At pH 7.4 the nanoparticles exhibited a core–shell structure and good in vitro stability with very little d...

In this work, we report the production of PTS micelles for the encapsulation and delivery of a hydrophobic derivative of methotrexate, MTX di-ethylated (MTX-OEt). We optimized the micelles production by testing two different techniques: auxiliary solvent and son...

In this study, the elucidation of mechanisms underlying the anticancer effects of the apigenin, luteolin and myricetin will be new knowledge about preventive strategies against epithelial ovarian cancer in which the effect of flavonoids is still unclear. The cytotoxic effect of flavonoids was assessed by MTT analysis of the ovarian cancer cells (A2780, OVCAR-3 and SKOV-3) in comparison to the ovarian epithelial cells (OSE). The intracellular reactive oxygen species (ROS) generation, malondialdehyde (MDA) and protein carbonyl levels, caspase-3 and -9 activities were evaluated using fluorescence spectrometry. Apoptosis and c...

Authors: Yang Z, Sun Z, Ren Y, Chen X, Zhang W, Zhu X, Mao Z, Shen J, Nie S Abstract Nanomaterials play crucial roles in the diagnosis and treatment of diseases. Photothermal and photodynamic therapy, as two minimally invasive therapeutic methods, have promising potential in the diagnosis and prevention of cancer. Recently, many photothermal materials (such as noble metal material, transition metal sulfur oxides, carbon material and upconversion nanomaterial) and photodynamic materials (such as phthalein cyanogen, porphyrins and other dye molecules) have been applied in photothermal therapy (PTT) and photodynamic t...

Silver nanoparticles were prepared using Annona squamosa (AS) leaf extract as a potent bio-reducer and stabilizer. An intense surface plasmon resonance (SPR) band around 430 nm indicates the formation of well-stabilized silver nano particles, which was conform...

The influences of dextran molecular weight on the magnetite particle size and magnetic property of nano fluid were investigated. Magnetite produced at flow rate of 0.04 mL/s showed uniform particle size distribution with average size 10 nm and saturation magnetization (Ms) up to 60 emu/g. The X-ray diffraction pattern indicates pu...

Based on this biological function, exosomes have been used in numerous applications such as drug delivery. In this work, exosomes isolated from MCF7, Caco2, PC3 and HepG2 cell lines were characterized and loaded with bioactive compounds from black bean extract by electroporation. The cellular uptake and th...
