ABSTRACT
The nanomotors were designed in order to capture polymeric nanoparticles by electrostatic interactions or by the formation of biotin–streptavidin bridges, as a proof of concept of the ability to transport cargo to different locations. The development of tiny nanomotors able to precisely perform complex surgical operations inside a patient, to administrate drugs directly in the diseased tissue, or to analyze the number of pathogenic agents with astonishing accuracy is no longer a science fiction tale. Deoxyribonucleic acid (DNA) is one of the most important molecules in all living organisms on Earth. DNA is copied to ribonucleic acid in order to translate its coded information for protein synthesis. Proteins are probably the most important biomolecules for life. The analysis of pollutants in water, especially heavy metals, constitutes an important research area due to the increased contamination problems in industrialized society.
