

Fri forskning giver plads til de gode ideer.

En effektiv og billig vaccine mod hvepseallergi og en superlinse, der kan "se" processerne i levende celler. Dét er perspektiverne i to af de projekter, som Forskningsrådet for Teknologi og Produktion har støttet i 2007.

Eksemplerne viser, at Forskningsrådet for Teknologi og Produktions bevillinger gør en forskel: Forskerne får øje på en udfordring og en problemstilling og med deres ekspertise kommer de med nye og anderledes bud på en løsning.

Der er dog altid en risiko for, at projekterne ikke fører til de ønskede resultater. "Sådan er forskningens vilkår. Omvendt - når det lykkes - står vi måske med et forskningsmæssigt gennembrud," siger professor, Marcel A. J. Somers, formand for Forskningsrådet for Teknologi og Produktion (FTP).

Havde de to projekter ikke fået støtte fra FTP, var de nok ikke kommet i gang, forklarer FTP's formand. Den type forskning har svæyrt ved at finde finansiering. Som de øvrige fire råd under Det Frie Forskningsråd stiller FTP nemlig ikke krav om, at forskningen skal ligge inden for strategisk fastlagte forskningsomrder. Forskningen støttes alene, fordi den er nyskabende og i international topklasse.

En af to eksempler på forskningsprojekter, der har fået støtte fra FTP:

Superlinse kan hjælpe til bivirkningsfri medicin
Hidtil har man ikke kunnet fotografere celleprocesser uden at gribe ind i dem. Men med en superlinse, der kan afbilde celleprocesserne uden indgriben, vil man f.eks. kunne afdække, hvordan processerne i syge celler adskiller sig fra raske eller se, hvordan medicin påvirker cellen. Dermed kan man udvikle medicin, som er målrettet de syge celler og derfor uden bivirkninger.

Superlinse, der kan "se" processerne i levende celler
I de seneste år er det lykkedes forskere at udvikle særlige optiske teknikker, så man kan afbilde proteiner, enzymer og andre nano-små molekyler - i størrelsesordenen 5-10 milliontedele millimeter.

I dag kan det imidlertid kun lade sig gøre ved at anbringe linsen - en optisk fiber - så tæt på objektet, at den næsten rører ved det. Det betyder for eksempel, at man er nødt til at trænge ind i en celle, hvis man vil fotografere, hvad der foregår inde i den. Man forstyrrer dermed cellen og kan med andre ord ikke optage en realistisk "film" af processerne inde i en levende celle.

Men ny viden tyder på, at det er muligt at udvikle en superlinse, som kan afbilde detaljer i en celles indre, selvom linsen placeres uden for cellen og ikke rører ved denne - og altså ikke forstyrrer celleprocesserne.

FTP har derfor givet en bevilling på 4,2 mio. kr. til adjunkt, ph.d. Alexandra Boltasseva, som vil udforske mulighederne for at udvikle en sådan superlinse.

Hvis det lykkes, vil man for første gang nogensinde kunne se, hvad der reelt foregår på nanoskopisk niveau i en levende celle. Dét kan for eksempel bruges til at afdække, hvordan processerne i syge celler adskiller sig fra de raske. Eller til at identificere præcist, hvad der sker, når medicin påvirker cellen. Det giver et enestående grundlag for at udvikle medicin, der er præcist målrettet mod de syge processer - altså effektiv medicin uden bivirkninger.
