Scientific interests
- Design, synthesis and application of peptides/lipopeptides immobilised on solid supports as useful tools for medical diagnostics
Various molecular approaches and tools are being used in research to develop methods useful for the rapid, sensitive diagnosis of oncological, autoimmune and neurodegenerative diseases. One of these is molecular receptors and peptides immobilised on cellulose allowing specific binding of potential biomarkers (low molecular weight, polypeptide, protein) of a given disease present in physiological fluids (urine, blood, cerebrospinal fluid, tissue homogenates). The developed solution has found application in the search for diagnostic/prognostic biomarkers of cancer (thyroid cancer, C38 colon cancer, 16/C breast cancer, LLC lung cancer), autoimmune diseases (RA rheumatoid arthritis, arteriosclerosis), neurodegenerative diseases (Parkinson’s, Alzheimer’s diseases) and coronary heart disease.
- Design and synthesis of nanoparticle conjugates – new therapeutic approaches
Nanomaterials are widely used in medicine. Our research focuses on the development of new methods for the functionalisation of nanomaterials, allowing conjugates with significantly improved application properties to be obtained. The research is focused on the creation of derivatives containing a therapeutic fragment attached to the nanoparticle, as well as structural fragments that improve selectivity in reaching pathological sites and improve permeation through cell membranes. Conjugates of nanomaterials with a drug and a homing fragment can be used in cancer therapy. If magnetic nanoparticles are used, they can also be used as materials in thermoablation.
