The Laboratory of Microfluidic Technologies for Biomedicine is developing projects related to the use of microfluidic organ-on-a-chip models of various human organs, both in normal and pathological conditions, studying intercellular interactions, the pharmacokinetics and pharmacodynamics of various drugs and chemicals in preclinical experiments.

The laboratory has unique equipment based on microfluidic technologies, developed by the laboratory head, Prof. Alexander Tonevitsky, including Homunculus microbioreactors, precision microfluidic pumps, microfluidic cell chips, systems for impedance spectroscopy.

Laboratory staff conducted several studies using intestine-on-a-chip (absorption of drugs, dietary supplements, and toxins, secretion and uptake of microRNAs, the role of extracellular matrix and microcirculation in intestinal models, interaction with microbiome), placenta-on-a-chip (placental transport and toxicity of drugs, imitation of hypoxia in the placenta model, the role of miRNAs and extracellular matrix in intercellular interactions), liver-on-a-chip (metabolism and toxicity of different compounds), the blood-brain barrier-on-a-chip (studying the permeability of neurospheres coated with endothelium for various drugs, studying the effects of hypoxia in this model), tumor-on-a-chip/cancer-on-a-chip (growing tumors in a microfluidic device from primary patient cells, analysis of the sensitivity of tumors to drugs, the study of the processes of invasion and metastasis of tumor cells and penetration into target organs within the microfluidic chip), etc. Several studies have shown the role of various laminins as an extracellular matrix in the manifestation of cell and tumor properties, including morphological properties, proliferative, invasive and migratory activity, sensitivity to chemotherapy, etc.

The laboratory has a wide range of partners, both at the Institute and beyond. Together with other laboratories of the Institute, research is being carried out as part of the State task "Microfluidic technologies for the search of physiologically active metabolites, microbiotic agents, and the diagnosis of autoimmune and oncological diseases."

Also, the Laboratory collaborates with the Federal State Budgetary Institution Scientific Research Center for Radiology of the Russian Ministry of Health, the National Research University Higher School of Economics, the Lomonosov Moscow State University, the BioClinicum Scientific and Technical Center, the Technical University of Berlin (Germany), the University Medical Center Hamburg-Eppendorf (Germany), German Cancer Research Center (Germany), art photonics GmbH (Germany), TissUse GmbH (Germany), the University of Manchester (Great Britain), the University of Bern (Switzerland), the Odense University Hospital (Denmark), the Danish Fundamental Metrology A/S (Denmark), Bacalert Ivs (Denmark) and others.

- Microfluidic technologies and organ-on-a-chip modeling for scientific and preclinical studies.
- Studying the role of toxins, including viscumin and ricin.
- The study of the role of microRNAs and their maturation system in the functioning of cells and intercellular interaction, the role of the miRNAs in the development of pathological conditions, as well as their utility as markers of diseases and predictors of various cell and tumor properties.
- Study of the role of the extracellular matrix, in particular various laminins, in determining the properties of tumor cells, including proliferation, invasion, migration, sensitivity to chemotherapy, etc.
