In this study, selenium nanoparticles (SeNPs) were synthesized using polysaccharides extracted from blueberry pomace (BP) as a stabilizing agent. BP was characterized as an acidic polysaccharide with a molecular weight of 5.4 × 105 Da. The resulting BP-SeNPs were monodisperse spheres with an average size of 94.33 nm, as confirmed by TEM, DLS, FT-IR, XRD, and EDX analyses. Compared to SeNPs, BP-SeNPs demonstrated superior stability under varying conditions of storage time, temperature, pH, and ionic strength. Furthermore, in vitro evaluation using AAPH-induced rabbit erythrocytes revealed that BP-SeNPs offered enhanced protection against hemolysis. This protective effect was attributed to their ability to significantly bolster antioxidant enzyme activities (SOD, CAT, and GSH-Px) and preserve membrane integrity by maintaining ATPase function and sialic acid content. These results establish BP as an effective stabilizer for SeNPs and suggest the promising potential of BP-SeNPs as antioxidant agents in functional food or nutraceutical applications.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork.
