Abstract

The advanced study of nanocarbon molecules as bioactive molecules allows fundamental investigation and developing biotechnologies to obtain biocompatible materials with immobilized surface. To use nanocarbone molecules (fullerene and short carbon nanotubes CNT) in biocells it is necessary to immobilize the surface of molecules for preparing aqueous and biosolution with high molecule content, which forms nanofluids. Fullerene or CNT fluids - several molecules С60 and CNT surfaces - novel water soluble fullerene and CNT derivatives with oxygen groups and mono and polynucleotides[2]. Using these results we developed biotechnology of nanocarbon fluids design in water and biosolutions as model cells. Comparative analysis photoluminescent spectra (PL) immobilized C60 and short multi-walled CNT fluids was carried out after identification tailoring molecules by methods of absorption spectroscopy at UV-vis range and vibration spectroscopy at IR range. The results demonstrate: PL spectra of nanocarbon molecules separately functionalised by mono- (adenosine monophosphate) and poly- (botanical ss- and ds-DNA) nucleotides have intensive band in 550-850nm range excited by light with wavelengths at 325-440nm range. The PL band narrows, intensity increases for nanocarbon fluids changed by the contents of tailoring biomolecules and oxygen, hydroxyl groups.
