This thesis presents the experimental work with the main aim of developing a new approach for the study and characterization of organic nanoparticles by using electrochemical method in aqueous solution. The first chapter introduces the principles and techniques of electrochemistry while the second chapter gives a brief introduction to the synthesis of organic nanoparticles, the modification of electrodes and the monitor of organic nanoparticles via electrochemical and existing characterization techniques. This thesis reports the experimental work on detecting a variety of organic nanoparticles synthesized by reprecipitation method via two main electrochemical methods. For stripping voltammetry, the reduction/oxidation potential of organic nanoparticles in aqueous solution was obtained and the number of electrons transferred was quantified by analytical expressions for reductive/oxidative peaks. For the novel electrochemical method “nano-impacts”, a suitable potentiostatted electrode is immersed in an organic nanoparticles solution so that reduction/ oxidation of a single organic nanoparticle upon its collision on the surface of the electrode. It is shown that this method is capable to characterize the size of monomeric organic nanoparticles and bifunctional organic nanoparticles, the doping of polymeric nanoparticles and the ion-insertion of individual organic nanoparticles. Sticking and stripping technique was also successfully applied to quantify and immobilize the polymeric nanoparticles in aqueous solution.
