• FETs lack responsivity and selectivity for its detection due to the presence of interfering compounds such as uric acid (UA). Surface modification of CNTs using single-stranded deoxyribonucleic acid (ssDNA) renders the surface responsive to DA and screens the interferent. Due to the presence of

• : carbon nanotube; deoxyribonucleic acid; dopamine; field-effect transistor; uric acid; Introduction Single-walled carbon nanotubes (SWCNTs) are excellent chemical/biological sensing materials because of their ultra-high sensitivity, fast response, and size compatibility, as compared to traditional

• affinity and specificity of molecular recognition, whereas an electronic route promises faster detection [8][9]. In particular, single-stranded deoxyribonucleic acid (ssDNA) decoration on SWCNT has garnered tremendous attention because of its selectivity and sensitivity towards a wide range of analytes
