From biology to engineered carrier

The oxygen-binding chemistry remains valuable, but the architecture around it changes.

Central transition

Same oxygen-binding core, different architecture, different physiological constraints.

Natural RBC environment

Compartmentalized control

Membrane separation, redox systems, intracellular metabolism, 2,3-BPG, rheology and spatial control shape how hemoglobin operates inside the vascular system.

Cell-free environment

New coupled variables

Molecular size, polymer stability, P50, oxidation, plasma distribution, viscosity, NO interaction, vascular response and microcirculatory behavior become product-specific design and evidence questions.

BHOC therefore cannot be evaluated only by hemoglobin concentration or theoretical oxygen capacity. The relevant question is whether a defined formulation can load, transport and unload oxygen while maintaining physiologically compatible vascular and microcirculatory behavior in the intended context.
