A Review of Organic Dye Based Nanoparticles: Preparation, Properties, and Engineering/Technical Applications

Abstract

Abstract: Organic dye-based nanoparticles (ODNPs) are fabricated with desired morphologies using laser ablation, reprecipitation, ion association, and self-assembly methods. Primitively, this review in.troduces the theory of the molecular origins of dye aggregation, manifestations of the formations of monomer to J-dimer, H-dimer, and oblique dimer (mixed J and H dimer) in ODNPs. Although, organic dye nanoparticles have better basic properties than their monomer counterparts. These nanoparticles are suitable candidates for many engineering and technical applications. Furthermore, we have dis.cussed OLEDs, optoelectronics, sensing, environmental, light-harvesting antennas, cryptography, and biomedical imaging applications. The conclusion made from the critical review analysis opens up a new horizon for the future development of ODNPs applications.
