In this video, we will demonstrate modification techniques for porous metallic implants to improve their functionality and to control cell migration. Techniques include development of pore gradients to control cell movement in 3D and production of basement membrane mimics to control cell movement in 2-D. Also, a HPLC-based method for monitoring implant integration in-vivo via analysis of blood proteins is described.

Live imaging of cells exposed to the lipophilic dye FM1-43 allows precise determination of the kinetics by which pore-forming toxins are removed from the plasma membrane. This is a sensitive assay that can be used to assess requirements for Ca2+, sphingomyelinase and other factors on plasma membrane repair.
FAQs
Pore geometry determines how fluid and dissolved species access reactive locations, so neighboring pores can experience different reaction conditions. Imaging links these local structural differences with where reactants are distributed and products form. This connection helps engineers distinguish behavior associated with transport, reaction location, and changes within the pore network itself.
Flow controls movement through interconnected pores, while mass transfer governs how reactants reach locations where reactions occur. Reaction then changes the distribution of products and may alter the pore structure. Considering these processes together allows local measurements to explain behavior that would be difficult to interpret from flow, composition, or reaction information alone.
Product formation shows where chemical conversion has occurred and provides a spatial counterpart to reactant distribution. When these observations are related to pore geometry, researchers can examine how reactions are positioned within the material and how the resulting changes affect the pore network. This supports more detailed interpretation of evolving porous systems.
The approach examines porous materials under controlled conditions while recording spatial information about fluid movement, reactant distribution, and product formation. These measurements are interpreted alongside the material’s interconnected pore structure. Organizing the investigation around both local geometry and chemical behavior helps reveal how the system responds during coupled flow, mass-transfer, and reaction processes.
Applications include catalysts, filtration media, subsurface formations, and energy-storage materials. In each case, the method can connect local pore structure with chemical behavior and transport. That information helps engineers investigate why reactions occur in particular regions and assess how pore-scale processes influence the performance of larger porous systems.
Spatial observations provide evidence for how local pore geometry, fluid movement, reactants, and products are related. Engineers can use these relationships to improve models of porous systems rather than relying only on averaged behavior. The resulting understanding supports more efficient design of materials and processes in systems where flow and reaction are coupled.
