Biological voyage of solid lipid nanoparticles: a proficient carrier in nanomedicine.

This review projects the prospects and issues faced by solid lipid nanoparticles (SLNs) in current scenarios, specially related to its clinical implementation and effectiveness. We re-examine the basic concept of biobehavior and movement of SLNs as a nanomedicine carrier. The extensive survey of the uptake and absorption mechanism from different routes, distribution pattern, targeting efficiency, effect of surface functionalization on biodistribution, elimination pathways and toxic effects have been documented. In general, the objective of this review is to boost our knowledge about the interaction of SLNs with the bioenvironment, their movement in, and effect on, a living system and future prospects.
