The rapid emergence of new illegal drugs (HHC, nitazenes, synthetic cathinones, etc.) creates a need for fast, on-site drug testing tools that can detect multiple substances in biofluids. These tools are crucial for clinicians, anti-doping experts, and law enforcement. Multiplexed portable analytical tools have a great potential to be implemented for this purposes. Moreover, such kind of instruments could be utilized in personal healthcare monitoring by enabling early-stage diagnostics of health problems. This project aims to develop electrophoresis-based analytical tools for reliable, fast and cost-effective metabolism studies in vitro, revealing the characteristics and metabolic pathways of new psychoactive substances. Additionally, new on-site biofluid testing tools (focused on oral fluid) will be developed for detecting new drugs. The results of this project will enhance drug monitoring, support public health, and improve safety.

This study aims to explore the chemical composition and variability of Estonian bee pollen across different seasons and potentially different regions. The focus is on analyzing the content of various bioactive compounds, such as antioxidants, amino acids, and volatile compounds, to evaluate the nutritional value and potential of pollen as a functional food.
