Abstract

The need for natural, biodegradable, and biocompatible nanomaterials in drug delivery led to a great deal of interest in developing nanocellulose-based materials. This article emphasizes the potential of different types of nanocellulose in improving targeted intracellular drug delivery of biological and non-biological therapeutic molecules. Several new concepts and methods of employing nanocellulose to deliver therapeutic molecules, including less-studied biological agents, have been reviewed. Different types of nanocellulose, methods to extract or synthesize them, and various factors like size, shape, surface charge, hydrophilicity, etc. that affect intracellular drug delivery have also been discussed. Lastly, we discuss the current limitations associated with the extraction/synthesis of nanocellulose and its usage in targeted drug delivery, along with future prospects, including possible solutions to address the current challenges.
