Later in 2008, Sitharaman et al. evaluated CNT composites in vivo for use as a synthetic bone substrate [42]. This involved the preparation of a porous biodegradable polymer composite with the inclusion of short (20—80 nm) single-walled carbon nanotubes (SWNTs). When the in vivo response of CNTs containing substrates was compared to a control without CNTs, the CNT composite showed 300% increase in bone area as observed in micro-CT analysis and bone area under histological analysis.

There are many definitions of biodegradability expounded by different authors. One publication [3] defines biodegradable polymer composites as "materials obtained from nature or by synthetic route, whose chemical bonds are cleaved at least in one step by enz5mies from the biosphere." T) ical degradation times for various materials, including biopol5miers and biocomposites, have now been estimated and are shown in Table 10.1.
