Background:

• Understanding polymer chain behavior near surfaces is crucial for various applications.
• Previous studies often simplified polymer models or surface interactions.

Purpose of the Study:

• To investigate the conformational behavior of a coarse-grained finite polymer chain near an attractive spherical surface.
• To construct phase diagrams for both nongrafted and end-grafted polymers.
• To explore the implications for protein-ligand interactions and nanosmart material design.

Main Methods:

• Multicanonical Monte Carlo computer simulations were employed.
• Canonical equilibrium data were analyzed over a wide range of sphere radii and temperatures.
• Energetic and structural observables, including gyration tensor-based shape parameters, were calculated.

Main Results:

• Entire phase diagrams were constructed for nongrafted and end-grafted polymers.
• Conformational phases were identified through detailed analysis of calculated observables.
• The model qualitatively represents real systems studied experimentally.

Conclusions:

• The study provides insights into polymer-surface interactions using a simplified model.
• The findings have potential applications in fields ranging from biophysics to materials engineering.
• This research contributes to the design of novel nanosmart materials and understanding complex biological interactions.
