Journal ArticleDOI
Plasma-surface modification of biomaterials
TL;DR: This article reviews the various common plasma techniques and experimental methods as applied to biomedical materials research, such as plasma sputtering and etching, plasma implantation, plasma deposition, plasma polymerization, laser plasma deposited, plasma spraying, and so on.
Journal ArticleDOI
Antithrombogenic investigation of surface energy and optical bandgap and hemocompatibility mechanism of Ti(Ta(+5))O2 thin films.
TL;DR: The calculated results reveal that the smaller surface force gamma(s) of the film and the smaller blood film interfacial tension gamma(c,blood) are partially responsible for the enhancement of the blood compatibility.
Journal ArticleDOI
Blood compatibility and sp3/sp2 contents of diamond-like carbon (DLC) synthesized by plasma immersion ion implantation-deposition
Junying Chen,Junying Chen,Langping Wang,K. Y. Fu,Nan Huang,Yang Leng,Yongxiang Leng,Ping Yang,Ping Yang,Jin Wang,Guojiang Wan,Hong Sun,Xiubo Tian,Paul K. Chu +13 more
TL;DR: In this paper, the effects of reactive gas pressure and flow ratio on the characteristics of the diamond-like carbon (DLC) films are systematically examined to correlate to the blood compatibility.
Journal ArticleDOI

Yongxiang Leng,Yongxiang Leng,Hong Sun,Ping Yang,Ping Yang,Junying Chen,Junying Chen,J. Wang,Guojiang Wan,Nan Huang,Nan Huang,Xiubo Tian,Langping Wang,Paul K. Chu +13 more
TL;DR: In this article, the biomedical properties of tantalum nitride thin films synthesized by reactive magnetron sputtering employing orthogonal design technology are investigated, and the results reveal that the blood compatibility of the tantalum-nide films is better than that of TiN, Ta and low-temperature isotropic pyrolytic carbon (LTIC).
Journal ArticleDOI
Third-generation plasma immersion ion implanter for biomedical materials and research
TL;DR: A third generation plasma immersion ion implanter dedicated to biomedical materials and research has been designed and constructed as mentioned in this paper, which consists of four sets of high-efficiency metal arc plasma sources with magnetic filters, a custom designed high voltage modulator for operation up to 60 kV, a separate high-frequency, lowvoltage power supply for hybrid treatment processes, a special rotating sample stage for samples with an irregular shape, and other advanced features.
