Coating applications, pharmaceutical drug interactions

A biomaterial is essentially a material that is used and adapted for a medical application [1], Biomaterials can have a benign function, such as being used for a heart valve, or may be bioactive and used for a more interactive purpose such as hydroxyapatite (HA)-coated hip implants [2-5]. Biomaterials are also used every day in dental applications, surgery, and drug delivery (a construct with impregnated pharmaceutical products can be placed into the body, which permits the prolonged release of a drug over an extended period of time) [6-10], The type of material used is also dependent on the anticipated mode of applications, the need for surface functionalization, and the need of the cell types of interest in terms of porosity.
