AgPO/AgPO photocatalysts were successfully synthesized by microwave-hydrothermal method. Tuning the properties of photocatalysts was achieved using different amount of acetic acid (CHCOOH) and sodium hydroxide (NaOH) to adjust pH value of precursor solution (pH = 4, 7, 10 and 12). The crystal structure, morphology and optical property of samples were characterized and explained.

The phase identification, morphology, and elemental composition of products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), field- emission scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX) spectroscopy, and Fourier transform infrared spectroscopy (FTIR). The results revealed the orthorhombic phase of SbS single crystal-forming sheaf-like nanostructure, and a possible formation mechanism was proposed and discussed.

The paramagnetic and molecularlike Fe-TA NPs were successfully synthesized at room temperature within a few minutes without the use of any toxic agents or expensive equipment. The coordination states of the Fe-TA NPs were pH-dependent.

The nanodrug is composed of carboxymethyl cellulose modified silver indium sulfide nanoparticle (CMC-AgInS NP, served as a source of reactive oxygen species) covalently linked with deferoxamine (DFO, served as iron chelating agent). The DFO/CMC-AgInS nanodrug was taken up by the HepG2 cell and accumulated within the cytosol as well as the nucleus, leading to induction of cell arrest in the G2/M phase and subsequent apoptosis cell death.

The theranostic nanoprobe combines the delivery potential of a non-toxic cellulose derivative polymer, specific capability of cancer-specific molecule (DNA-based EpCAM aptamer) and the imaging capability of magnetic iron oxide nanoparticles. Our proof-of-concept design demonstrates efficient in vitro MR imaging of the cancer cells, and enhanced delivery of an anticancer drug into the cancer cells with comparable treatment efficacy.
View Article and Find Full Text PDFCarboxymethyl modified magnetic nanoparticles (CMC-MNPs) have been designed as a vehicle for drug delivery in both drug-sensitive and drug-resistant cancer cells. We have demonstrated that the CMC-MNPs were able to load doxorubicin (DOX) with a high loading efficiency while also maintaining a good colloidal stability in an aqueous solution. According to a drug release study, DOX-loaded CMC-MNPs showed that the pH-dependent drug release property had a much higher release rate in acidic pH.

Oleic acid (OA) capped Bi2S3 quantum dots were successfully synthesized using 180 watt microwave power for 5 minutes in water-ethanol mixed solvents containing oleic acid as capping agent. In this approach, the reaction was conducted in ambient air and a much lower temperature than hot injection approach. The OA capped Bi2S3 QDs were characterized by using XRD, TEM, FTIR, UV-Vis and PL.

CMC, NaOH and hydrothermal temperatures have the influence on the product morphologies characterized using a scanning electron microscope (SEM) and a transmission electron microscope (TEM). PbS (cubic) composing of Pb and S was detected using an X-ray diffractometer (XRD), a selected area electron diffraction (SAED) technique and an energy dispersive X-ray (EDX) analyzer.
