Laboratory of Optics and Dynamics of Biological Systems 鈥� 91视频

The laboratory conducts research in the field of biophotonics, which involves the interaction of electromagnetic radiation (primarily in the optical range) with biological objects. We strive to understand biological processes based on predictive physical descriptions. This enables the development of methods for characterizing and effectively managing systems, including applications in medical diagnostics and interventions. The laboratory is developing methods for using photoswitchable molecules to generate bio-specific compounds and activate cellular responses with high spatial and temporal precision.

Current Research Directions

1. Platelet Activation Studies Investigating platelet activation in response to various stimuli is a key area of research in hemostasis and vascular biology. We develop and apply photolabile ("caged") compounds to study the dynamics of cellular reactions. - One example is the study of platelet activation. To analyze this process in detail under laboratory conditions, it is necessary to trigger activation with high temporal and spatial precision. We have developed a technology for initiating platelet activation using optical pulses and photolabile activation agonists.
- Another example is improving the properties of drugs for treating coronavirus infections using photolabile groups that facilitate drug penetration into cells. We employ mathematical modeling to gain deeper insights into biological processes, ranging from cytoskeletal mechanics to light scattering by cells. Additionally, we are developing photoactivatable nitric oxide donors, which have potential applications in medicine, such as treating diabetes-related complications. However, since nitric oxide is a common mediator in biology, our developments can be applied in many areas of scientific research.
2. Development of Optical Monitoring Devices The laboratory has developed several modifications of a device capable of tracking dynamic changes in various systems (including cellular systems) based on light scattering variations (Litunenko, 2023). The device has been tested on a range of cell models, including *E. coli*, HEK293, and NALM cells. Preliminary results have been presented at conferences such as BGRS/SB-2024 (Novosibirsk, Russia), ALT'24 (Vladivostok, Russia), and the "Nasha Laba" project (2024, Moscow, Russia).
