چکیده
This paper compares two types of polylactic acid (PLA) coating on AZ31 alloy obtained by dip and electrospinning. Both were loaded with gentamicin sulphate (GS) the drug-loading efficiency release assessed. A higher encapsulation GS was seen for (73% 49.53%, respectively) compared to nanofiber (65% 12.37%, respectively). Furthermore, antibacterial effect samples without assessed using Gram-negative (Escherichia coli) Gram-positive (Staphylococcus aureus) bacteria, showing that drug encapsulated are more resistant bacteria than other samples. The electrochemical data reveal a stability in SBF surface dipping PLA shows porosity 46% sample through 32% nanofibers, which is accordance BET analysis results. Moreover, adhesion strength AZ31-PLA-dip (4.99 MPa) AZ31-PLA-nanofibers (1.66 MPa). All structurally, morphologically, topographically characterized.
