SERS-based sensor for detection of low levels of Oncogenic proteins in biological

Purpose and goal

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.

Expected results and effects

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.

Planned approach and implementation

The project was developed to study a novel technology platform based on SERS with potential impact towards diagnosis in medicine. Thus work was implemented concerning the following aspects: i) achieving access to clinically relevant samples and benchmarking their detection with existing platforms (flow cytometry). ii) Development of nanoparticle materials for SERS-based detection. iii) Risk assessment in the form of detailed biocompatibility analysis of the nanoparticles used for SERS
