摘要：Current development of miniature analytical instruments for detecting heavy metals in varying samples is very dynamic. One of the most interesting representatives of these instruments are biosensors, which combine the physico-chemical transducer with biological components. Biosensors can operate on different principles and their preparation can lead to the acquisition of tools, which can achieve high sensitivity and selectivity against individual heavy metal ions or their mixtures. Our paper discusses the various types of biosensors divided according to their biological components for the detection of heavy metals ions
