Patent number: 11814720Abstract: A method for fabricating structures includes on a substrate includes providing the substrate having a substrate surface, and generating nanostructures or microstructures on the substrate surface at least in part by exposing the substrate surface to thermal particles from a thermal particle source while irradiating the substrate surface with an ion beam. The generated nanostructures or microstructures have a smaller surface area than the area of incidence of the ion beam or a beam generated by the thermal particle source. The method also includes obtaining a measurement of a characteristic of the substrate surface and adjusting at least one of the thermal particle source and the ion beam based on the measurement.Type: GrantFiled: October 20, 2020Date of Patent: November 14, 2023Assignee: Purdue Research FoundationInventors: Jean Paul Allain, Osman J.

Publication number: 20200129669Abstract: Provided herein are magnesium-based sponges and foams and methods for surface modification to enhance bioactivity. The magnesium-based sponges and foams may be useful as tissue or bone grafts which promote cellular adhesion and osseointegration and conduction, as well as various other biological functions including, for example, antibacterial properties, hydrophobicity or hydrophilicity and the ability to modulate immune response. The described sponges and foams have precise mechanical properties which are specifically designed for enhanced integration with surrounding tissue. The described magnesium-based materials are bioresorbable, allowing for the gradual, safe absorption of the material when exposed to bodily fluids.Type: ApplicationFiled: October 3, 2019Publication date: April 30, 2020Applicant: The Board of Trustees of the University of IllinoisInventors: Jean Paul ALLAIN, Akshath SHETTY, Juan Fernando RAMIREZ PATINO, Viviana POSADA, Patricia FERNANDEZ MORALES
