Special Issue Information

Dear Colleagues,

Research into the use of calcium phosphates in the development and clinical application of biomedical materials has been a significantly diverse activity by a wide range of scientists, engineers and medical practitioners, among others. The field of research in this area can hence be truly defined as interdisciplinary and much interesting work leading to imaginative and innovative solutions for the improvement of health outcomes continues.

It is the intention of this Special Issue to summarize a wide selection of the current advances in this area. We thus invite contributions to this issue in the form of original articles, review articles, research notes and short communications from various areas of this scientific discipline. Areas of interest that could be covered are contributions based on uses of natural by products to form potential biomaterials, novel composites of calcium phosphates with other materials, chemical manipulations of calcium phosphates that lead to novel biomaterials, studies advancing further the cell biology surrounding the incorporation of calcium phosphate biomaterials, engineering/biomechanical aspects of using calcium phosphate biomaterials and human or animal clinical studies involving calcium phosphates. Studies on novel approaches to characterization to study these materials would also be of interest.  Other types of contribution welcomed would be from those involved with regulating the use of calcium phosphate biomaterials. Hence, we invite, scientists, engineers, doctors, and medical device regulators to submit articles of interest.

It is hoped that this Special Issue will be enriched with these very diverse topics that provide an overall picture of advancements in this area.

We look forward to your contributions. Each article will be subject to rigorous peer review.

Glow discharge plasma (GDP) treatments of biomaterials, such as hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) composites, produce surfaces with fewer contaminants and may facilitate cell attachment and enhance bone regeneration. Thus, in this study we used argon glow discharge plasma (Ar-GDP) treatments to modify HA/β-TCP particle surfaces and investigated the physical and chemical properties of the resulting particles (HA/β-TCP + Ar-GDP). The HA/β-TCP particles were treated with GDP for 15 min in argon gas at room temperature under the following conditions: power: 80 W; frequency: 13.56 MHz; pressure: 100 mTorr. Scanning electron microscope (SEM) observations showed similar rough surfaces of HA/β-TCP + Ar-GDP HA/β-TCP particles, and energy dispersive spectrometry analyses showed that HA/β-TCP surfaces had more contaminants than HA/β-TCP + Ar-GDP surfaces. Ca/P mole ratios in HA/β-TCP and HA/β-TCP + Ar-GDP were 1.34 and 1.58, respectively. Both biomaterials presented maximal intensities of X-ray diffraction patterns at 27° with 600 a.u. At 25° and 40°, HA/β-TCP + Ar-GDP and HA/β-TCP particles had peaks of 200 a.u., which are similar to XRD intensities of human bone. In subsequent comparisons, MG-63 cell viability and differentiation into osteoblast-like cells were assessed on HA/β-TCP and HA/β-TCP + Ar-GDP surfaces, and Ar-GDP treatments led to improved cell growth and alkaline phosphatase activities. The present data indicate that GDP surface treatment modified HA/β-TCP surfaces by eliminating contaminants, and the resulting graft material enhanced bone regeneration. Full article
