Surface Plasmon Resonance in 3D-Printed Porous Biosorbent Scaffolds for Heavy-Metal Capture and Resource Recovery

PROBLEM: 3D printing can place plasmonic regions in defined pore geometries for capture, but the printed scaffold must then be functionalized with biosorbent without clogging the designed pores or burying the plasmonic interface. If functionalization fills the smallest channels, flow bypasses both the capture surface and the plasmonic readout; if it is too sparse, capacity falls. A successful printed capture run cannot be repeated without a versioned record of the pore design and functionalization.

SOLUTION: Storage Copy Data Management would preserve versioned copies of each plasmon-enhanced 3D-printed capture scaffold, linking the pore geometry and plasmonic placement to its DFT prediction, its isotherm validation, and its regeneration record. The capability would support reproducibility checks and retention so a recovery result can be traced to the exact printed scaffold that produced it.

EVIDENCE BASIS: DOCUMENTED — surface plasmon resonance is collective electron oscillation at metal–dielectric interfaces, with field enhancement for sensing; 3D-printed porous scaffolds provide architected pore networks, print-then-functionalize; DFT predicts which surface groups bind which metal ions; biosorption follows R−COOH + M2+ ⇌ R−COOM+ + H+ with Langmuir and Freundlich isotherms.
