• DNA Cleavage: We are interesting in synthesizing highly reactive artificial nucleases that can rapidly and selectively catalyze the cleavage of the P-O bonds in DNA and phosphodiesters under physiologicl conditions. A large number of mono and dinuclear Co(II) and Cu(II) complexes derived from pyridyl tripod amines and phenolic binucleating ligands were synthesized and characterized, and their catalytic hydrolysis in promoting the DNA cleavage as well as phosphodiester hydrolysis are tested.
• Anticancer Compounds: The search for an effective therapeutic anti-tumor compounds requires lowering the therapeutical dosage of the drug and also reducing its toxicity. To achieve this target we testing a new series Cu(II) and Co(II) based different tripod amines that derived from heterocyclic bases such as pyrzolyl  and imidazolyl groups.
• Carbon Dioxide Fixation: Recently, we have been involved in the synthesis of a series of polynuclear metal(II) complexes that efficiently can absorb the atmospheric CO2 from the air and convert it into carbonate that bridges several metal ions that can serve as the green chlorophyll and hence reduce the global warming.
• We are also interested in the design of inorganic molecules of novel magnetic properties that can utilizes some applications in Material Sciences; Single Molecular Magnets (SMM) and Field-Induced Single-Ion Magents (SIMs) which have important applications in ultra-high density magnetic information storage.  The strategy for synthesizing these compounds depends on the assembly of paramagnetic centers (Cu2+, Ni2+, Co2+) via bridging ligands. Other compartmental ligands accommodate two metal ions or more that can act as bridging ligands.  These ligands are used to synthesize polynuclear 3d-3d and 3d-4f metal ions.
