The biodegradable and biocompatible nature of cellulose along with its natural origin and availability resulted in its application as tissue scaffold, bio composite for wound healing and dressing, drug delivery system and blood purification [66]. Purification could be carried out both by membranes and microbead shaped composites [67, 68]. It also spawned the development of commercial products for skin grafting, dental implants, temporary skin, cornea scaffolds, artificial blood vessels, and wound dressing material [69]. Cellulose has also been used for drug delivery [70–74]. Owing to its rigid matrix, cellulose is adept at supporting cellular structures on its framework. This property along with its biocompatibility leads cellulose a promising prospect for tissue engineering. For instance, Ninan et al. have reported cellulose bio composite as an effective support for fibroblast cell line [75] while Muller et al. used cellulosic support for cartilage cell growth [76]. Besides, cellulose nanocrystals are attracting attention for their applications in tissue engineering [77] while nanoscale cellulose materials are being studied as well [78].
