Background: Quantum dots (QDs) are among the most promising items in the nanomedicine toolbox. These nanocrystal fluorophores have several potential medical applications including nanodiagnostics, imaging, targeted drug delivery, Nevertheless, in vivo cytotoxicity of these nanoparticles has not been highly considered. For this reason, the cytotoxic effects of CdSe QDs on testis and epididymis e...

The chemical spray pyrolysis method was used to deposit CuInS2 (CIS) thin films and Au nanoparticles (NPs) in two configurations: glass/Au-NP layer covered with CuInS2 film (Au-NP/CIS) and glass/CuInS2 films covered with Au-NP layer (CIS/Au-NP). According to X-ray diffraction (XRD), the spray of 2 mM HAuCl4 aqueous solution with a volume of 2.5 to 15 ml onto a glass substrate at 340°C results i...

Liquid crystal-nanoparticle composite systems have attracted particular attention for both academic interests and applications in inducing macroscopic alignment, altering electro-optic response of the liquid crystal hosts, generating ordered, tunable soft metamaterials. Herein, synthesis two shapes CuInS2 nanoparticles, tremelliform-like frame-like CuInS2, their utilization producing uniform ho...

Herein we report the possibility of using green and red emitting silica-coated cadmium selenide (CdSe) quantum dots (QDs) for remarkable stem and cancer cellular imaging, efficient cellular uptake and fluorescence imaging of semi and ultra-thin sections of tumor for in vivo tumor targeted imaging applications. The comparative studies of high contrast cellular imaging behaviours of the silica-co...

cuins2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  in  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. the effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  the nanostructures  were  characterized  by  means  of  ...

ABSTRACT Herein, we describe the synthesis and characterization of a conjugated donor-acceptor copolymer consisting of a pyrrolopyridazinedione (PPD) acceptor unit, and a benzodithiophene (BDT) donor unit. The polymerization was done via a Stille cross-coupling polycondensation. The resulting PPD-BDT copolymer revealed an optical bandgap of 1.8 eV and good processability from chlorobenzene solu...

Two-dimensional (2D) nanostructures have generated significant interest in the scientific community as a result of their high surface area and remarkable optoelectronic properties. In this work, we present a simple colloidal synthesis for ultrathin nanosheets of both In2S3 and CuInS2. Contradictory phase designations exist for In2S3 at the nanoscale as a result of overlapping reflections from m...

An indigenously developed chemical spray pyrolysis system was used to deposit polycrystalline CuInS2 thin films. It was found that smaller spray rate results in films with better crystallinity and lower resistivity. Increase in surface roughness of the films was observed for higher spray rates. Variations in film stoichiometry with composition of spray solution were analyzed along with its opto...
