Preparation of submicron particles for theranostic applications : imaging and therapy

Abstract : The objective of this study was to prepare and characterize multifunctional submicron particles that can be used for diagnosis and therapy of several fatal diseases including cancer (i.e theranostic). For this purpose, a systematic study was performed in order to optimize the process parameters for preparation of polymeric particle that can be used as a platform for effective delivery of drugs and imaging labels. The imaging agent (FluoSpheres®) was encapsulated via double emulsion solvent evaporation technique to be used fluorescent contrast agent and their in vitro evaluation was performed. Then, gold nanoparticles were prepared by using NaBH4 reduction method, characterized and encapsulated by polycaprolactone polymer for in vitro applications. Finally, the gold nanoparticle were loaded into polycaprolactone particle along with a hydrophilic drug (Nefopam) and a hydrophobic drug (benzyl benzoate) simultaneously. The prepared particles were then characterized physicochemically and in vitro skin penetration study was performed
