Nanobulges: A Duplex Nanosystem for Multidimensional Applications

Background: Nanoparticulate systems like nanospheres, nanocrystals, and nanofluids show immense advancement in the fields of nanoelectronic and agriculture. Nanobulges are duplexed nanoparticles comprising the interaction of two nanoparticles for the formation of a curved bulge on the surface of the nanoparticle. Objective: This review focuses on properties, mechanism of action, methods of preparation and applications of nanobulges in optoelectronic devices and controlled release of fertilizers. Methods: Mostly pulsed laser deposition and multilayered palladium-catalysts fabrication with nanobulges structure are used to prepare nanobulges. Results: Nanobulges are advantageous over the conventional nanoparticles due to their high electrical density, improved catalytic drug loading and good electronic conductivity. Conclusion: In the near future, nanobulges will emerge as a promising material for commercial preparation of bioanalytical sensors and microfluidic systems.
