Scientific Tracks Abstracts: Polym Sci


Highly fluorescent carbon dots (CDs) and quantum dots (QDs) of average particle size of several nanometers were prepared and characterized. Biocompatible polymers such as polyethylenimine (PEI) and carboxylic-ended polycaprolactone (PCLCOOH) were used for preparation of biocompatible (polymer-dots) nanoconjugates via either chemical or electrostatic interactions. Further, this modality allowed for functionalization of the bioconjugates with cancer targeting agents such as folate and/or antibodies. The prepared conjugates were characterized using electron microscopy (SEM and TEM), fluorescence microscopy (FM), confocal laser scanning microscopy (CLSM), flowcytometry and atomic absorption spectroscopy (AAS). The present study opens new avenue for the application of fluorescent polymer conjugates in several cancer theranostic applications.
