Abstract: Cellulose Nanocrystals (CNCs) have been touted to be among the materials of the 21st
century. It is an emerging biocompatible and biodegradable nanomaterial with unique physicochemical
properties adaptable to various surface modifications. The characteristics and properties
of CNCs are now understood to depend upon the source of the cellulose and the conditions of its
isolation. Over the past decade, CNCs with various morphologies, including rod, ribbon, needle
shapes, spherical, square, block and rectangular shapes with unique surface properties, have been
synthesized. Studies have shown that surface and morphological properties of CNCs have substantial
control over the rheology, cytotoxicity and cellular uptake, which ultimately influence its
purposive biomedical applications. The objective of the current survey is to analyze the advances
made in the shape-controlled synthesis and fabrication of CNCs morphology and review the influence
such morphological variations have on its functionality in biomedical fields.
