• Biomineralization-inspired design explores how organic matrices guide mineral morphogenesis to yield biomimetic fluorapatite‑gelatin composites and CaCO3 polymorphs, connecting structure to function across dental and bone contexts [18], [16], [6], [10], [19], [14].

• Patterning and microfabrication of biomolecular interfaces using elastomeric membranes, microcontact printing, and microfluidic networks enable spatial control of cells and proteins on polymer substrates, driving defined biointerfaces [1], [17], [15], [20], [13].

• Sol-gel encapsulation approaches unify ceramics and organic matrices to protect labile biomolecules and create functional bioactive composites, offering versatile generic methods for biomaterial design [3], [4].

• Surface functionalization strategies tune cell–material interactions by introducing bioactive groups and patterning ligands (e.g., biotin/streptavidin) on polymer substrates, enabling defined and responsive interfaces [2], [20], [1], [15].
