Anotācija | Hydroxyapatite (HAP) is in use to fabricate implants in dentistry and orthopaedy. To functionalise a surface of the HAP that has a direct contact to the human cells a surface electrical charge deposition is employed. The current technologies can not provide uniformity of the charge for contrarily situated surfaces. To overcome such the disadvantage a HAP hydrogenation technology has been reached. As the result the surface charge has been engineered. The charge was estimated owing to measurements of the photoelectron emission work function. The later was increased to ∼ 0.2 eV. The negatively charged HAP surface in contrast with the uncharged one attached 10 times more osteoblatic cells and increased their proliferation capacity in 1.6 time |
