The deamination and decarboxylation of the amino acid – asparagine results in intermediate metabolite – lactate and polyamine – putrescines, which are culpable for the release of malicious odors into the atmosphere. In the present research, the bio-molecules (Asparagine, Lactate, and Putrescine) are taken as primary molecules and are admitted to interact with the two-dimensional nanomaterial – Kagome form of phosphorene nanotube (Kagome-PNT) by employing the density functional theory mode. Besides, the electronic features of the pure Kagome-PNT and bio-molecules interacted Kagome-PNT (complex) are estimated in addition to the COHP analysis on the complexes at the spot of bio-molecule interaction (hollow and triangle-spot). Further, the interaction features namely the binding energy, average energy gap alteration, and Bader charge transfer are gauged so that our recommendation of utilizing Kagome-PNT as a fundamental component in chemi-resistive based detector to sense the existence of bio-molecules (asparagine, lactate, and putrescine) can be confirmed.

氨基酸（天冬酰胺）的脱氨基和脱羧作用产生中间代谢产物（乳酸和多胺）腐胺，可将其释放到大气中。在本研究中，生物分子（天冬酰胺，乳酸和腐胺）被当作主要分子，并通过利用密度泛函理论被承认与二维纳米材料–磷纳米管的Kagome形式（Kagome-PNT）相互作用。模式。此外，除了对生物分子相互作用点（空心和三角形斑点）处的配合物进行COHP分析外，还估算了纯Kagome-PNT和生物分子相互作用的Kagome-PNT（配合物）的电子特征。此外，相互作用的特征是结合能，平均能隙变化，
