Perspective Research Activities at SPbSPU Single-cell biopsy/ Cell-to Cell communication Single-cell biopsy/ Cell-to Cell communication Capsule-Surface interactions Capsule-Surface interactions Fabrication of Release control over depot-systems Fabrication of Release control over depot-systems In vivo studies for encapsulated drugs delivery In vivo studies for encapsulated drugs delivery and more… and more… - BioMedical & BioPhysics

6. Single-cell biopsy / Cell-to-Cell Communication Capturing molecules intracellularly and delivery to other cells – artificial exosomes exchange Available expertise: Mass-Spec, Cell facilities Collaboration: Prof. M.Khodorkovskii Dr. Irina Nazarenko (Freiburg), Dr. Arkady Shipuline

7. Capsule – Surface Interaction - One of major problems of LbL microencapsulation technology – aggregation and sticking to cell membranes when used in vivo. - Some coatings (PLL-g-PEG, Dextran) are proposed to cope with the problem, but are not absolute solution. Study adhesion aiming to optimize selectivity to cell surface Optical tweezers technique (M. Khodorkovski’s group) to measure interaction forces.

8. Fabrication and Release control of depot-systems Fabrication and controlled gradual release from microcapsules and its assemblies as a depot-system. Monitoring on cell culture/ Tissue scaffolds. Modelling of Release kinetics
