Abstract:

We prepared cerium oxide nanoparticles having size range of 160 nm by using simple and effective sol–gel process and evaluated its wound healing potential. Quite interestingly we found that 2% nanoceria enhanced wound healing activity to a considerable extent which could be supported by increased amount of Hydroxylproline content (4.7 g/ml), wound tensile strength of 44.88 N/cm2 and wound closure time, which are quite high when compared to other treated groups. Histopathology also showed no inflammation and increased amount of collagen production in group treated with 2% nanoceria. The prepared nanoparticles were characterized by SEM and XRD. The probable mechanism may be due to the dual oxidation state of cerium oxide which will help in scavenging ROS and reduce oxidative stress locally which is required for wound healing.

More about this publication?
  • Bionanoscience attempts to harness various functions of biological macromolecules and integrate them with engineering for technological applications. It is based on a bottom-up approach and encompasses structural biology, biomacromolecular engineering, material science, and engineering, extending the horizon of material science. The journal aims at publication of (i) Letters (ii) Reviews (3) Concepts (4) Rapid communications (5) Research papers (6) Book reviews (7) Conference announcements in the interface between chemistry, physics, biology, material science, and technology. The use of biological macromolecules as sensors, biomaterials, information storage devices, biomolecular arrays, molecular machines is significantly increasing. The traditional disciplines of chemistry, physics, and biology are overlapping and coalescing with nanoscale science and technology. Currently research in this area is scattered in different journals and this journal seeks to bring them under a single umbrella to ensure highest quality peer-reviewed research for rapid dissemination in areas that are in the forefront of science and technology which is witnessing phenomenal and accelerated growth.
