In this study, we utilised hex-star phosphorene as the main detecting material to identify the nucleobases. Nucleobases, being crucial carriers of hereditary information are identified through specific hydrogen bonding and steric interactions such as adenine pairing with thymine (or) uracil and guanine pairing with cytosine. The stable hex-star phosphorene possesses negative formation energy of -5.194 eV. The hex-star phosphorene exhibits a semiconductor nature with an energy band gap of 1.658 eV, which is deployed as the adsorbing substrate for nucleobases. Based on the Mulliken charge analysis, adsorption energy, relative band gap variation, and the detection efficiency of hex-star phosphorene towards nucleobases are examined. The outcome confirms the physisorption of nucleobases on hex-star phosphorene and strongly supports that hex-star phosphorene can be used as sequencing material for DNA and RNA., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Amino acids are required to make protein. The deficiency of amino acids leads to a lack of sleep and mood. Among various amino acids, we conducted the adsorption studies of alanine and asparagine amino acids on a novel one-dimensional material, chair graphene nanotube. The stability of the chair graphene nanotube is ensured with the negative formation energy, which is -6.490 eV/atom. The energy band gap of bare chair graphene nanotube is 1.022 eV, which possesses a semiconductor nature. The stable chair graphene nanotube is used as adsorbing material for alanine and asparagine amino acids. Besides, alanine and asparagine are physisorbed on chair graphene nanotubes that are confirmed by the range of adsorption energy from -0.107 eV to -0.718 eV. Upon adsorption of amino acids, the charge transfer outcome shows that chair graphene nanotubes behave as donors of electrons to alanine and asparagine. Further, the changes in the band gap of the chair graphene nanotube are noticed from the results of band structure and PDOS spectrum.
