Abstract: Compared to the conventional approach, nanoparticles (NPs) facilitate a non-hazardous,
non-toxic, non-interactive, and biocompatible system, rendering them incredibly promising
for improving drug delivery to target cells. When that comes to accomplishing specific therapeutic
agents like drugs, peptides, nucleotides, etc., lipidic nanoparticulate systems have emerged as
even more robust. They have asserted impressive ability in bypassing physiological and cellular
barriers, evading lysosomal capture and the proton sponge effect, optimizing bioavailability, and
compliance, lowering doses, and boosting therapeutic efficacy. However, the lack of selectivity at
the cellular level hinders its ability to accomplish its potential to the fullest. The inclusion of surface
functionalization to the lipidic NPs might certainly assist them in adapting to the basic biological
demands of a specific pathological condition. Several ligands, including peptides, enzymes,
polymers, saccharides, antibodies, etc., can be functionalized onto the surface of lipidic NPs to
achieve cellular selectivity and avoid bioactivity challenges. This review provides a comprehensive
outline for functionalizing lipid-based NPs systems in prominence over target selectivity. Emphasis
has been put upon the strategies for reinforcing the therapeutic performance of lipidic nano
carriers' using a variety of ligands alongside instances of relevant commercial formulations.
