SESBL research area is at the interface of analytical chemistry, physics (plasmonic) and biology. We explore surface enhances spectroscopies such as Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Fluorescence (SEF) in sensing applications, including detection of biomarkers. There are serval directions of research: SERS sandwich immunoassays of biomarkers on non traditional substrates, SEF of cells modified with quantum dots on various substrates, detection of high protein content in urine by SERS and Raman spectroscopy as well as study of SERS fundamentals: relationship between enhancement and structure of nanoaggregates. We got experience not only in publishing papers based on our own experimental results but also in writing and publishing review papers on topics related to analytical chemistry in such journals as Talanta, Sensing and Biosensing research, Analytical Methods. Our group currently includes 2 - 3 Research assistants , one master degree student, who started to work in the group as undergraduate 2nd year student and who already co-authored 5 paper, including 3 Q1 papers, and several undergraduate students.
