Latest Patents
One of his latest patents is titled "Peptoids useful for the mineralization of apatite." This invention provides a bio-mimetic polymer capable of catalyzing or mineralizing calcium ions and phosphate ions into apatite. Another significant patent is for "Glass/ceramic coatings for implants." This patent describes the preparation of glass coatings on metals such as Ti, Ti6A14V, and CrCo for use as implants. The composition of these glasses is tailored to match the thermal expansion of the substrate metal. By controlling the firing atmosphere, time, and temperature, it is possible to manage the reactivity between the glass and the alloy, resulting in coatings with excellent adhesion to the substrate. The optimum firing temperatures for these coatings range between 800 and 840°C, with times up to 1 minute in air or 15 minutes in nitrogen. This technique also allows for the creation of multilayered coatings with concentration gradients of hydroxyapatite (HA) particles and SiO.
