Provided herein are methods for the controlled, independent modification of the surface of magnesium-based materials and compositions generated thereby. The methods allow for the alteration of multiple surface characteristics including generation of precise nanostructures, morphology, crystallography, chemical hybridizations and chemical composition for controlled bioresorption and/or increased biocompatibility, for example, osseointegration, hydroxyapatite formation, osseoconduction, cell adhesion, cell proliferation, enhanced local mechanical properties (elasticity, modulus, surface texture, porosity), hydrophobicity, hydrophilicity, steric hindrance, modulating-immuno response, anti-inflammatory properties and/or anti-bacterial properties.

Provided herein are systems and methods for the controlled surface modification of a material substrate, including, for example, generation of nanostructures, crystallographic or morphologic alterations and the removal of defects, changes in chemical composition and bond structure and the creation of thermodynamic metastable states. The provided systems and methods utilize one or more directed energetic particle beams with independently controlled parameters (e.g. incident angle, fluence, flux, energy, species, etc.) to precisely and efficiently generate enhanced surface properties beyond those of conventional plasma kinetic roughening.
