Natural melanin is formed by the specific enzymatic reaction of tyrosine in the presence of tyrosinase,and the formed melanin can induce fluorescence quenching via photo-induced electron transfer(PIET)process between melanin and fluorescent materials.Based on this,various melanin/PDA-based biosensors are synthesized by simulating the formation process of melanin.As summarized in Table 3,melanin/PDA-based biosensors are widely used for the detection of biomarkers and cell microenvironment.Moreover,due to the high metal ions chelating capacity,melanin/PDA-based biosensors can also be used for the detection of metal ions with high sensitivity and selectivity.
