Aptamer-based technology for radionuclide targeted imaging and therapy: a promising weapon against cancer

Abstract excerpt

INTRODUCTION: aptamers are short artificial, single-strand oligonucleotide sequences (DNA, RNA or modified RNA), capable of binding to biological molecules with high affinity and specificity. Due to their relatively low cost of production and scarce immunogenicity, many efforts have been made to produce aptamers directed against specific molecular targets, such as receptors or transporters overexpressed by...
