The semiempirical (PM3) and DFT quantum mechanical methods were used to investigate the theoretical degradation of Indigo dye. The chemical reactivity of the Indigo dye was evaluated by comparing the potential energy stability of the mean bonds. Seven transition states were suggested and studied to estimate the actually starting step of the degradation reaction. The bond length and bond angle calculations indicate that the best active site in the Indigo dye molecule is at C10=C11. The most possible transition states are examined for all suggested paths of Indigo dye degradation predicated on zero-point energy and imaginary frequency. The first starting step of the reaction mechanism is proposed. The change in enthalpy, Gibbs free energy and change in entropy of the overall reaction are equal to -548268.223 kcal/mol, 30831.951 kcal/mol and 48.552 cal/mol.deg, respectively. The activation energy is 46176.405 kcal/mol. The reaction rate is equal to .

Cisplatin is ([PtCl2(NH3)2] ( CDDP) or its antitumor properties, including the treatment of various solid tumor's). Clinical use of CDDP confirmed for different kind of cancer have been treated, including usage of complexes as Sb (antiprotozoal), Bi (antiulcer), Au (antiarthritic), Fe (antimalarial), Ag (antimicrobial) and Pt (anticancer) in the treatment of different drugs.

Binary nano oxide MgO/SiO2 synthesis, depending on rice husk ash as raw material to extract nano-silica oxide.The sample prepared with different ratios of Mg/Si (0.75:0.25,0.9:0.1,0.25:0.75, and 0.5:0.5). The series of the ratio of Mg/Si is characterized by using X-ray diffraction, EDX, FE SEM, and BET techniques. The effects of magnesium oxide on modifying silica amorphous on structural parameters and surface qualities have been identified. In silica gel extracted from rice husk ash, this interaction is suggested to be essential for the balanced surface acid: base sites about the strong MgO and SiO2 interaction and the performance of binary nano oxide MgO/SiO2 based on the difference in the ratio of Mg/Si activity and physicochemical properties. According to results produced by binary oxide MgO/SiO2 ratio (0.5:0.5) of Mg/Si it has high activity with mesoporous having a significant surface area and pore distribution that has more activity against Gram-negative bacteria (E.Coli) at a concentration of 625 µg/mL, as well as using binary nano oxide MgO/SiO2 to make wound dressings that operate as antimicrobial. In vitro cytotoxic effects were studied of composites MgO/SiO2 (NPS) on Vero cell line 101 and skin cell line- A431. Different concentrations were investigated. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to determine the cytotoxic effects of green synthesized nanopowder. This study involved preparations for medical ointments with therapeutic efficacy by studying the effect of these ointments on S. aureas bacteria burns and wounds.
