SERS-baserad sensor för detektion av låga nivåer av onkogena proteiner i biologiska prover

Syfte och mål

A senor technology platform using a nanotechnology-based approach aiming at molecular detection of relevant biomedical markers in the medical field was to be developed in the form of SERS-based sensors for monitoring low levels of biomolecules. Feasibility of this platform towards future application was to be tested, involving also a risk analysis concerning biocompatibility. The project was also supposed to allow the VINMER fellow to gain experience towards a future career as group leader.

Resultat och förväntade effekter

The following key scientific milestones were achieved: i) Synthesis of nanoparticles for SERS and demonstration of the working principle. ii) Detailed biocompatibility study of the nanoparticles used for SERS, in particular concerning their interaction with cells. iii) Complementary high-throughput detection of biomolecules in clinical samples with fluorescence as comparative method. The VINMER fellow achieved important skills towards pursuing a careers as independent group leader.

Upplägg och genomförande
