ABSTRACT
All humans have unique gene sequences, and genetic tests can suggest a predisposition to certain illnesses, such as breast cancer, cystic fibrosis or liver diseases, thus providing better cure or even prevention. Scanning electron microscopy proved very useful in studying the supramolecular lattice formed when functionalised carbon nanotubes (CNT) were exposed to different ratios of plasmid. To confirm the obtained results, an elution model was associated with the experiments in order to elucidate the most significant factors contributing to the separation of carbon nanotubes -deoxyribonucleic acid CNT- deoxyribonucleic acid (DNA) hybrids. An interesting work has been published on small interfering ribonucleic acid for targeted cancer therapy. DNA oligonucleotides can represent a valuable tool able to identify the interaction of small-molecule ligands targeting specific proteins or protein receptors. W. Wu et al. showed that the oligonucleotides not only act as coding sequences for the linked organic molecules but offer immediate signal amplification via polymerase chain reactions.
