The use of carbon nanotubes (CNTs) in drug delivery is a new, rapidly developing field. Different systems such as polymers, dendrimers, and liposomes have been used for drug delivery, but carbon nanotubes provide more effective structures due to their high drug loading capacities and good cell penetration qualities.

Numerous biological experiments have demonstrated that DNA is the primary intracellular target of anticancer drugs due to the intercalation between small molecules and DNA, which can cause DNA damage in cancer cells, blocking their division and resulting in cell death. So to develop new and efficient DNA intercalators to be used as anticancer drugs is an urgent and important task.

Metal sulfide reduction in the presence of a suitable sulfur-scavenging metal oxide is an attractive process for the direct recovery of metals.

Paramagnetic species, i.e. those containing unpaired electrons, are involved as reactive intermediates in many of the mechanisms devised for catalytic processes. Since these tend to have an intrinsically fleeting existence, to detect and characterise them is difficult. They may take the form, for example of free radicals, paramagnetic redox sites on catalytic surfaces, or be a part of the essential functional centre of an enzyme.

The removal of aromatic pollutants from water is of great importance environmentally and industrially. 2-chlorophenol and phenol-like compounds are categorised as persistent pollutants and many techniques have been presented for the removal of phenolic pollutants from water. Among the most important of such techniques is the application of nanoparticles of magnetic metals such as Fe2O3.

The release of chemical pollutants, such as nitrogen oxides (NO and NO2), into the atmosphere is a major source of acid rain and photochemical smog. Finding methods to control and eliminate these pollutants (NOx) from the troposphere is obviously of great interest and as such, the development of NOx gas sensors for environmental monitoring is desirable.

Historically, based on carbamic acid, a large family of carbamate pesticides have been developed, and are also widely employed as insecticides. In 1988, Goto et al. reported the first synthesis of carbofuran, and also described the biological activity of various amino sulfenyl derivatives of methylcarbamate. Later, the synthesis of several procarbofurans was reported by Gaset et al. These derivatives present a substitution in the nitrogen proton by different organic groups.

Organic sulfur compounds are commonly found in wastewater and sediments and are environmentally significant due to their hideous odour. Sulfur containing organic compounds such as thioacetamide CH3CSNH2 (TAM) have many industrial and non-industrial applications.

The interactions of biochemical compounds, such as adenine and adenosine, with chelating resins in fixed-beds have been extensively studied. However, a literature search indicates that there are very few studies concerning the kinetics of ligand adsorption in the continuous mode.
