• electronic platform for biosensing [14]. Previously, numerous works have demonstrated that nucleic acid-functionalized CNT-based FETs exhibit fast, specific, and reproducible response to the detection of various polar molecules [15][16]. Since ssDNA has four bases, it gives the possibility of numerous

• .5.217 Abstract A single-walled carbon nanotube (SWCNT) in a field-effect transistor (FET) configuration provides an ideal electronic path for label-free detection of nucleic acid hybridization. The simultaneous influence of more than one response mechanism in hybridization detection causes a variation

These coordinates were used as templates from which longer fibrils were constructed. The Nucleic Acid Builder (NAB) software

[137] created CNT–PM samples in two steps: first, a nucleic acid grafting at the CNT tips, leading to the opening of their end caps, and then a spin-on-glass deposition inside the VA-CNT array
