Priscila Monteiro Kosaka holds a degree in chemistry from the University of Brasília (UnB, Brazil) and a PhD in chemical-physics from the University of São Paulo (USP, Brazil). During her doctoral thesis, she acquired an in-depth knowledge of the chemistry of surfaces. She has been a member of the Bionanomechanics Lab at the Institute of Micro and Nanotechnology of Madrid (CSIC) since 2008, where she supervises activities related to the functionalisation of surfaces. Her main interest is to develop ultra-sensitive diagnostic tools for the early detection of cancer by fusing nanomechanical systems with other promising nanotechnologies, in particular nano-optics. Project evaluator at the European Commission, editorial member of the journal Translational Materials Science, guest editor of a special issue of the journal “Sensors” (Elsevier), and member of the scientific advisory board of the company Mecwins. ComFuturo Researcher (I edition) in the line of research of the programme “New technologies for early cancer detection“. She developed, in the Institute of Micro and Nanotechnology of CSIC, her project “Ultrasensitive nano-sensor for the early detection of breast cancer in blood”.
Tumours secrete proteins known as tumour-specific circulating proteins (TCPs) into the bloodstream that signal disease initiation. The detection of TCPs (concentration during malignant growth ≤ femtomolar) promises to revolutionise cancer treatment, enabling the early detection of the disease. However, there is currently no technology capable of “finding” TCPs at ultra-low concentrations and coexisting with more than 103 different proteins, some of them at concentrations 12 orders of magnitude higher, in the same sample.
This project aims to develop a simple and affordable blood test for the detection of TCP in breast cancer patients. It is intended to:
- i) develop a high-throughput technology for the identification and quantification in a wide dynamic range of biomarkers with a low error rate, and
- ii) apply this technology in clinical trials and formulate a list of potential biomarkers for the early detection of breast cancer in blood.
Breast cancer is the most common type of cancer and the leading cause of cancer death among women in industrialised countries. Thus, given the considerable public health importance of breast cancer, it is crucial to be able to rapidly identify TCPs with the potential to improve the early diagnosis, which could save one million lives worldwide each year.
The aim is to develop an ultrasensitive and specific sensor for the detection of proteins related to the onset of breast cancer tumour development with a simple blood test. This technology for rapid and early detection of cancer does not yet exist and will undoubtedly have a high impact on patient survival. Subsequently, it will be extrapolated to other types of tumours.
