Doxorubicin Loaded Magnesium Oxide Nanoflakes as pH Dependent Carriers for Simultaneous Treatment of Cancer and Hypomagnesemia

Nanomaterials (2019)

Tharindu A. Ranathunge D.G.G.P. Karunaratne R.M.G. Rajapakse Davita L. Watkins

Doxorubicin (DOX) is an anticancer drug commonly used in treating cancer; however, it has severe cytotoxicity effects. To overcome both the adverse effects of the drug and mineral deficiency (i.e., hypomagnesemia) experienced by cancer patients, we have developed magnesium oxide (MgO) nanoflakes as drug carriers and loaded them with DOX for use as a targeted drug delivery (TDD) system for potential application in cancer therapy. The synthesis employed herein affords pure, highly porous MgO nanoparticles that are void of the potentially harmful metal contaminants often discussed in the literature. Purposed for dual therapy, the nanoparticles exhibit an impressive 90% drug loading capacity with pH dependent drug releasing rates of 10% at pH 7.2, 50.5% at pH 5.0, and 90.2% at pH 3. Results indicate that therapy is achievable via slow diffusion where MgO nanoflakes degrade (i.e., dissolve) under acidic conditions releasing the drug and magnesium ions to the cancerous region. The TDD system therefore minimizes cytotoxicity to healthy cells while supplying magnesium ions to overcome hypomagnesemia.

Novel Liquid Crystal Display on Polyaniline Modified Glass

Molecular crystals and liquid crystals science technology. Section A, Molecular crystals and liquid crystals/Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals (1997)

A. D. L. Chandani R.M.G. Rajapakse L. P. P. Lankeshwara N. L. W. L. Kumarasiri

Abstract Novel liquid crystal (LC) cells were fabricated using polyaniline covalently attached onto ordinary glass surfaces. The latter fulfils three functions, namely, the substrate, the conducting medium and the template for the alignment of LC molecules. Both nematic and ferroelectric LC cells fabricated show perfect alignments and require comparatively low voltage for the switching of molecular orientations from one to another.
