Label-free single-molecule detection of complex biomolecule interactions in free motion

Project description

Label-free imaging of biomolecular interactions

Dysregulated interactions between biomolecules drive abnormal cell signalling and gene expression, leading to many human diseases. Understanding these interactions in real time is essential for discovering effective therapies. However, existing techniques often require labels or immobilisation that distort the natural behaviour of molecules. With the support of the Marie Skłodowska-Curie Actions programme, the LABIMO project will develop a new optical microscopy tool to directly observe interactions between individual biomolecules at the single-molecule level. The method will work without labels and will accommodate molecules that differ widely in size, weight and physical properties. By capturing dynamic interactions as they occur, the technology will open access to biological systems previously difficult to study.

Objective

Dysregulated interactions between biomolecules can lead to changes in cell signalling and gene expression, both common drivers of human disease. A detailed understanding of these interactions is vital for drug development, often targeting such interactions for therapeutic effects. In this project, I aim to develop an optical microscopy tool to observe interactions of highly diverse biomolecules in terms of e.g. weight or size, in real-time on a single-molecule level without the use of labels or immobilization, which limits many current established methods. This will allow the study of dynamic interactions between complex biomolecules of varying sizes and with a wide range of properties. The tool will be capable of researching various biological systems that are not easily accessible by established methods. This could contribute to breakthroughs in the research of severe diseases such as diabetes mellitus, Alzheimer's, or Parkinson's disease.
