Fig. 4 COHP analysis for pristine
Kagome-PNT.
Now, the primary bio-molecules – amino acid (asparagine), VFA (lactate)
and polyamine (putrescine) are admitted to interact with the fundamental
component – Kagome-PNT at two distinct spots – hollow and triangle.
This form of interaction is performed based on the work of Ralph H
Scheicher [49, 50], where the spots with small binding energy is
chosen as global minima spot. The interaction of asparagine, lactate and
putrescine on Kagome-PNT are specified as Complex X, Y and Z (1-hollow;
2-triangle) to enable pleasant interpretation for the readers and are
illustrated in Fig. 5 (a) – (c).

and triangle site (complex X2) of Kagome-PNT.
