In the reported work, we have approached the interaction of the amino acids to the Sb monolayer by using density functional theory (DFT). Here, we have considered glycine (Gly), glutamic (Glu), histidine (HIE/His) and phenylalanine (Phe) biomolecules for interaction. The structural, electronic optical properties have been investigated to understand the behavior. The adsorption of the biomolecules reported the physisorption process. The adsorption energy of the phenylalanine (Phe) biomolecules is the most favorable. The optical absorption peaks of systems come in the near visible region. The studies conclude that Sb monolayer is useful for the bio-integrated electronics based devices.

在报道的工作中，我们已经通过使用密度泛函理论（DFT）来研究了氨基酸与Sb单层的相互作用。在这里，我们考虑了甘氨酸（Gly），谷氨酸（Glu），组氨酸（HIE / His）和苯丙氨酸（Phe）生物分子之间的相互作用。已经研究了结构，电子光学性质以了解其行为。生物分子的吸附报告了其物理吸附过程。苯丙氨酸（Phe）生物分子的吸附能是最有利的。系统的光吸收峰出现在附近的可见光区域。研究得出结论，锑单层可用于基于生物集成电子学的设备。
