Summary of "Characterization of an antibacterial wound dressing from basil seed (Ocimum basilicum L.) mucilage-ZnO nanocomposite."

The large water holding capacity of Basil Seed (Ocimum basilicum L.) Mucilage (BSM) gives it potential to produce a valuable polymer for water holding applications such as wound dressing. The objective of this research was to prepare a natural-based antibacterial wound dressing from BSM by freeze-drying. Various contents of zinc oxide nanoparticles (ZnO-NP) were incorporated as an antibacterial agent. BSM hydrogel sponge showed considerable porosity and degree of swelling. From FTIR analysis, hydrogen bond and electrostatic interaction between BSM molecules and ZnO-NP were confirmed. SEM images revealed an interconnecting open-cell structure of pores in the BSM hydrogel sponge with a good distribution of ZnO-NP. Moreover, increase in ZnO-NP content improved the mechanical properties (stress at maximum load 8.9 MPa, Young's modulus 151 MPa and strain at maximum load 51%), thermal properties, water retention capacity and antibacterial activity. Cytotoxicity and cell adhesion studies of BSM hydrogel sponge indicated non-cytotoxicity and non-adherent nature of the sponge.

Medical and Biotech [MESH] Definitions

A plant genus of the family Lamiaceae which occurs in tropical and warm temperate regions worldwide. It includes the aromatic herb OCIMUM BASILICUM (Sweet Basil) and the MEDICINAL PLANT Ocimum tenuiflorum (Holy Basil).

The application of a vacuum across the surface of a wound through a foam dressing cut to fit the wound. This removes wound exudates, reduces build-up of inflammatory mediators, and increases the flow of nutrients to the wound thus promoting healing.

A plant species of the genus OCIMUM, family LAMIACEAE that has been used in TRADITIONAL MEDICINE.

A plant species of the genus OCIMUM, family LAMIACEAE. It is a condiment with carminative properties.

Removal of degenerated and necrotic epithelium and underlying connective tissue of a periodontal pocket in an effort to convert a chronic ulcerated wound to an acute surgical wound, thereby insuring wound healing and attachment or epithelial adhesion, and shrinkage of the marginal gingiva. The term is sometimes used in connection with smoothing of a root surface or ROOT PLANING. (Jablonski; Illustrated Dictionary of Dentistry, 1982)
