objective(s):the objective of this study was to determine the cytotoxic effects of nanoliposomal form of lyophilized aqueous extract of agrostemma githago (a. githago) seeds on gastric cancer cell line (ags) using cell viability tests. materials and methods: lyophilized aqueous extract of a. githago seeds was prepared. liposomes were also prepared by thin-film hydration method and their stabili...

objective(s):  the field of nanotechnology is rapidly expanding .the development quantum dots quantum dot (qds), show great promise for treatment and diagnosis of cancer and targeted drug delivery little data on the toxicity of qds, especially for in vivo applications, are available. as a result, concerns exist over their toxicity for in vivo applications. then, cytotoxic effects of cadmium sel...

objective(s): to improve water stability of electrospun chitosan/ polyethylene oxide (peo) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  materials and methods: different amounts of genipin were added to the chitosan/peo solutions, chitosan/peo weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

acute leukemia is characterized by the accumulation of neoplastic cells in the bone marrow and peripheral blood. currently, chemotherapy and differentiating agents have been used for the treatment of leukemia. recently, plant extracts, either alone or in combination with chemo agents, have been proposed to be used for the treatment of cancers. the aim of the present research was to study the cy...

background: multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. a rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles.objectives: herein, we report on a simple approach for the synthesis of ma...
