Cellulose

Nano crystalline cellulose (NCC) has gained attention in the pharmaceutical industry owing to its biodegradable nature and high mechanical properties. In the present work we reported preparation of NCC from cellulose isolated from a bio-waste, its modification and exploration as drug delivery…
