Pore-scale Reaction Imaging

Pore-scale reaction imaging is a specialized approach for observing and measuring chemical reactions within the interconnected pores of a porous material, where microscale structure controls transport and reactivity. It combines spatially resolved imaging with information about fluid movement, reactant distribution, and product formation to link local pore geometry with reaction behavior under controlled conditions. In engineering, this approach helps clarify coupled flow, mass transfer, and reaction processes in catalysts, filtration media, subsurface formations, and energy-storage materials. By revealing where reactions occur and how they alter pore structure, pore-scale reaction imaging improves models of porous systems and supports more efficient material and process design.

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.
