Natural materials for nano bio systems

Many papers have been published on the properties of deoxyribonucleic acid (DNA) and DNA-hexadecyltrimethylammonium chloride (CTMA) and their applications in electronics and photonics. This paper is a review of some of the properties and their related applications for other types of naturally occurring materials, nucleic acid bases or nucleobases which make up the DNA molecules. Nucleobases under investigation included guanine, cytosine, adenine and thymine. Potential applications include electron blocking layers for organic light emitting diodes, gate dielectrics for organic thin film transistors and protective layers for polymer-based capacitors.
