Recent advances in the development of portable technologies and commercial products to detect Δ 9 -tetrahydrocannabinol in biofluids: a systematic review.

The foremost challenge in THC detection involves creating electrochemical sensors that are both stable and long-lasting while exhibiting exceptional selectivity, minimal non-specific interactions, and decreased susceptibility to matrix interferences. These aspects need to be resolved before these sensors can be successfully introduced to the market.
