New emerging micro-invasive bone grafting techniques have recently risen the interest towards injectable calcium phosphate cement (CPC) as bone filling material that is able to set itself within the body temperature. There are various formulations of injectable CPC that have been developed in recent years. The development of injectable CPC mainly focuses on getting optimum setting times, mechanical properties, injection capabilities and in vivo properties so that the cement is clinically applicable for orthopedic, dental, craniofacial and maxillofacial, vertebroplasty and kyphoplasty, and drug delivery applications. The existing studies on injectable CPCs have investigated the effects of some factors, such as liquid to powder (P/L) ratio, types solid and liquid phase used, concentration of the liquid phase, density and porosity of the cement, particle size of the cement powder and its crystallinity, needle size, and use of setting retardants, setting accelerators and cohesion promoters on the handling, mechanical and biological properties of the cement. The aim of this paper is to review the recent developments of injectable CPC for bone filling materials. Some prominent patents related to the developments of injectable CPC are also reviewed

Wound infections arising from bacterial contamination and colonisation are of substantial burden to healthcare. Currently, bandages are used to merely provide wounds with physical barriers to bacteria, however they quickly become saturated and ineffective. Silver containing wound dressings have gained commercial and scientific attention as a potential solution to the problem of wound infections. In this work, we compare the antibacterial efficacy of recently patented silver nanoparticle loaded plasma polymer film technology and a commercially available GranuFoam Silver® silver-coated wound dressings. The silver nanoparticle loaded foams contained lower amount of elemental silver than the commercially available wound dressings but both silver-loaded foams had comparable antibacterial capacity. Furthermore, the silver nanoparticle loaded foams had greater hydrophilicity which may be beneficial in applications. Collectively, the results demonstrate that the nanoparticle loaded plasma polymer coating can be used on medical devices such as wound dressings with similar efficacy to existing products.

In this short statistical report, we compile and analyze statistics on past and current scientific and technological research on photosensitive glass (PG) as well as glass-ceramics (GC). Their developments have traced remarkable histories since their first commercial discoveries in the 1940s and 1950s, both the work of Don Stookey. These products and processes have transformed modern life and are two of the most widely reported methods for special glass manufacturing. They provide security, are of high quality mass production. The U.S., Japan and China have been leaders in PG glass development, the second place going to China in terms of GC research communities. We have observed very significant progress in recent decades with an exponential growth in the number of scientific publications and patents for PGs and GCs due to new publications, author keywords, affiliations and primary characterization techniques. More than 6,497 patents were filed globally prior to 2015 with the terms “photosensitive and glass” and 9,738 with the terms “glass and ceramics” within the title or abstract according to the European Patent Office. These numbers have continued to grow along with worldwide PG and GC-related sales. Based on the Scopus database, for the same period 1,405 PG documents and 30,819 GC-related (primarily manuscripts) were published with the same terms in the title, abstract or keywords list. From this statistical analysis, both PG and GC will continue to be fascinating materials for further research, development and uses in the near future.
