Recent advancement in nanoengineered technologies that use surface acoustic waves of variable frequency and amplitude have sparked significant interest among researchers in the field of bio nano electromechanical systems (Bio-NEMS/MEMS). The increased fascination with vibrating surfaces due to their acoustic streaming possibilities, is the driving force behind this research. These surfaces have outstanding physiochemical characteristics that make them extremely adaptable for a variety of applications, including fluidics, tissue engineering, targeted drug delivery, enhanced oil recovery, etc. In the present work, the study of the vibrating nano platinum surface has been carried out to analyze the effect of surface wettability, resistance force, and mean square displacements to obtain the desired performance using molecular dynamics simulations (MDS). A modified Lennard-Jones (LJ) potential was used to control the mobility of water molecules using a solid–liquid. The optimum performance of the nano surface for the desired application is obtained at higher amplitude (5 Å) and frequency (300 GHz) respectively. The average resistance force (FR) for high configuration surface vibrations increased to 80.14% i.e. from 4.4394 × 1014 kJ/mol/m, compared to 8.818 × 1013 kJ/mol/m at amplitude (2 Å) and frequency (50 GHz) configuration. This shows that the present work has substantial implications for applications towards nano technologies. |
