The paper presents a brief overview of physical-chemical sensors used for carcinogenic compounds detection in water objects. Particular attention is paid to optical sensors which are based on nanomaterials and called nanophotonic sensors. We describe the principles of operation, construction and application of the proposed nanophotonic sensor for the determination of organic carcinogens such as 3,4-benzo[a]pyrene which is one of the most harmful from PAHs in aqueous solutions. The advantage of device is the simplicity and low cost, express method of analysis, low detection limit. High selectivity and the ability to automate analysis, processing, preservation and storage of the information makes possible its use in the environment, medicine and pharmacy.
