Synthesizing hydroxyapatite of L-arginine desired morphology by a prior and conscious manipulation of interfacial electrostatic interaction has been a Ultrasonication challenge to be addressed in the arena of biomaterials research. In the present study, L-arginine as an amino acid Amino acids has been chosen as a growth modiﬁer of hydroxyapatite particles, as its isoelectric point (10.75) is comparable to Isoelectric point the conducive alkaline pH for the synthesis of hydroxyapatite and consequently owing to its strong interaction of Density functional theory guanidino group below the isoelectric point with phosphate group of hydroxyapatite than its counterparts. Further, eﬀorts have been made to investigate the
