Lignin-Based Nanomaterials as Drug Delivery Vehicles: A Review

Over the past decade, lignin-based nanomaterials have astonishingly gained tremendous popularity among researchers worldwide for utilization in various high-value added fields. However, the copiousness of published articles suggests that lignin-based nanomaterials are currently being given the most priority as drug delivery vehicles or drug carriers. A large number of reports have been published during the past decade reporting successful application of lignin nanoparticles as drug carrier, not only for drugs administered in human but also for drugs used in plants such as pesticides, fungicides, etc. In this review, all of these reports have been discussed in an elaborate fashion so as to present all the available information pertaining to the application of lignin-based nanomaterials in drug delivery in a comprehensive manner.
