Biomaterial Surface

A biomaterial surface is the physical and chemical interface between a medical implant and the host's biological environment. It is not a specific molecular target but a complex site where immediate protein adsorption and subsequent cellular interactions occur, determining the success or failure of the implant (Ratner et al., 2012). These surfaces are critical in medical device engineering, as they can be modified with drugs like paclitaxel or sirolimus to prevent restenosis in cardiovascular applications or coated with antibiotics to prevent infection (Anderson et al., 2008). The biological response is influenced by surface properties such as topography, hydrophobicity, and chemical composition, which can trigger the foreign body response or promote tissue integration like osseointegration in orthopedic implants (Vogler, 2012). Understanding these interactions is essential for developing biocompatible materials that minimize adverse effects like thrombosis and chronic inflammation.

Biomaterial surfaces serve as substrates for drug delivery or surface modification to modulate biological responses, such as inhibiting neointimal hyperplasia or preventing bacterial adhesion.
