1. A process providing a method for coating a titanium (Ti) biomedical implant with nanofiber including the steps:
polishing a surface of said implant;
amending said surface effecting at least one of groves and ridges;
exposing said surface to plasma O2;
applying a collagen solution to said surface;
producing electrospun nanofiber (ENF) made with at least Polycaprolactone (PCL);
depositing said ENF on said surface within said at least one of grooves and ridges;
wherein said ENF and collagen form a nanofiber matrix (NFM), and said NMF is adapted to bond within said at least one of grooves and ridges.
