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.
