CVD processing is a cornerstone of manufacturing for semiconductor products, optics, sensors, and displays. It is also established for surface modification of products like cutting tools and windows. Industrial CVD processes are not just hatched, they are conceived, born, weaned, nurtured through their testy adolescence, and finally brought to maturity and industrial production through research – a lot of research. Consider light emitting diodes (LEDs). The red GaAs LED was reported in 1955 by researchers at RCA Laboratories butmass production would take a further thirteen years. CVD manufacturing processes for biomaterials are not currently available. If we want to explore the future development possibilities, we need to examine the CVD biomaterials research of today. This special issue surveys the latest developments in CVD biomaterials with the aim of gaining a broad perspective. It is impossible to tell, at this point, which of the various types of CVD biomaterials or processes presented in this issue will grow up to find industrial application. However, this special issue does highlight several possibilities. A scan through the literature gives an appreciation of the range of materials and applications. Research into biomaterials is necessarily crossdisciplinary. This is the same situation that has existed for thirty years in semiconductor device manufacture,
