Protein and lipid nanomaterial-based functional constructs represent a cutting-edge platform for targeted drug delivery, diagnostics, and therapeutic modulation. These hybrid nanomaterials provide improved stability, controlled release, and precise targeting capabilities by fusing the specificity and functional variety of proteins with the biocompatibility and customisable structure of lipids. Protein components, such as antibodies, enzymes, or ligands, allow receptor-mediated targeting and immunological regulation, while lipid nanoparticles make it easier to transport hydrophobic medications, nucleic acids, and peptides. These constructions are being used more and more in the creation of vaccines, infectious diseases, cancer treatment, and neurological disorders. Stimulus-sensitive release and enhanced pharmacokinetics are further made possible by the combination of responsive design and sophisticated surface engineering. Protein and lipid hybrid nanoplatforms are anticipated to help with the existing issues of therapeutic resistance, off-target toxicity, and bioavailability as research progresses, opening the door for next-generation precision medicine. Recent developments and possible uses of these multipurpose nanostructures in several biomedical fields are highlighted in this abstract.
