Surface modification of praseodymium oxide/hematite doped into Polycaprolactone for enhanced wound management demands

Praseodymium oxide (Pr₆O₁₁), hematite (Fe₂O₃), graphene oxide (GO), and polycaprolactone (PCL) based polymeric nanocomposites (NCs) are fabricated, aiming their usage as bio-scaffold for medical purposes. Because of their distinctive light absorption and stability, Fe₂O₃ and Pr₆O₁₁ have been introduced as potential optical elements. The structure and size examination of NCs were executed by XRD, Raman, and FESEM. Pr₆O₁₁/Fe₂O₃/GO@PCL polymeric NC is exhibited Pr₆O₁₁, and Fe₂O₃ average size of 1.4, 0.4 µm, while average pores size 2.1 µm. As well, the Uv–Vis shows an absorption edge shifting along the x-axis that it begins with 3.1 eV for pure PCL, after that it declined to 1.7 eV for Pr₆O₁₁@PCL NC. Also, Pr₆O₁₁ @PCL, and Pr₆O₁₁/ Fe₂O₃@PCL NCs show the lowest similar contact angle with 38°. Regarding cell attachment evaluation test, the Pr₆O₁₁/Fe₂O₃/GO@PCL NC healing valuation is touched ∼ 80%. As a result, the structure enabled 3-dimensional the division of normal cells, so promoting wound healing.
