MINI-REVIEW: FLUORESCENT ORGANIC NANOPARTICLES

Abstract

Fluorescent Organic Nanoparticles have increasing attention in research due to the wide variety of available organic molecules, the flexibility in material synthesis, their excellent water solubility, and favorable optical properties. FONs are emerging as a new class of fluorescent probe for sensing and estimation of carcinogens from the environment, bio-molecules in pharmaceutical samples and DNA due to their peculiar size dependent optical and electronic properties and superior photostability and excellent resistance to chemical degradation or photodegradation. The different kinds of methods used for the preparation of FONs are the supercritical fluid crystallization, microwave-irradiation reprecipitation, emulsion, laser ablation and reprecipitation method. The methods are employed under different conditions of temperature, precipitation time, template and stabilizer to acquire organic nanoparticles with different structures, various shapes, and of diverse sizes. The unique and more applicable properties of the prepared nanoparticles have as compared with the property of the monomer and bulk materials.
