Item Fabrication and Characterization of Co3O4-Fe2O3-Chitosan Ternary Nanobiocomposite Electrode for Neurotransmitters Detection Applications(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2024) Talha Tariq; CIIT/FA22-RPH-008/LHR; Dr. Akbar Ali; LHR TP 9434This study focuses on the fabrication and characterization of a Co3O4-Fe2O3-Chitosan ternary nanobiocomposite electrode for detecting neurotransmitters, with a specific emphasis on Norepinephrine. The combination of these materials creates a unique electrochemical platform that offers enhanced sensitivity and selectivity for the detection of neurotransmitters, which are crucial biomarkers in diagnosing neurological diseases. The research involved synthesizing and analyzing Co3O4 nanoparticles, Co3O4-Fe2O3 (3:1) nanocomposites, Co3O4-Fe2O3-CS (3:1:2%) nanobiocomposites, and Co3O4-Fe2O3-CS (3:1:1%) nanobiocomposites. The nanobiocomposites, designed for neurotransmitter detection, specifically Norepinephrine, were thoroughly characterized and evaluated using a range of analytical techniques. These included X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy, Ultraviolet-Visible Spectroscopy (UV), Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), and Differential Pulse Voltammetry (DPV). The analyses provided valuable insights into the structural, morphological, and electrochemical properties of the fabricated nanobiocomposite electrode. These findings demonstrate its potential for accurately detecting Norepinephrine in biological samples with high sensitivity and selectivity.Item Synthesis of Silver Nano Particles with Arabic gum via Hydrothermal Method(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Laiba Hussain; FA16-BPH-004; Dr. Akbar Ali; LHR TP 5922Finely divided silver nanoparticles were synthesized via hydrothermal method. Arabic gum was used as reductant and steric-stabilizer both without any other material. Nano particles less than 100 nm have made an excellent impact in biomedical applications like diagnostic and medical devices for personalized health care particles. Silver nano particles with various characteristics can be-obtained by adjusting the reaction temperature, mass ratio of Arabic gum and silver nitrate. Sample products were characterized by FTIR, SEM and X-RD measurements. It was noticed that temperature and Arabic Gum played an important role in the synthesis-of silver nano particles. Well dispersed and fine form of silver nano particles were obtained under the conditions of 0.5 mmol/L AgNo3 m(Ag)/m(AgNo3)=1:1, 160 0C for 3hrs. We discussed the chemical cytoxicity and Plasmonic properties of nano particles and also the current application of AgNps.Item Synthesis And Characterization Of SrFeO3 Nanoparticles by Co-precipitation Method(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Usama Zahid , Muhammad Ikram; FA16-BPH-065 , FA16-BPH-023; Dr. Akbar Ali; LHR TP 5936In the past decade, magnetic nanoparticles have much attention due to their properties and technological applications. Strontium ferrite (SrFeO3) particles were prepared by co-precipitation method. The ferrite precursors have produced from aqueous mixtures of iron nitrate and strontium nitrate by co-precipitation, using potassium hydroxide aqueous solutions as precipitant. As above synthesis of strontium ferrite nanoparticles has prepared by co-precipitation method using iron nitrate and strontium nitrate and potassium hydroxide at different temperatures. The synthesis is characterizing by X-Ray Diffraction and Fourier Transform Infrared Spectroscopy. The x-ray points out the being formed SrFeO3 structure. Fourier transforms infrared spectroscopy point out functional group of particles and absorption related to metal oxygen vibration modes. This co-precipitation method allows a large-scale production of SrFeO3nanoparticles easily. The powder looks brownish.
