Piperine Loaded Titanium Dioxide Nanoparticles: Development, Characterisation and Biomedical Application

TiO₂ nanoparticles were prepared by using electrochemical anodization method. UV-Vis absorption spectrum of TiO₂ and TiO₂: piperine nanoparticles have an absorption edge in the range of (340 -355) nm, suggesting that the TiO₂ colloidal obtained is anatase phase. The band gap energy (E_g) for TiO₂ nanoparticles (3.46 eV) is higher than the value of (3.20 eV) for bulk TiO₂. X-Ray diffraction results for TiO₂ nanoparticles with a wavelength of 1.54 Å were investgation in this work. Planes (101), (200), (111), (220), (210), (211), (105), (220), (310), (221), and (220) crystal planes all had peaks with the lattice constants a = 3.755 Å and c = 9.5114Å confirms the anatase phases of the TiO₂ nanoparticles according to the JCPDS file 21-1272 31. Scanning Electron Microscope images of TiO₂ samples in revealed the prevalence spherical nanosized crystallites, where clear nanostructures with a grain size of 15 nm. In TEM image, the shape of the nanoparticles was spherecial, with small size variance and found to be 15 nm. The EDX study of the nanoparticle reflects the atomic percentage of elements such as Ti and O with a ratio of 83:17 and no other peaks are observed this confirm the presence of TiO₂ nanoparticles.
