چکیده

We show for the first time that stable fluorescent vesicles can be constructed by mixing oppositely-charged carbon quantum dots (CQDs) and simple surfactants in water, and can be potentially used as a new generation of biomarkers and drug delivery vehicles.

Synthesis and Optical Study of CdZnTe Quantum Dots

The comparison of growth processes and fluorescent properties of CdZnTe semiconductor quantum dots that are synthesized in different concentrations of Zn2+ in water are discussed in this paper. The samples are characterized through absorbtion (UV) and photoluminescence spectra (PL). The results show that when the reaction time is prolonged, the absorption peak and fluorescent emission peak pres...

Formulation of Insulin Containing Niosomes and the Effect of Their Oral Administration on Blood Glucose in Streptozotocin-induced Diabetic rats

Multilamellar vesicles (noisome) of polyoxyethylene alkyl ether surfactants (Brij 52, 72, 76 and 92) were prepared using classic film hydration method. Vesicle formation ability of the surfactants was assessed in presence or absence of cholesterol. All used surfactants formed vesicles in the absence of cholesterol. Recombinant human insulin was used as a model protein drug to investigate encaps...

DNA-lipid systems. A physical chemistry study.

It is well known that the interaction of polyelectrolytes with oppositely charged surfactants leads to an associative phase separation; however, the phase behavior of DNA and oppositely charged surfactants is more strongly associative than observed in other systems. A precipitate is formed with very low amounts of surfactant and DNA. DNA compaction is a general phenomenon in the presence of mul...

The potentiality of the functionalized nitrogen and thiol-doped graphene quantum dots (GQDs-N-S) to stabilize the antibodies in the designing of human chorionic gonadotropin immunosensor

In this study, for the first time, a simple immunosensor for ultrasensitive recognition of Human Chorionic Gonadotropin (hCG) in serum samples was fabricated by exploiting a simple approach. In this method, a low-cost and sensitive immunosensor was fabricated based on QDs-N-S/Au nanoparticles (NPs) modified Screen-Printed Carbon Electrode (SPCE). It seems that, QDs-N-S/Au NPs/ antibody as a bio...
